等待安装完成,点Reboot按钮。 配置静态IPv4:
$ systemctl status NetworkManager.service
检查网络管理器服务状态 注1:建议使用nmtui的终端用户界面代替下面到92行左右的网络配置内容。
注2:Ubuntu 18.04 Server 使用了netplan进行网络管理,包括nameservers配置,请搜索下面的“netplan配置”。 $ nmcli dev status
DEVICE TYPE STATE CONNECTION
ens33 ethernet disconnected --
lo loopback unmanaged --
这里需要配置ens33 $ su
# cd /etc/sysconfig/network-scripts
# ls ifcfg*
# vi ifcfg-ens33
配置的ens33 将 BOOTPROTO=dhcp 改为 BOOTPROTO=static
然后在下行添加:
IPADDR=192.168.48.10
NETMASK=225.225.225.0
NM_CONTROLLED=no (NM_CONTROLLED=no表示该接口通过该配置文件设置,而不是通过网络管理器)
将 ONBOOT=no 改为 ONBOOT=yes
(如果虚拟机NAT访问,加入网关设置
GATEWAY=192.168.48.2
NETWORK=192.168.48.0

------------------------------------------ 配置光盘为安装源(注:后面有配置iso为安装源的,这里仅光盘镜像临时作为安装源使用):
$ sudo ssh 192.168.48.10 -l root
# cat /etc/yum.repos.d/CentOS-Media.repo
基本内容如下:
[c7-media]
name=CentOS-$releasever - Media

file:///media/cdrom/
file:///media/cdrecorder/
gpgcheck=1
enabled=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7
文件头的注释部分提示可以用命令
yum --enablerepo=c7-media [command]
或者
yum --disablerepo=\* --enablerepo=c7-media [command]
安装软件。 # ls /dev/cdrom
# mkdir /media/cdrom
# mount /dev/cdrom /media/cdrom
挂载cdrom [freeBSD
先载入光盘
或者挂载到/dist目录:
# mkdir -p /dist
# mount -t iso9660 /dev/cd0 /dist
用bsdconfig命令
# bsdconfig
选择 3.Packages
选择 1.CD/DVD
选择 FREEBSD_INSTALL ISO9660 file system
在其中选择要安装的软件
] 安装vim、gcc、g++:
# yum --disablerepo=\* --enablerepo=c7-media install vim -y
# yum --disablerepo=\* --enablerepo=c7-media install gcc gcc-c++ -y ----------------
安装mysql 5.6:
----------------
先将client和server两个rpm安装包复制到本机下载目录,然后在mac终端输入:
$ sudo scp ~/Downloads/MySQL-*.rpm bob@192.168.48.10:/home/bob/
复制client和server安装文件到/home/bob/目录下(注:也可以复制到其他目录,比如root@192.168.48.10:/usr/local/)
回到ssh:
# rpm -qa|grep -i mariadb
查询mariadb,与mysql冲突,下面将查到的库一并强制删除(最小安装只有mariadb-libs)
# rpm -e --nodeps mariadb-libs
# groupadd -r mysql
# useradd -g mysql mysql -d /home/mysql -s /sbin/nologin
(注:mysql 5.7论坛版安装顺序是:common、libs、client、server)
(注2:mariadb 10.2需要一些依赖:yum --disablerepo=\* --enablerepo=c7-media install lsof perl rsync boost perl-DBI -y
然后安装顺序是:galera、MariaDB-10.2.10-centos73-x86_64-*(放在同一目录下:compat、common、client、server)

