192.168.2.157站點

【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：因爲要通過域名連接數據庫地址，那麼我們需要將數據庫的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/

【數據庫授權】
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

到此爲止，2.157服務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，爲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部署的好網站源碼同步過去即可，不需要重新解壓~
