Nginx反向代理三台服务器共用一台nfs

安装Nginx配置反向代理

安装方式：

yum install epel-relase
yum install nginx         //epel方式安装
./configure --prefix=/usr/local/nginx --without-http_write_module       //编译安装

启动方式：

/usr/local/nginx/sbin/nginx -c /usr/lcoal/nginx/conf/nginx.conf
/usr/local/nginx/sbin/nginx -s reload

nginx负载均衡：

1. 基于轮询：

   http{
       upstream myweb{
           server 10.0.0.10;
           server 10.0.0.11;
           server 10.0.0.12;
   }
       server{
           listen 80;
           location /{
               proxy_pass http://myweb;
           }
       }
   }
   

2. 基于权重

   http{
       upstream myweb{
           server 10.0.0.10 weight=2;
           server 10.0.0.11 weight=1;
           server 10.0.0.12 weight=3;
   }
       server{
           listen 80;
           location /{
               proxy_pass http://myweb;
           }
       }
   }
   

3. 基于IP

[root@bogon home]# cat 1.conf

    http{
        upstream myweb{
            ip_hash;
            server 10.0.0.10;
            server 10.0.0.11;
            server 10.0.0.12;
    }
        server{
            listen 80;
            location /{
                proxy_pass http://myweb;
            }
        }
    }

安装NFS存储服务

1. 服务端

   yum install rpcbind nfs-utils -y
   

2. 服务端配置文件

   /etc/exports
   

   

   /share 192.168.1.102/24(rw,sync,fsid=0)
   

   

3. 服务端产看

   showmount *     //查看自己共享的服务
   rpcinfo
   exports
   showmount -a //显示已经与客户端连接上的目录信息
   systemctl start rpcbind.service
   systemctl start nfs-server.service
   

4. 客户端

   yum install rpcbind nfs-utils -y
   systemctl enable rpcbind.service && systemctl start rpcbind.service
   show mount -e NFS服务器IP  //检查服务器是否有共享目录
   

5. 挂载服务器

   mount -t nfs 192.168.16.107:/share /var/www/html/
   

crontab 定时任务

编写日志切割脚本，结合计划任务，每天凌晨两点，自动备份并切割nginx的访问日志

/usr/sbin/logrotate -f /etc/logrotate.d/nginx
mv /mnt/nginxaccess.log.1  /mnt/`date +%y%m%d`.log
tar vczf /mnt/`date +%y%m%d`.access.tar.gz  /mnt/`date +%y%m%d`.log
rm `date +%y%m%d`.log

Crontab

2 0 * * * /usr/sbin/logrotate -f /etc/logrotate.d/nginx
2 0 * * *  /247/myscript/tar_nginxlog.sh
