PHP7

编译安装php-7.3.8

yum install -y freetype-devel libevent libevent-devel libxml2 libxml2-devel ncurses ncurses-devel  openssl openssl-devel  libjpeg libjpeg-devel libpng libpng–devel zlib-devel  bzip2 bzip2-devel libmcrypt libmcrypt-devel curl-devel libxslt libxslt-devel
#yum安装libzip版本低，需要手动编译安装；又依赖于cmake，同样版本低需要手动编译安装

WordPress

中文最新版 wordpress-5.3.2-zh_CN.tar.gz, 需要依赖于高版本PHP

# 创建软链接
ln -s /usr/local/nginx/html/wordpress/ /root/wordpress_ln

# 配置mysql连接信息
cd /usr/local/nginx/html/wordpress/
mv wp-config-sample.php wp-config.php
vi wp-config.php

# 初始化wordpress
http://{Public IP}/wp-admin/install.php

wordpress主题优化

  1. 显示无文章的分类 
    在当前应用主题下的functions.php里添加
add_filter( 'widget_categories_args', 'wpdx_show_empty_cats' );
function wpdx_show_empty_cats($cat_args) {
  $cat_args['hide_empty'] = 0;
  return $cat_args;
}

迁移

注意事项

# 更改mysql连接信息
vi /usr/local/nginx/html/wordpress/wp-config.php
###重点修改
define( 'DB_HOST', '{Private IP}:{Database port}' );
###

#解压带绝对路径的Nginx压缩包
tar -zxPf {nginx}.tar.gz

#自行切换nossl和ssl配置文件
cd /usr/local/nginx/conf/conf.d/
###nossl需要修改server_name
server_name {Public IP}
###

#导入mysql dump数据
mysql -uroot -p wordpress_db --socket=/home/mysqldb/db0/mysql.sock < {mysql}.dump

# mysql常用命令
show databases;
use wordpress_db;
show tables;
select * from {table_name} limit 0,10;
