Keepalived安装与配置

---

 

下载并解压Keepalived安装包到两台nginx所在的服务器

 

• 192.168.200.1

 

• 192.168.200.2

 

 

执行编译安装（安装目录设置为 /usr/local/keepalived ）

 

./configure --prefix=/usr/local/keepalived && make && make install

 

 

修改keepalived运行环境

 

• 将keepalived启动命令软连接到/usr/bin下

 

          ln -s /usr/local/keepalived/sbin/keepalived /usr/bin/keepalived

 

• 拷贝配置文件到Keepalived需要的目录

 

          /usr/local/keepalived/etc/keepalived/keepalived.conf /etc/keepalived/keepalived.conf

 

 

配置Keepalived，整合nginx（仅保留默认配置文件中的以下部分，并修改红色部分）

 

global_defs {

  notification_email {

  #acassen@firewall.loc

  #failover@firewall.loc

  #sysadmin@firewall.loc

  }

  #notification_email_from Alexandre.Cassen@firewall.loc

  #smtp_server 192.168.200.1

  #smtp_connect_timeout 30

  router_id node1（备机这里为node2）

}

vrrp_instance VI_1 {

  state MASTER（ 备机为BACKUP ）

  interface eth0

  virtual_router_id 51

mcast_src_ip 192.168.200.1（备机为192.168.200.2）

  priority 100（备机为99）

  advert_int 1

  authentication {

  auth_type PASS

  auth_pass 1111

  }

  virtual_ipaddress {

  10.135.102.88（主备机这里都一样）

  }

}

 

 

启动/停止Keepalived

 

• /usr/bin/keepalived（手工启动）

 

• kill -9 keepalived_pid（强行停止）
