Keepalived部署雙主熱備

二、配置keepalived主和從

2.2、配置keepalived - 從

2.3、啟動keepalived

三、keepalived註冊為系統服務

四、keepalived配置nginx自動重啟

五、配置keepalived雙主熱備

# 上傳壓縮包 scp ./keppalived.tar.gz [email protected]:/home/software # 解壓

tar -zxvf keppalived.tar.gz

./configure --prefix=/usr/local/keepalived --sysconf=/etc

警告

make &&make

install

進入/etc/keepalived，該目錄下為keepalived核心配置檔案

2.1.1、通過命令vim keepalived.conf開啟配置檔案，檔案位置/etc/keepalived資料夾下

global_defs # 計算機節點 vrrp_instance vi_1 virtual_ipaddress

}

ip addr 命令可以檢視自己的ip和網絡卡位址

2.1.2、啟動keepalived

# 進去啟動目錄 cd /usr/local/keeplived/sbin # 啟動 ./keepalived # 檢視程序 ps -ef| grep keepalived # 檢視虛擬ip

ip addr

2.2.1、通過命令vim keepalived.conf開啟配置檔案，檔案位置/etc/keepalived資料夾下

global_defs # 計算機節點 vrrp_instance vi_1 virtual_ipaddress

}

ip addr 命令可以檢視自己的ip和網絡卡位址

# 進去啟動目錄 cd /usr/local/keeplived/sbin # 啟動 ./keepalived # 檢視程序 ps -ef| grep keepalived # 檢視虛擬ip

ip addr

# 進入解壓目錄 cd /home/software/keepalived-2.0.18 # 進入keepalived目錄 cd keepalived # 進入etc目錄 cd etc # 拷貝配置檔案到系統etc下的init.d資料夾下 cp init.d/keepalived /etc/init.d/ # 拷貝配置檔案到系統etc下的sysconfig資料夾下 cp sysconfig/keepalived /etc/sysconfig/ # 重新整理配置

systemctl daemon-reload

# 啟動keepalived服務 systemctl start keepalived.service # 檢測keepalived服務狀態，兩種方法都可以 systemctl status keepalived.service ps -ef| grep keepalived # 停止keepalived服務 systemctl stop keepalived.service # 重啟keepalived服務

systemctl restart keepalived.service

vim /etc/keepalived/check_nginx_alive_or_not.sh #!/bin/basha=` ps -c nginx --no-header | wc -l` # 判斷nginx是否宕機，如果宕機了，嘗試重啟if[ $a -eq 0 ] ;then /usr/local/nginx/sbin/nginx # 等待一小會再次檢查nginx，如果沒有啟動成功，則停止keepalived，使其啟動備用機 sleep 3 if[` ps -c nginx --no-header | wc -l` -eq 0 ] ;then killall keepalived

vrrp_script check_nginx_alive

這段**配置在/etc/keepalived/keepalived.conf指令碼中』

track_script

systemctl restart keepalived

global_defs vrrp_script check_nginx_alive # 計算機節點 vrrp_instance vi_1 track_script virtual_ipaddress

}

vrrp_script check_nginx_alive # 計算機節點 vrrp_instance vi_1 track_script virtual_ipaddress }vrrp_instance vi_2 virtual_ipaddress

}

global_defs # 計算機節點 vrrp_instance vi_1 virtual_ipaddress }vrrp_instance vi_2 virtual_ipaddress

}

systemctl restart keepalived.service
