ubuntu重新安装workpress

需求

阿里云环境更新新版本wordpress后，发现主题不兼容，想要将wordpress 6.4.3调整为wordpress 5.2.3

环境：
1. 阿里云ECS ubuntu_16_0402_64
2. nginx+php7.0+mysql

下载wordpress

下载需要的wordpress版本，然后解压出wordpress目录，将该目录上传为ubuntu网站目录var/www/wordpress

nginx配置

找到/etc/nginx/目录

打开sites-enabled/default文件找到

# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000

然后将下方的注释去掉，开启php代码解析

location ~ \.php$ {
    include snippets/fastcgi-php.conf;

    # With php7.0-cgi alone:
#   fastcgi_pass 127.0.0.1:9000;
#   # With php7.0-fpm:
    fastcgi_pass unix:/run/php/php7.0-fpm.sock;
}

然后找到

# You can move that to a different file under sites-available/ and symlink that
# to sites-enabled/ to enable it.

将下方注释去掉，然后配置站点信息

server {
    listen 80;
    listen [::]:80;

    server_name teachcourse.cn;

    root /var/www/wordpress;
    index index.html index.php;

    location / {
        try_files $uri $uri/ =404;
    }

浏览器服务

浏览器输入localhost/wordpress，提示安装界面

按照提示，输入：Database Name、Username、Password、Database Host、Table Prefix

自动生成wp-config.php

上一步作用是生成wp-config.php文件，也可以直接复制已有的文件到wordpress站点根目录下