# yum --disablerepo=\* --enablerepo=c7-media install perl -y
# rpm -ivh ./MySQL-client-5.6.34-1.el7.x86_64.rpm
# yum --disablerepo=\* --enablerepo=c7-media install autoconf -y
# rpm -ivh ./MySQL-server-5.6.34-1.el7.x86_64.rpm
# rm -f MySQL-*.rpm
# systemctl start mysql.service
(注:mysql 5.7的启动服务是mysqld.service)
(注2:mariadb 10.2启动服务是mysqld.service,mariadb也可以)
# cat /root/.mysql_secret
The random password set for the root user at Tue Feb 21 13:55:26 2017 (local time): vZQwDJLbxm_zHno_
(注:mysql 5.7的初始密码在log文件里
$ grep "temporary password" /var/log/mysqld.log
然后在调用mysql_secure_installation前,手动修改安全策略:
$ mysql -uroot -p
mysql> set global validate_password_policy=0;
mysql> set global validate_password_length=0;
mysql> exit
或者编辑 /etc/my.cnf
[mysqld]
validate_password=off

(注2:mariadb 10.2没有初始密码,可以通过下面命令将密码设置为123456
/usr/bin/mysqladmin -u root password '123456'

# /usr/bin/mysql_secure_installation
把随机密码粘贴到提示符,根据提示,改变root密码,移除匿名账户,禁用root远程登录,移除测试数据库,刷新权限。
(注:mysql 5.7在设置了前面的密码策略后,可能要多次输入简单的密码来确认)
# mysql -uroot -p
创建新用户:
mysql> create user 'bob'@'%' identified by '123456';
(如果用root账户远程连接:mysql> grant all privileges on *.* to 'root'@'%' identified by '123456';)
mysql> flush privileges;
mysql> exit
# firewall-cmd --zone=public --add-port=3306/tcp --permanent
# firewall-cmd --reload
------ mysql emoji ------
注意:utf8mb4的最低mysql版本支持版本为5.5.3+
注意2:utf8mb4作为索引列需要注意,在MySQL 5.7.7和MariaDB 10.2.2中支持3072个字节最大索引,而MySQL5.6仅支持767个字节,
所以在mysql5.6时,utf8mb4列的长度不要超过191(191*4<767),utf8可以是255(255*3<767)。如要使用超过767个字节(升级到3072个),需要设置
SET GLOBAL innodb_file_per_table = ON,
innodb_file_format = Barracuda,
innodb_large_prefix = ON;
并且在建立表(包括ALTER)的时候,加上 ROW_FORMAT=DYNAMIC 或者 ROW_FORMAT=COMPRESSED
CREATE TABLE _tablename_(
`id` INT NOT NULL AUTO_INCREMENT,
`hashtag` VARCHAR(255) NOT NULL COMMENT 'hashtag must be unique. Must be saved without #',
PRIMARY KEY (`id`),
UNIQUE INDEX `hashtags_hashtag` (`hashtag` ASC))
)
ENGINE = InnoDB
DEFAULT CHARACTER SET utf8mb4
ROW_FORMAT = COMPRESSED;
ALTER就是:
ALTER TABLE _tablename_ ROW_FORMAT=DYNAMIC;
(mysql 5.7.9是默认innodb_default_row_format=DYNAMIC,innodb_file_per_table = ON,innodb_file_format = Barracuda,innodb_large_prefix = ON)
---
如果创建数据库、表、列时指定utf8mb4和utf8mb4_general_ci,下面应该可以不用设置。
1) 设置my.cnf
$ sudo vim /etc/my.cnf(ubuntu的位置 /etc/mysql/my.cnf)
[client]
default-character-set=utf8mb4 [mysql]
default-character-set=utf8mb4 [mysqld]
default_authentication_plugin=mysql_native_password // mysql 8 默认 caching_sha2_password,这里更改为原始的
character-set-client-handshake=FALSE
character-set-server=utf8mb4
collation-server=utf8mb4_unicode_ci
init_connect='SET NAMES utf8mb4' skip-name-resolve
保存后重启mysql
$ systemctl restart mysql
$ mysql -uroot -p
mysql> SHOW VARIABLES WHERE Variable_name LIKE 'character_set_%' OR Variable_name LIKE 'collation%';
+--------------------------+----------------------------+
| Variable_name | Value |
+--------------------------+----------------------------+
| character_set_client | utf8mb4 |
| character_set_connection | utf8mb4 |
| character_set_database | utf8mb4 |
| character_set_filesystem | binary |
| character_set_results | utf8mb4 |
| character_set_server | utf8mb4 |
| character_set_system | utf8 |
| character_sets_dir | /usr/share/mysql/charsets/ |
| collation_connection | utf8mb4_general_ci |
| collation_database | utf8mb4_unicode_ci |
| collation_server | utf8mb4_unicode_ci |
+--------------------------+----------------------------+
11 rows in set 注:collation_connection、collation_database、collation_server是utf8mb4_general_ci没有关系。 2) 修改Database、Table、Column字符集:
ALTER DATABASE database_name CHARACTER SET = utf8mb4 COLLATE = utf8mb4_unicode_ci;
ALTER TABLE table_name CONVERT TO CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;
ALTER TABLE table_name CHANGE column_name VARCHAR(191) CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci; 修复优化表
REPAIR TABLE table_name;
OPTIMIZE TABLE table_name;
也可以用mysqlcheck命令优化所有数据库
$ mysqlcheck -uroot -p --auto-repair --optimize --all-databases 3) 对于Java来说mysql connector版本需高于5.1.13。 ------------
安装gogs:
------------
先将linux_amd64.zip包复制到本机下载目录,然后在mac终端输入:
$ sudo scp ~/Downloads/linux_amd64.tar.gz root@192.168.48.10:/root/
复制linux_amd64.tar.gz文件到/root/目录下(注:也可以复制到其他目录,比如root@192.168.48.10:/usr/local/)
回到ssh:
# groupadd -r git
# useradd -g git git -d /home/git
# mv /root/linux_amd64.tar.gz /home/git/
# chown git:git /home/git/linux_amd64.tar.gz
(如果是zip文件:yum --disablerepo=\* --enablerepo=c7-media install unzip -y)
# su git
$ cd ~
$ tar xvfz linux_amd64.tar.gz
(如果是zip文件:unzip linux_amd64.zip)
$ ls
gogs linux_amd64.tar.gz
$ rm -f linux_amd64.tar.gz
$ cd gogs
$ chmod +x ./gogs
$ cat ./scripts/mysql.sql
DROP DATABASE IF EXISTS gogs;
CREATE DATABASE IF NOT EXISTS gogs CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci;
$ mysql -uroot -p < scripts/mysql.sql
$ mysql -uroot -p
mysql> grant all privileges on gogs.* to 'bob'@'%' identified by '123456';
mysql> flush privileges;
mysql> exit
$ exit
# cp /home/git/gogs/scripts/systemd/gogs.service /etc/systemd/system/

