【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/
[[email protected] Discuz]# mv upload/* .
[[email protected] 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：因為要通過域名連線資料庫地址，那麼我們需要將資料庫的IP地址和自定義域名解析
【wordpress網站部署】
#tar zxvf wordpress-4.9.4-zh_CN.tar.gz -C wordpress/
【資料庫授權】
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：我們將wordpress域名解析到2.157主庫ip地址跟後面即可

到此為止，2.157伺服器上的兩個網站已經全部發布完成，接下來，將該站點上的內容全部同步到2.158上，為後續的負載均衡做準備
rsync -aP --delete /var/www/html/dz.bxy.net/ [email protected]:/var/www/html/dz.bxy.net/
rsync -aP --delete /var/www/html/wps.bxy.net/ [email protected]:/var/www/html/wps.bxy.net/
同理2.158也需要做本地hosts域名解析
兩條命令搞定，2.158只需要將httpp虛機主機搭建起來，配置好與之相同的虛擬主機即可，然後將2.157部署的好網站原始碼同步過去即可，不需要重新解壓~
