z’saved [643790848/643790848]方式二 下载mysql-5.7.22-linux-glibc2.12-x86_64.tar.g
z包 用xftp上传至 用户的 /usr/src下
第二步 创建用户和组 解压软件至/usr/local
[root@localhost src]# ls
debug kernels mysql-5.7.22-linux-glibc2.12-x86_64.tar.gz
[root@localhost src]# tar xf mysql-5.7.22-linux-glibc2.12-x86_64.tar.gz -C /usr/local/
第三步 创建用户和组
[root@localhost src]# groupadd -r mysql
[root@localhost src]# useradd -M -s /sbin/nologin -g mysql mysql
[root@localhost src]# cd /usr/local/
[root@localhost local]# ln -sv mysql-5.7.22-linux-glibc2.12-x86_64/ mysql
//软链接
‘mysql’ -> ‘mysql-5.7.22-linux-glibc2.12-x86_64/’
[root@localhost local]# ll

drwxr-xr-x. 5 root root 49 Jun 13 19:03 share
drwxr-xr-x. 2 root root 6 Mar 10 2016 src
第四步 修改目录/usr/local/mysql的属主属组
[root@localhost local]# chown -R mysql.mysql mysql
第五步 添加环境变量
[root@localhost local]# ls /usr/local/mysql
bin COPYING docs include lib man README share support-files
[root@localhost local]# echo ‘export PATH=/usr/local/mysql/bin:$PATH‘ > /etc/pro
file.d/mysql.sh
[root@localhostlocal]# source /etc/profile.d/mysql.sh
[root@localhost local]# echo $PATH //测试一下mysql环境变量
/usr/local/mysql/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root
/bin
//默认的所有命令都只会从这里识别
第六步 建立数据存放目录
[root@localhost local]# mkdir /opt/data
[root@localhost local]# chown -R mysql.mysql /opt/data/
[root@localhost local]#cd
第七步 初始化数据库
[root@localhost local】#cd
[root@localhost ~]# mysqld --initialize --user=mysql --datadir=/opt/data/

e is deprecated. Please use --explicit_defaults_for_timestamp server option
(see documentation for more details).

2018-08-15T07:57:51.078089Z 1 [Note] A temporary password is generatedfor ro
ot@localhost: jtBzkkb=r5ik
//最后一个才是生成的临时密码
第八步 生成配置文件
[root@localhost ~]# cat > /etc/my.cnf <<EOF
> [mysqld]
> basedir = /usr/local/mysql
> datadir = /opt/data
> socket = /tmp/mysql.sock
> port = 3306
> pid-file = /opt/data/mysql.pid
> user = mysql
> skip-name-resolve
> EOF
//检查一下
[root@localhost ~]# cat /etc/my.cnf
[mysqld]
basedir = /usr/local/mysql
datadir = /opt/data
socket = /tmp/mysql.sock
port = 3306
pid-file = /opt/data/mysql.pid
user = mysql
skip-name-resolve
第九步 配置服务启动脚本
[root@localhost ~]# cp -a /usr/local/mysql/support-files/mysql.server /etc/i
nit.d/mysqld
[root@localhost ~]#vim /etc/init.d/mysqld
找到basedir 第一个是 解压包的路径
第二个是 数据存储的路径
最后启动mysql
[root@localhost ~]#service mysqld start
Starting MySQL.Logging to ‘/opt/data/localhost.localdomain.err‘.
SUCCESS! //正常现象 第一次登录会报出
[root@localhost ~]# ss -antl

进入mysql
[root@localhost ~]#/mysql -uroot -p ‘jtBzkkb=r5ik’