Environment=USER=git HOME=/home/git [Install]
WantedBy=multi-user.target 启动服务,配置防火墙
# systemctl start gogs.service
# systemctl enable gogs.service
# firewall-cmd --zone=public --add-port=3000/tcp --permanent
# firewall-cmd --reload
(ubuntu系统配置防火墙命令:
sudo ufw allow 3000
sudo ufw enable)
(iptables:
// 添加
iptables -A INPUT -p tcp --dport 22 -j ACCEPT
iptables -A OUTPUT -p tcp --sport 22 -j ACCEPT
// 保存
service iptables save
cat /etc/sysconfig/iptables
// 重启iptables
service iptables restart
iptables -nvL --line-number
// 删除
iptables -D INPUT 2 <--- line number
// 修改
iptables -R INPUT 3 -j ACCEPT
) 然后在浏览器打开
http://192.168.48.10:3000
(注2:mariadb配置好后,主机也许不能用127.0.0.1连接,请用主机ip:192.168.48.10) 注:如果开启了selinux,可能需要关闭。
# setenforce 0
# vim /etc/sysconfig/selinux
将SELINUX=enforce改为disabled
配置文件为了保证重启后生效。 无法使用ssh进行clone和push数据
如果http方式没问题,就是应为gogs的账户(这里是git账户)没有指定shell,
解决办法是:
# cat /etc/shells
/bin/sh
/bin/bash
...
# usermod -s /bin/bash git 升级gogs
$ sudo service gogs stop
$ sudo su - git
$ cd ~
$ pwd
/home/git
$ ls
gogs gogs-repositories
$ mv gogs gogs_old $ wget https://dl.gogs.io/gogs_v$VERSION_$OS_$ARCH.tar.gz
$ tar -zxvf gogs_v$VERSION_$OS_$ARCH.tar.gz
$ ls
gogs gogs_old gogs-repositories gogs_v$VERSION_$OS_$ARCH.tar.gz $ cp -R gogs_old/custom gogs
$ cp -R gogs_old/data gogs
$ cp -R gogs_old/log gogs $ sudo service gogs start 如果启动失败,可能是权限的问题:
# chmod +x /home/git/gogs/gogs
# chown -R git:git /home/git/gogs
# service gogs start ---------

