#另外一种安装方式
[root@web01 opt]# rz -E
-rw-r--r-- 1 root root 19889622 Apr 28 21:56 php.tar(2).gz
[root@web01 opt]# tar xf php.tar\(2\).gz
[root@web01 opt]# yum localinstall -y *.rpm
# 修改配置文件
[root@web01 ~]# vim /etc/php-fpm.d/www.conf 
user = www

7、将web02和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

[root@web03 ~]# mkdir /www
[root@web03 ~]# chown -R www.www /www/
[root@web03 ~]# mount  -t nfs 172.16.1.31:/nfs/web /www
[root@web03 ~]# mount -t nfs 172.16.1.31:/nfs/conf /etc/nginx/conf.d/
[root@web03 ~]# systemctl restart nginx

8、搭建wordpress

# 共享代码、共享数据、共享nginx配置

注：web01机器操作

[root@web01 ~]# groupadd www -g888
[root@web01 ~]# useradd www -u 888 -g 888 -s /sbin/nologin -M
[root@web01 ~]# mkdir /www
[root@web01 ~]# cd /www/
[root@web01 www]# rz -E
[root@web01 www]# ll
-rw-r--r-- 1 root root 11098483 Apr 29 11:27 wordpress.tar.gz
[root@web01 www]# tar -xf wordpress.tar.gz 
drwxr-xr-x 5 1006 1006     4096 Jan 11  2019 wordpress
-rw-r--r-- 1 root root 11098483 Apr 29 11:27 wordpress.tar.gz
[root@web01 www]# chown -R www.www /www/

[root@web01 www]# cd /etc/nginx/conf.d/
[root@web01 conf.d]# ll
-rw-r--r-- 1 root root 1072 Apr 21 00:07 default.conf
[root@web01 conf.d]# rm -rf default.conf 



## 在nfs服务器上创建/nfs/conf目录
[root@nfs web]# mkdir /nfs/conf

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

## 加入nfs配置文件
[root@nfs web]# vim /etc/exports
/nfs/web      172.16.1.0/24(rw,sync,all_squash,anonuid=888,anongid=888)
/nfs/database 172.16.1.0/24(rw,sync,all_squash,anonuid=888,anongid=888)
/nfs/download 172.16.1.0/24(rw,sync,all_squash,anonuid=888,anongid=888)
/nfs/conf     172.16.1.0/24(rw,sync,all_squash,anonuid=888,anongid=888)

#查看
[root@nfs web]# showmount -e
Export list for nfs:
/nfs/conf     172.16.1.0/24
/nfs/download 172.16.1.0/24
/nfs/database 172.16.1.0/24
/nfs/web      172.16.1.0/24

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


注：在web01机器执行
## 挂载到web服务器
[root@web01 conf.d]# mount -t nfs 172.16.1.31:/nfs/conf /etc/nginx/conf.d/

## 增加wordpress配置
[root@web01 conf.d]# vim 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;
	}
}

# 重启
[root@web01 conf.d]# systemctl restart nginx

# 创建wordpress数据库
[root@db01 ~]# mysql -uroot -p123
MariaDB [(none)]> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| mysql              |
| performance_schema |
| test               |
+--------------------+
4 rows in set (0.01 sec)

MariaDB [(none)]> create database wordpress;
Query OK, 1 row affected (0.00 sec)

[root@db01 ~]# systemctl restart mariadb



访问  可以配域名访问   加入hosts文件
172.16.1.51  linux.wps.cluster.local.com

8-1上传主题

8-2报错413修改web01配置文件

[root@web01 opt]# vim /etc/nginx/conf.d/wordpress.conf 
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;
        }
}

[root@web01 opt]# nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
[root@web01 opt]# systemctl restart nginx


# web02和web03重启就可以了
[root@web02~]# systemctl restart nginx

9、搭建WeCenter

[root@web01 ~]# rz -E
-rw-r--r--  1 root root 25744989 Apr 28 17:35 zhihu.zip
[root@web01 www]# unzip zhihu.zip 
[root@web01 www]# mv zhihu /www/
[root@web01 www]# cd /www
[root@web01 www]# chown www.www -R zhihu/
[root@web01 www]# 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;
        }
}

# 三台都重启
[root@web01 conf.d]# systemctl restart nginx

#解析域名
192.168.15.7 linux.wecenter.cluster.local.com

# 创建wordpress数据库
[root@db01 ~]# mysql -uroot -p123

MariaDB [(none)]> create database wecenter;
Query OK, 1 row affected (0.00 sec)

MariaDB [(none)]> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| mysql              |
| performance_schema |
| test               |
| wecenter           |
| wordpress          |
+--------------------+
6 rows in set (0.00 sec)

10、数据库备份

[root@db01 databases]# groupadd www -g888
[root@db01 databases]# useradd www -u 888 -g 888 -s /sbin/nologin -M
[root@db01 databases]# chown www.www /databases/
[root@db01 databases]# mount -t nfs 172.16.1.31:/nfs/database /databases/
[root@db01 ~]# chmod +x mysql_dump.sh 
[root@db01 ~]# ./mysql_dump.sh 
# 编写备份脚本
[root@db01 ~]# cat 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 ~]# ll /databases/
total 396
-rw-r--r-- 1 www www 398455 Apr 29 22:38 mysql-all-2021-04-29.tar.gz
-rw-r--r-- 1 www www    228 Apr 29 22:36 mysql_dump.sh

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

11、后台加密码

[root@web01 www]# htpasswd -c /etc/nginx/conf.d/auth_basic linux
[root@web01 conf.d]# wordpress.conf
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;
	}
}

12、web网站的实时备份
