前言

此处坑多：主要就是用户权限问题
解决方案：自己找吧
Nginx的rpm或源码安装请参考：LNMP搭建

1.环境准备

1.模板下载

此次目录需要三个网站模板
分别是
1.DedeCMS
下载点击此处
2.Discuz
下载点击此处
3.wordpress
下载点击此处

#dedecms
wget http://updatenew.dedecms.com/base-v57/package/DedeCMS-V5.7-UTF8-SP2.tar.gz
#discuz
wget http://download.comsenz.com/DiscuzX/3.3/Discuz_X3.3_SC_UTF8.zip
#wordpress
wget https://cn.wordpress.org/wordpress-4.7.3-zh_CN.tar.gz

2.模板部署

dedecms

mkdir /application/nginx/html/{www,bbs,blog} -p
tar xf DedeCMS-V5.7-UTF8-SP2.tar.gz
cd DedeCMS-V5.7-UTF8-SP2
mv docs/* /application/nginx/html/www/
\mv uploads/* /application/nginx/html/www/

discuz

unzip Discuz_X3.3_SC_UTF8.zip -d /application/nginx/html/bbs/
cd /application/nginx/html/bbs/
ls

wordpress

tar xf wordpress-4.7.3-zh_CN.tar.gz -C /application/nginx/html/blog/

3.修改配置文件

nginx.conf

mkdir /application/nginx/conf/extra
vi /application/nginx/conf/nginx.conf

worker_processes  1;
events {
    worker_connections  1024;
}
http {
log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                  '$status $body_bytes_sent "$http_referer" '
                  '"$http_user_agent" "$http_x_forwarded_for"';

    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    keepalive_timeout  65;
include extra/www.conf;
include extra/bbs.conf;
include extra/blog.conf;
include extra/status.conf;

}

三个站点目录配置文件

cd /application/nginx/conf/extra/

www.conf

    server {
        listen       80;
        server_name  www.etiantian.org;
        location / { 
            root   html/www;
            index  index.php index.html index.htm;
        }   
        location ~ .*\.(php|php5)?$ {
            root    html/www;
            index  index.php;
            fastcgi_pass   127.0.0.1:9000;
            fastcgi_index  index.php;
            include       fastcgi.conf;
        }   
        
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }   
    access_log  logs/www_access.log  main;
    }

bbs.conf

    server {
        listen       80;
        server_name  bbs.etiantian.org;
        location / {
            root   html/bbs;
            index  index.php index.html index.htm;
        }
        location ~ .*\.(php|php5)?$ {
            root    html/bbs;
            index  index.php;
            fastcgi_pass   127.0.0.1:9000;
            fastcgi_index  index.php;
            include       fastcgi.conf;
        }

        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
        access_log  logs/bbs_access.log  main;
    }

blog.conf

    server {
        listen       80;
        server_name  blog.etiantian.org;
        location / {
            root   html/blog;
            index  index.php index.html index.htm;
        }
        location ~ .*\.(php|php5)?$ {
            root    html/blog;
            index  index.php;
            fastcgi_pass   127.0.0.1:9000;
            fastcgi_index  index.php;
            include       fastcgi.conf;
        }

        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
        access_log  logs/blog_access.log  main;
    }
