实现同台服务器同时运行WORDPRESS与DISCOURSE

简思录站点就是通过一台服务器同时运行WordPress和Discourse项目的。今天是简思录搭建成功上线的第二天，刚好有时间，顺便整理一下如何部署这两个项目，同时也希望能帮到一些需要的站长们！要实现同一台服务器同时运行WordPress和Discourse有2种方式，一种是全新安装（即服务器上并没有运行WordPress和Discourse的项目），另一种则是已经有Discourse项目运行着了。

这里就说说全新安装方式：

服务器配置清单

简思录站点服务器托管在Qcloud。购于2017年10月26号，当时看到双十一广告，一口气买了3年，花费1534.60元，还是挺划算的，需要购买的请猛戳该链接！

Linux Server [2 Core CPU, 4G Memory, 50G Disk, 64 位] - Debian Server 9.0 64 位

WordPress部署

WordPress运行需要LNMP环境（Linux + Nginx+ MySQL+ PHP），这里我们可以采用LNMP一键安装包，推荐OneinStack，官网链接：https://oneinstack.com/

OneinStack安装这里就不详细阐述了，如果不明白安装的可以去OneinStack官网查看安装教程，非常详细。那么下面的步骤我就权当你已经成功运行WordPress了。

Nginx配置

如果是通过oneinstack一键安装包的，Nginx的配置文件路径为：/usr/local/nginx/conf/vhost
进入该目录后，修改你绑定域名的配置文件，参考代码如下：

server {
  listen 80;
  listen 443 ssl http2;
  ssl_certificate /usr/local/nginx/conf/ssl/jiansilu.com.crt;  #修改为你证书的路径
  ssl_certificate_key /usr/local/nginx/conf/ssl/jiansilu.com.key;  #修改为你证书的路径
  ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
  ssl_ciphers EECDH+CHACHA20:EECDH+AES128:RSA+AES128:EECDH+AES256:RSA+AES256:EECDH+3DES:RSA+3DES:!MD5;
  ssl_prefer_server_ciphers on;
  ssl_session_timeout 10m;
  ssl_session_cache builtin:1000 shared:SSL:10m;
  ssl_buffer_size 1400;
  add_header Strict-Transport-Security max-age=15768000;
  ssl_stapling on;
  ssl_stapling_verify on;
  server_name jiansilu.com www.jiansilu.com;  #修改为你的域名
  location / {
    access_log /data/wwwlogs/jiansilu.com_nginx.log combined;
    index index.html index.htm index.php;
    root /data/wwwroot/jiansilu.com;  #修改为你站点的目录
    if ($ssl_protocol = "") { return 301 https://$host$request_uri; }
    if ($host != jiansilu.com) {  return 301 $scheme://jiansilu.com$request_uri;  }  #修改为你的域名
    include /usr/local/nginx/conf/rewrite/wordpress.conf;
    #error_page 404 /404.html;
    #error_page 502 /502.html;
  
    location ~ [^/]\.php(/|$) {
        #fastcgi_pass remote_php_ip:9000;
        fastcgi_pass unix:/dev/shm/php-cgi.sock;
        fastcgi_index index.php;
        include fastcgi.conf;
    }

    location ~ .*\.(gif|jpg|jpeg|png|bmp|swf|flv|mp4|ico)$ {
        expires 30d;
        access_log off;
    }
    location ~ .*\.(js|css)?$ {
        expires 7d;
        access_log off;
    }
    location ~ /\.ht {
        deny all;
    }
  }
  location /community/ { # /community/ 为站点子目录名称，例如：https://jiansilu.com/community
    proxy_pass http://unix:/var/discourse/shared/standalone/nginx.http.sock:;
    proxy_set_header Host $http_host;
    proxy_http_version 1.1;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Proto https;
  }
}

然后，执行如下命令：

root@localhost:~# sudo nginx -t # 测试配置文件
# 重要：如果 nginx -t 返回了错误，请一定要修正配置！
root@localhost:~# sudo service nginx reload #加载配置文件
root@localhost:~# sudo service nginx restart #重启nginx

好了，到这里WordPress和Nginx配置就可以了，接下来就可以部署Discourse了。

Discourse部署

运行命令安装docker

root@localhost:~# curl -sSL https://get.docker.com/ | sh

运行命令创建discourse目录与克隆项目，并进入discourse目录

root@localhost:~# sudo -s
root@localhost:~# mkdir /var/discourse
root@localhost:~# git clone https://github.com/discourse/discourse_docker.git /var/discourse
root@localhost:~# cd /var/discourse

创建app.yml配置文件，并上传至/var/discourse/containers ，参考代码如下：

## this is the all-in-one, standalone Discourse Docker container template
##
## After making changes to this file, you MUST rebuild
## /var/discourse/launcher rebuild app
##
## BE *VERY* CAREFUL WHEN EDITING!
## YAML FILES ARE SUPER SUPER SENSITIVE TO MISTAKES IN WHITESPACE OR ALIGNMENT!

       filename: /etc/nginx/conf.d/discourse.conf

  - exec: echo "End of custom commands"

运行命令安装discourse

root@localhost:/var/discourse# ./launcher bootstrap app

安装discourse完成后，运行命令启动discourse

root@localhost:/var/discourse# ./launcher start app

duan~~~,至此就完成WordPress和Discourse同时运行在一个服务器了。
