社交網站部署——案例擴展

案例擴展

公司社交網站上線後，上級領導對網站運維要求進一步提升，但願公司網站的可靠性與性能一併提升，要求使用keepalived對Nginx服務器作熱備，VIP地址採用192.168.43.10。對Nginx服務器進行性能調優。

keepalived雙機熱備

一、增長一臺服務器搭建Nginx作熱備

二、兩臺Nginx服務器安裝keepalived

yum -y install popt-devel kernel-devel openssl-devel gcc gcc-c++         //安裝依賴包環境包

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      //開機自啓動

三、主Nginx服務器配置

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               //修改服務器名稱//
}

vrrp_instance VI_1 {
    state MASTER                  //主服務器類型//
    interface ens33
    virtual_router_id 10           //VRRP組號//
    priority 100                   //優先級，備份Nginx服務器低於主//
    advert_int 1
    authentication {
        auth_type PASS
        auth_pass 123456
    }
    virtual_ipaddress {
        192.168.43.10             //VIP//
    }
}

service keepalived start       //開啓keepalived

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

四、備Nginx服務器配置

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                   //修改服務器名稱//
}

vrrp_instance VI_1 {
    state BACKUP                    //修改服務器類型//
    interface ens33
    virtual_router_id 10
    priority 99                     //修改優先級//
    advert_int 1
    authentication {
        auth_type PASS
        auth_pass 123456
    }
    virtual_ipaddress {
        192.168.43.10                //VIP
    }
}

service keepalived start       //開啓keepalived

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