# sudo yum makecache (( manjaro
镜像源
$ sudo pacman-mirrors -i -c China -m rank //更新镜像排名
然后出现界面勾选某个镜像源
$ sudo pacman -Syy //更新数据源
$ sudo pacman -S pacman
$ sudo pacman -S vim yaourt
$ sudo vim /etc/yaourtrc
AURURL="https://aur.tuna.tsinghua.edu.cn"
$ sudo yaourt -Syy
在包管理器的设置中,将AUR设置为启用。
然后可以安装Sogou等输入法。
)) 安装sudo
[ freeBSD
pkg install vim sudo ]
$ su
# vim /etc/sudoers
[ freeBSD
vim /usr/local/etc/sudoers ]
在 root ALL=(ALL) ALL后面添加相同一行,新行的root改成当前用户,然后w!写入,退出vim
# exit
$
就可以了。 安装vim
# yum install vim 安装deltarpm
# yum provides '*/applydeltarpm'
# yum install deltarpm 安装开发组工具
# yum group list | grep "Development Tools"
# yum group install "Development Tools"
(debian: apt-get install build-essential) 安装ack
# yum install epel-release
# yum install ack
其中epel-release指的是:Extra Packages for Enterprise Linux (EPEL)
Fodera直接
# dnf install ack -y
Debian
$ sudo apt install ack-grep 安装zsh
# cat /etc/shells
# yum install zsh [freeBSD #pkg install zsh]
# zsh --version
# echo $SHELL
# chsh -s /bin/zsh (yum install util-linux-user) [freeBSD #chsh -s /usr/local/bin/zsh]
如果提示用户名不存在,说明用户不在/etc/passwd中,可能是LDAP-base系统,可以通过下面命令查看用户信息
$ getent passwd $USER
yourusername:*:700607997:700600513:somedomain.com:/home/yourusername:/bin/bash
可以更改.profile或者.bashrc文件(因为上面写了/bin/bash)
if [ "$SHELL" != "/bin/zsh" ]
then
export SHELL="/bin/zsh"
exec /bin/zsh -l # -l: login shell again
fi # zsh
选择2,生成默认配置文件~/.zshrc
如果改变失败,可以用usermod命令:
$ sudo usermod -s /bin/zsh $USER
(
创建组和用户
# groupadd -r bob
# useradd -g bob bob -d /home/bob -s /bin/bash
# passwd bob
# mkdir /home/bob
# chown -R bob:bob /home/bob
# vi /etc/sudoer
...
) 安装antigen(https://github.com/zsh-users/antigen)
$ cd ~
[freeBSD #pkg install curl git]
$ curl -L git.io/antigen > antigen.zsh
$ vim ~/.antigenrc
source $HOME/antigen.zsh

$ echo source \$HOME/.antigenrc>~/.zshrc
****如果不在zsh
$ zsh
$ chsh -s /bin/zsh
****如果在zsh
$ source ~/.zshrc
$ antigen list
如果出现问题可以reset一下:
$ antigen reset 注意:如果启动zsh时候提示
zsh compinit: insecure directories, run compaudit for list.
输入 compaudit 查看不安全的目录,然后用chmod 755(或chown)命令改变这些目录权限
$ compaudit
There are insecure directories:
/home/Bob/.antigen/bundles/robbyrussell/oh-my-zsh/lib
/home/Bob/.antigen/bundles/robbyrussell/oh-my-zsh/plugins/git
...
$ ls -al /home/Bob/.antigen

sshd:
先查看运行状态
# systemctl status sshd.service

# yum -qa|grep -i ssh (dnf list installed|grep -i ssh)
openssh.x86_64
openssh-clients.x86_64
openssh-server.x86_64
# yum install openssh
(ubuntu中已经安装了openssh-client,因此安装Server
$ sudo apt install openssh-server
)
其配置文件在:/etc/ssh/sshd_config
最后记得将端口加入防火墙策略里。 启动sshd服务
# systemctl start sshd.service
# systemctl enable sshd.service 远程连接
$ ssh root@192.168.48.128 可以用scp、sftp等命令进行文件传输,简单格式如:
$ scp [[user@]host1:]file1 ... [[user@]host2:]file2 xstart + ssh:
终端:/usr/bin/gnome-terminal
文件管理器:/usr/bin/nautilus
其他可以用whereis命令查询
# where firefox
# whereis firefox 配置SSH(在本机生成sshkey,然后将公钥加入到远程authorized_keys中)

$ /usr/local/bin/gpg --version
gpg (GnuPG) 2.2.10

Copyright (C) 2018 Free Software Foundation, Inc.
...
将环境变量添加到启动配置,如.bashrc中
$ echo export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH >> ~/.bashrc 同理检查PATH环境变量,使/usr/local/bin在/usr/bin前,然gpg命令直接运行我们编译的版本。
重新进入会话,输入 gpg --version 应该是刚才安装的版本。 必要组件安装:
---
// 用于输入密码保护(必须)
$ cd ../pinentry-1.1.0
$ ./configure
$ sudo make && sudo make install ---
下面两个可选,可能需要修改库的路径,configure才能正确通过。
// GPGME is the standard library to access GnuPG functions from programming languages.
$ cd ../gpgme-1.11.1
$ ./configure
$ sudo make && sudo make install // GPA is a graphical frontend to GnuPG.
$ cd ../gpa-0.9.10
$ ./configure
$ sudo make && sudo make install

可以使用help了解更多命令。 6. 应用
- 可在github设置 -> SSH and GPG keys里,添加生成PGP KEY,注意使用对应的邮箱和user id的GPG KEY
- 可用于git签名,如
$ git config --global user.signingkey F461FA2D923C3798 提交的签名
$ git config commit.gpgsign true
$ git config --global commit.gpgsign true
然后提交代码(-S):
$ git commit -S -m your commit message tag的签名(-s)
$ git tag -s mytag
验证(-v)
$ git tag -v mytag - 使用gpg-agent帮助减少密码输入,可将下面命令写入~/.xsession、 ~/.profile或者.bash_profile等启动文件
eval $(gpg-agent --daemon) -----------------
排除故障

$ export GPG_TTY=$(tty)
$ echo 'export GPG_TTY=$(tty)' >> ~/.zshrc // 或者.bashrc, .bash_profile 故障:apt: Unknown error executing apt-key
解决:
sudo apt-get clean

安装方式一:
MacOS
$ brew install git-flow
或者
$ wget --no-check-certificate -q -O - https://github.com/nvie/gitflow/raw/develop/contrib/gitflow-installer.sh | sudo bash
Debian
$ apt-get install git-flow
Fedora
$ yum install gitflow 安装方式二:手动安装
手动安装方法1(推荐)
$ git clone --recursive git://github.com/nvie/gitflow.git
$ cd gitflow
$ sudo make install
如果安装到其他目录,可以 $ sudo make prefix=/opt/local install
$ git flow version
$ cd ..
$ rm -rf gitflow 手动安装方法2
$ wget -q -O - https://github.com/nvie/gitflow/raw/develop/contrib/gitflow-installer.sh | sh
删除
$ sudo ./gitflow-installer.sh uninstall 版本:git flow version
zsh插件:git-flow、bobthecow/git-flow-completion
如果提示zsh compinit: insecure directories, run compaudit for list.
可以用下面命令更改权限
compaudit | xargs chmod -R 755 使用:分支feature/demo1,修改后合并到develop分支
$ git clone ...
$ cd ...
$ git flow init -d
$ git flow feature start demo1
// 修改代码
$ git flow feature finish demo1 分支模式学习文档:

... ----VNC----
VNC,在Windows端可以使用TightVNC/UltraVNC来连接Linux gnome桌面。
以ubuntu为例,在程序里打开Desktop Sharing程序,即可进行VNC配置,
默认是安全连接的,如果使用TightVNC连接,则需要关闭其安全连接,命令:
$ gsettings get org.gnome.Vino require-encryption
true
$ gsettings set org.gnome.Vino require-encryption false 另外,Ubuntu gnome还有一个Remmina Remote Desktop Client软件,用来连接包括VNC方法在内的客户端工具。 ----重置root密码----
适用于systemd的centos等发行版本。如果启用了LUKS等加密硬盘,需要输入LUKS密码。
1. 在GRUB引导界面,输入e,进入编辑界面
2. 将光标移动到Linux16这行,删除rhgb quiet,替换为rd.break enforcing=0
然后按下Ctrl+X启动,系统进入紧急模式
3. 挂载硬盘然后修改密码:
# mount -o remount,rw /sysroot
# chroot /sysroot
# passwd
修改后输入两次exit重启系统
4. 用root身份登陆恢复/etc/shadow的SELinux标签
# restorecon -v /etc/shadow
# setenforce 1 ----pacman----
*自升级
pacman -S pacman
*查询
pacman -Ss yaourt
*安装
pacman -S yaourt vim curl git
*删除
pacman -R yaourt
pacman -Rs yaourt // 同时删除无用的依赖
*删除无用的包
sudo pacman -Rcs $(pacman -Qdtq) // 比-R移除,包括递归软件包
sudo pacman -R $(pacman -Qdtq)
*全部升级
pacman -Syu
或者pacman -Syyu
*清理和回滚
以根用户权限执行降级系统命令。为了顺利执行,可能需要先清除系统缓存
缓存位置:/var/cache/pacman/pkg
pacman -Scc
# 启用降级
pacman -Syyuu ----工具----
*7Z
sudo yum install p7zip
sudo apt install p7zip-full
sudo pacman -S p7zip * HTOP (如果安装了linuxbrew,也可以用brew命令安装)
sudo yum install htop
sudo apt install htop
sudo dnf install htop
sudo pacman -S htop
brew install htop * HTTPIE
sudo pip3 install httpie
brew install httpie * CHT.SH
curl cht.sh/:help sudo pacman -S xsel rlwrap
mkdir -p ~/bin
curl https://cht.sh/:cht.sh > ~/bin/cht.sh
chmod +x ~/bin/cht.sh

// 更新
# yum update google-chrome-stable ***debian/ubuntu
# echo 'deb [arch=amd64] http://dl.google.com/linux/chrome/deb/ stable main' > /etc/apt/sources.list.d/google-chrome.list
或者编辑/etc/apt/sources.list,加入 deb http://dl.google.com/linux/chrome/deb/ stable main
# wget -q -O - https://dl-ssl.google.com/linux/linux_signing_key.pub | sudo apt-key add -
或者
wget https://dl-ssl.google.com/linux/linux_signing_key.pub
apt-key add linux_signing_key.pub # apt-get update
# apt-get install google-chrome-stable ***arch/manjaro (编译离线版本)
方法一(推荐):yaourt
# yaourt -S google-chrome
按提示输入如下:
Edit PKGBUILD ? n
Edit google-chrome.install ? n
Continue building google-chrome ? y
等待打包完成,提示导出 google-chrome 到 /var/cache/pacman/pkg/ 目录,可能要输入密码。
Continue installing google-chrome ? y
::Proceed with installation? y
等待安装完成。
方法二:不使用yaourt
打开 https://aur.archlinux.org/packages/google-chrome/
复制 Git Clone URL: https://aur.archlinux.org/google-chrome.git
$ git clone --depth 1 https://aur.archlinux.org/google-chrome.git
$ cd google-chrome
$ makepkg -s
等待下载打包完成,会得到 google-chrome-69.0.3497.92-1-x86_64.pkg.tar.xz
然后用pacman安装
$ sudo pacman -U google-chrome-69.0.3497.92-1-x86_64.pkg.tar.xz
安装完成后可删除不要的文件
$ cd ..
$ rm -rf google-chrome * Linuxbrew
sh -c "$(curl -fsSL https://raw.githubusercontent.com/Linuxbrew/install/master/install.sh)"
会提示创建的目录,包括(/home/linuxbrew),输入enter继续安装,其他键停止安装。
如果出现错误:Error: Git must be installed and in your PATH!
设置环境变量(注意:这里全部以zsh shell为例):
echo "export HOMEBREW_NO_ENV_FILTERING=1" >> ~/.zshrc
重启shell后再次执行
/home/linuxbrew/.linuxbrew/bin/brew update --force 然后执行配置
test -d ~/.linuxbrew && PATH="$HOME/.linuxbrew/bin:$HOME/.linuxbrew/sbin:$PATH"
test -d /home/linuxbrew/.linuxbrew && PATH="/home/linuxbrew/.linuxbrew/bin:/home/linuxbrew/.linuxbrew/sbin:$PATH"
test -r ~/.bash_profile && echo "export PATH='$(brew --prefix)/bin:$(brew --prefix)/sbin'":'"$PATH"' >>~/.bash_profile
echo "export PATH='$(brew --prefix)/bin:$(brew --prefix)/sbin'":'"$PATH"' >>~/.zshrc
重启shell 安装常用工具 brew install bat
echo "alias cat='bat'" >> ~/.zshrc brew install fzf
$(brew --prefix)/opt/fzf/install vim ~/.zshrc
alias preview="fzf --preview 'bat --color \"always\" {}'"
# 支持在 VS Code 里用 ctrl+o 来打开选择的文件
export FZF_DEFAULT_OPTS="--bind='ctrl-o:execute(code {})+abort'"
重启shell brew install prettyping
echo "alias ping='prettyping --nolegend'" >> ~/.zshrc brew install htop brew install diff-so-fancy
vim ~/.gitconfig
[pager]
diff = diff-so-fancy | less --tabs=1,5 -RFX
show = diff-so-fancy | less --tabs=1,5 -RFX brew install ncdu
echo 'alias du="ncdu --color dark -rr -x --exclude .git --exclude node_modules"' >> ~/.zshrc brew install tldr
echo "alias help='tldr'" >> ~/.zshrc
tldr bat 安装ack和ng
brew install ack
brew install the_silver_searcher 安装fd
brew install fd
注意:会自动检查依赖并安装编译,其中rust,会非常慢(超过一个小时)。
例子:
$ fd cli # 所有包含 "cli" 的文件名
$ fd -e md # 所有以 .md 作为扩展名的文件
$ fd cli -x wc -w # 搜索 "cli" 并且在每个搜索结果上运行 `wc -w`
