社交网站部署——案例扩展

案例扩展

公司社交网站上线后，上级领导对网站运维要求进一步提升，但愿公司网站的可靠性与性能一并提升，要求使用keepalived对Nginx服务器作热备，VIP地址采用192.168.43.10。对Nginx服务器进行性能调优。

keepalived双机热备

一、增长一台服务器搭建Nginx作热备

二、两台Nginx服务器安装keepalived

yum -y install popt-devel kernel-devel openssl-devel gcc gcc-c++         //安装依赖包环境包

tar zxvf keepalived-1.2.13.tar.gz -C /opt
cd /opt/keepalived-1.2.13

./configure --prefix=/  --with-kernel-dir=/usr/src/kernels/2.6.32-431.e16x86_64

make && maek install

chkconfig --add keepalived    //加入到service管理器
chkconfig keepalived on      //开机自启动

三、主Nginx服务器配置

cd /etc/keepalived/
cp keepalived.conf keepalived.conf.bak
vim keepalived.conf

global_defs {
   notification_email {
     acassen@firewall.loc
     failover@firewall.loc
     sysadmin@firewall.loc
   }
   notification_email_from Alexandre.Cassen@firewall.loc
   smtp_server 127.0.0.1
   smtp_connect_timeout 30
   router_id LVS_01               //修改服务器名称//
}

vrrp_instance VI_1 {
    state MASTER                  //主服务器类型//
    interface ens33
    virtual_router_id 10           //VRRP组号//
    priority 100                   //优先级，备份Nginx服务器低于主//
    advert_int 1
    authentication {
        auth_type PASS
        auth_pass 123456
    }
    virtual_ipaddress {
        192.168.43.10             //VIP//
    }
}

service keepalived start       //开启keepalived

ip addr show dev eth0            //可查看VIP，ipconfig看不到//

四、备Nginx服务器配置

global_defs {
   notification_email {
     acassen@firewall.loc
     failover@firewall.loc
     sysadmin@firewall.loc
   }
   notification_email_from Alexandre.Cassen@firewall.loc
   smtp_server 127.0.0.1
   smtp_connect_timeout 30
   router_id LVS_02                   //修改服务器名称//
}

vrrp_instance VI_1 {
    state BACKUP                    //修改服务器类型//
    interface ens33
    virtual_router_id 10
    priority 99                     //修改优先级//
    advert_int 1
    authentication {
        auth_type PASS
        auth_pass 123456
    }
    virtual_ipaddress {
        192.168.43.10                //VIP
    }
}

service keepalived start       //开启keepalived

ip addr show dev eth0            //可查看VIP，ipconfig看不到//
