LNMP项目案例

1、环境准备

2、搭建backup服务器

# 关闭防火墙、selinux
[root@backup ~]# systemctl stop firewalld
[root@backup ~]# setenforce 0

# 安装rsync
[root@backup ~]#  yum install rsync -y

# 统一用户
[root@backup ~]# useradd -u1000 www
[root@backup ~]# id www
uid=1000(www) gid=1000(www) groups=1000(www)

# 编写配置文件（前端代码仓库、数据库备份、上传文件的备份）
[root@backup ~]# vim /etc/rsyncd.conf 
uid=www
gid=www
port=873
fake super=yes
use chroot=no
max connection=200
timeuot=600
ignore errors
read only=false
list=false
auth users=dandan
secrets file=/etc/rsync.passwd
log file=/var/log/rsyncd/log
###################################
[web]
comment="前端代码仓库"
path=/backup/web
[database]
comment="数据库备份"
path=/backup/database
[download]
comment="上传文件备份"
path=/backup/download

# 创建仓库
[root@backup ~]# mkdir /backup
[root@backup ~]# mkdir /backup/web
[root@backup ~]# mkdir /backup/database
[root@backup ~]# mkdir /backup/download
[root@backup ~]# tree /backup/
/backup/
├── database
├── download
└── web

# 授权
[root@backup ~]# chown www.www -R /backup/

# 创建密码文件
[root@backup ~]# echo "dandan：111" > /etc/rsync.passwd
[root@backup ~]# chmod 600 /etc/rsync.passwd

# 启动 (立即启动和设置开机自启)
[root@backup ~]# systemctl enable --now rsyncd

3、搭建NFS服务器

# 安装软件  nfs-utils rpcbind
[root@nfs ~]# yum install nfs-utils rpcbind -y

# 创建用户
[root@nfs ~]# useradd www -u1000

# 创建前端代码仓库、数据库备份、上传文件的备份
[root@nfs ~]# mkdir /nfs
[root@nfs ~]# mkdir /nfs/web
[root@nfs ~]# mkdir /nfs/database
[root@nfs ~]# mkdir /nfs/download
[root@nfs ~]# tree /nfs/
/nfs/
├── database
├── download
└── web

# 授权
[root@nfs ~]# chown www.www -R /nfs/

# 设置挂载点
[root@nfs ~]# vim /etc/exports
/nfs/web      172.16.1.0/20(rw,sync,all_squash,anonuid=1000,anongid=1000)
/nfs/database 172.16.1.0/20(rw,sync,all_squash,anonuid=1000,anongid=1000)
/nfs/download 172.16.1.0/20(rw,sync,all_squash,anonuid=1000,anongid=1000)

# 启动
[root@nfs ~]# systemctl enable --now nfs-server.service 
Created symlink from /etc/systemd/system/multi-user.target.wants/nfs-server.service to /usr/lib/systemd/system/nfs-server.service.

# 检测
[root@nfs ~]# showmount -e
Export list for nfs:
/nfs/download 172.16.1.0/20
/nfs/database 172.16.1.0/20
/nfs/web      172.16.1.0/20

[root@nfs ~]# cat /var/lib/nfs/etab   #另外一种检测的命令

4、搭建数据库（mariadb）

# 安装软件
[root@db01 ~]# yum install mariadb* -y

# 启动
[root@db01 ~]# systemctl enable --now mariadb
Created symlink from /etc/systemd/system/multi-user.target.wants/mariadb.service to /usr/lib/systemd/system/mariadb.service.

# 创建密码并登陆数据库
[root@db01 ~]# mysqladmin -uroot password ‘123‘
[root@db01 ~]# mysql -uroot -p123

# 创建用户给予web以及其它网站使用（授权）
MariaDB [mysql]> grant all privileges on *.* to dandan@‘%‘ identified by ‘dandan‘;
Query OK, 0 rows affected (0.01 sec)

#重载数据库
MariaDB [mysql]> flush privileges; 
Query OK, 0 rows affected (0.00 sec)

#备份数据库
[root@db01 ~]# mysqldump -uroot -p111 --all-databases --single-transaction > mysql-all.sql
[root@db01 ~]# cat mysql-all.sql

# 编写每天备份脚本
[root@db01 ~]# vim mysql_dump.sh   
#!/bin/bash
DATE=`date +%F`
BACKUP="/databases"
cd $BACKUP
mysqldump -uroot -p123 --all-databases --single-transaction > mysql-all-${DATE}.sql
tar -czf mysql-all-${DATE}.tar.gz mysql-all-${DATE}.sql
rm -rf mysql-all-${DATE}.sql

[root@db01 ~]# chmod 600 mysql_dump.sh   #授权
[root@db01 ~]# mkdir /databases          #创建目录
[root@db01 ~]# useradd www -u1000
[root@db01 ~]# chown www.www /databases/
[root@db01 ~]# mount -t nfs 172.16.1.31:/nfs/database /databases/     #挂载

# 脚本加入定时任务
[root@db01 ~]# crontab -e
01 00 * * *  /databases/mysql_dump.sh

5、搭建web服务器(点击xshell中的工具—>发送键输入到所有会话,web01-03)

# 安装官方源
[root@web01 ~]# vim /etc/yum.repos.d/nginx.repo
[nginx-stable]
name=nginx stable repo
baseurl=http://nginx.org/packages/centos/$releasever/$basearch/
gpgcheck=1
enabled=1
gpgkey=https://nginx.org/keys/nginx_signing.key
module_hotfixes=true

[nginx-mainline]
name=nginx mainline repo
baseurl=http://nginx.org/packages/mainline/centos/$releasever/$basearch/
gpgcheck=1
enabled=0
gpgkey=https://nginx.org/keys/nginx_signing.key
module_hotfixes=true
[root@web01 ~]# yum clean all
[root@web01 ~]# yum makecache

# 安装nginx
[root@web01 ~]# yum install -y nginx 

# 启动
[root@web01 ~]# systemctl enable --now nginx

6、安装PHP

# 安装PHP    #最好用安装包安装
[root@web01 ~]# vim /etc/yum.repos.d/php.repo
[php-webtatic]
name = PHP Repository
baseurl = http://us-east.repo.webtatic.com/yum/el7/x86_64/
gpgcheck = 0
[root@web01 ~]# yum clean all
[root@web01 ~]# yum makecache
[root@web01 ~]# yum remove php-mysql-5.4 php php-fpm php-common
[root@web01 ~]# yum -y install php71w php71w-cli php71w-common php71w-devel
php71w-embedded php71w-gd php71w-mcrypt php71w-mbstring php71w-pdo php71wxml php71w-fpm php71w-mysqlnd php71w-opcache php71w-pecl-memcached php71wpecl-redis php71w-pecl-mongodb

# 修改配置文件
[root@web01 ~]# vim /etc/php-fpm.d/www.conf 
user = www
group = www

# 启动php
[root@web01 ~]# systemctl enable --now php-fpm.service 

7、将web01-web03加入集群

[root@web02 ~]# mkdir /www
[root@web02 ~]# chown -R www.www /www/
[root@web02 ~]# mount  -t nfs 172.16.1.31:/nfs/web /www
[root@web02 ~]# mount -t nfs 172.16.1.31:/nfs/conf /etc/nginx/conf.d/
[root@web02 ~]# systemctl restart nginx

8、搭建wordpress,搭建WeCenter

# 共享代码、共享数据、共享nginx配置
# 在nfs服务器上创建/nfs/conf目录
[root@nfs ~]# mkdir /nfs/conf

# 授权/nfs/conf
[root@nfs ~]# chown www.www /nfs/conf

# 加入nfs配置文件
[root@nfs ~]# vim /etc/exports
/nfs/conf     172.16.1.0/20(rw,sync,all_squash,anonuid=1000,anongid=1000)

# 重启nfs
[root@nfs ~]# systemctl restart nfs-server rpcbind

# 创建站点目录,授权，挂载，上传，解压
[root@web01 ~]# mkdir /www
[root@web01 ~]# chown www.www -R /www
[root@web01 ~]# mount -t nfs 172.16.1.31:/nfs/web /www
[root@web01 ~]# mount -t nfs 172.16.1.31:/nfs/conf /etc/nginx/conf.d
[root@web01 ~]# cd /www
[root@web01 www]# rz -E
rz waiting to receive
[root@web01 www]# unzip zhihu.zip 

# 增加wordpress配置
[root@web01 ~]# vim /etc/nginx/conf.d/wordpress.conf 
server {
	listen 80;
	server_name linux.wps.cluster.local.com;
	root /www/wordpress;
	location / {
		index index.php;
	}
	location ~* \.php$ {
		fastcgi_pass 127.0.0.1:9000;
		fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
		include fastcgi_params;
	}
}

[root@web01 ~]# vim /etc/nginx/conf.d/wecenter.conf 
server {
        listen 80;
        server_name linux.wecenter.cluster.local.com;
        root /www/zhihu;
        
        location / {
                index index.php;
        }
        location ~* \.php$ {
                fastcgi_pass 127.0.0.1:9000;
                fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
                include fastcgi_params;
        }
}


# 重启
[root@web01 ~]# systemctl restart nginx

# 创建wordpress数据库
MariaDB [(none)]> create database wordpress;
Query OK, 1 row affected (0.00 sec)
MariaDB [(none)]> create database wecenter;

9. 添加nginx访问认证模块

[root@web01 ~]# htpasswd -c /etc/nginx/conf.d/auth_basic linux  #创建用户并存密码
[root@web01 ~]# vim /etc/nginx/conf.d/wordpress.conf        #配置访问登录
server {
	listen 80;
	server_name linux.wps.cluster.local.com;
	root /www/wordpress;
	client_max_body_size 10m;
	
	location / {
		index index.php;
	}
	location ~* \.php$ {
		fastcgi_pass 127.0.0.1:9000;
		fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
		include fastcgi_params;
	}
	location =/wp-admin {
		auth_basic "please input password!";
		auth_basic_user_file /etc/nginx/conf.d/auth_basic;
		index index.php;
	}
}

10.数据备份与同步
