下载解压wordpress安装包并配置：
## aigc-bot.com这个目录可以自定义名称，可以是你的网站域名或者其他[root@VM-0-12-centos php]# mkdir -p /var/www/html/aigc-bot.com[root@VM-0-12-centos php]# cd /var/www/html/[root@VM-0-12-centos html]# wget https://cn.wordpress.org/latest-zh_CN.tar.gz[root@VM-0-12-centos html]# tar -zxvf latest-zh_CN.tar.gz[root@VM-0-12-centos html]# mv wordpress/ ./aigc-bot.com/[root@VM-0-12-centos html]# ll wordpress/total 0[root@VM-0-12-centos html]# rm -rf wordpress/[root@VM-0-12-centos html]# rm -rf latest-zh_CN.tar.gz[root@VM-0-12-centos html]# cd ./aigc-bot.com/[root@VM-0-12-centos aigc-bot.com]# mv wp-config-sample.php wp-config.php[root@VM-0-12-centos aigc-bot.com]# vim wp-config.php##修正干系数据库配置......// Database settings - You can get this info from your web host /// The name of the database for WordPress /define( 'DB_NAME', 'wp_db' );/ Database username /define( 'DB_USER', 'wpuser' );/ Database password /define( 'DB_PASSWORD', 'wpuser!@#' );/ Database hostname /define( 'DB_HOST', 'localhost' );/ Database charset to use in creating database tables. /define( 'DB_CHARSET', 'utf8mb4' );......
