[root@web01 ~]# vim /etc/nginx/fastcgi_params
...
fastcgi_param HTTPS on;


[root@web01 ~]# vim /etc/nginx/conf.d/wordpress.conf
server {
        listen 80;
        server_name wp.com;
        root /code/wordpress;
        index index.php;

        location ~ \.php {
                fastcgi_pass 127.0.0.1:9000;
                fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

                fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
                include fastcgi_params;
        }

}


# 5.创建站点目录
[root@web01 ~]# mkdir /code/{wordpress,zh} -p

# 6.检查语法
[root@web01 ~]# nginx -t

# 7.重新加载配置文件
[root@web01 ~]# nginx -s reload

# 8.配置域名解析


##### 9.上传wordpress和Wecenter（或者去网站下载）
[root@web01 ~]# rz

# 9.1解压
[root@web01 ~]# tar xf wordpress-5.0.3-zh_CN.tar.gz 
[root@web01 ~]# unzip WeCenter_3-2-1.zip

# 10.把所有文件移动到站点目录下
[root@web01 ~]# mv wordpress/* /code/wordpress/
[root@web01 ~]# mv WeCenter_3-2-1/* /code/zh/

# 11.授权目录
[root@web01 ~]# chown www.www -R /code/

# 12.上传解压主题
[root@web01 ~]# cd /code/wordpress/wp-content/themes
[root@web01 /code/wordpress/wp-content/themes]# rz
[root@web01 /code/wordpress/wp-content/themes]# unzip QQ.zip

3.安装部署mariadb（db01操作）

# 1.下载mariadb
[root@db01 ~]# yum install -y mariadb-server.x86_64 

# 2.启动数据库并开机自启
[root@db01 ~]# systemctl start mariadb.service 
[root@db01 ~]# systemctl enable mariadb.service

# 3.给数据库一个登入密码
[root@db01 ~]# mysqladmin -uroot password ‘123‘

# 4.登入数据库
[root@db01 ~]# mysql -uroot -p123

# 5.创建wordpress和Wecenter数据库
MariaDB [(none)]> create database wp;
MariaDB [(none)]> create database zh;

# 6.查看是否创建成功
MariaDB [(none)]> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| mysql              |
| performance_schema |
| test               |
| wp                 |
| zh                 |
+--------------------+
6 rows in set (0.00 sec)

# 7.创建用户 （所有数据库的登入用户）
MariaDB [(none)]> grant all on *.* to wp_zh@‘%‘ identified by ‘111‘;
