【Discuz和workpress部署】

# cd /var/www/html/

#wget http://download.comsenz.com/DiscuzX/3.1/Discuz_X3.1_SC_UTF8.zip

#wget https://cn.wordpress.org/wordpress-4.9.4-zh_CN.tar.gz

#unzip Discuz_X3.1_SC_UTF8.zip -d Discuz/

[root@localhost Discuz]# mv upload/* .
[root@localhost Discuz]# chmod o+x uc_server/ config/ uc_client/

MariaDB [(none)]> create database DiscuzDB charset=utf8;

MariaDB [(none)]> grant all on DiscuzDB.* to 'discuz'@'%' identified by '123.com';

MariaDB [(none)]> flush privileges

hosts解析：因为要通过域名连接数据库地址，那么我们需要将数据库的IP地址和自定义域名解析

【wordpress网站部署】

#tar zxvf wordpress-4.9.4-zh_CN.tar.gz -C wordpress/

【数据库授权】
MariaDB [(none)]> create database wpsDB charset=utf8;

MariaDB [(none)]> grant all on *.* to 'wpsuser'@'%' identified by '123.com';

MariaDB [(none)]> flush privileges;

host解析：我们将wordpress域名解析到2.157主库ip地址跟后面即可

到此为止，2.157服务器上的两个网站已经全部发布完成，接下来，将该站点上的内容全部同步到2.158上，为后续的负载均衡做准备

 rsync -aP --delete /var/www/html/dz.bxy.net/ root@192.168.2.158:/var/www/html/dz.bxy.net/
rsync -aP --delete /var/www/html/wps.bxy.net/ root@192.168.2.158:/var/www/html/wps.bxy.net/

同理2.158也需要做本地hosts域名解析

两条命令搞定，2.158只需要将httpp虚机主机搭建起来，配置好与之相同的虚拟主机即可，然后将2.157部署的好网站源码同步过去即可，不需要重新解压~
