keepalived 安裝與配置

keepalived 官網 .org/ cd /usr/local/src/ wget .org/software/keepalived-1.4 .0.tar

.gz

2, 安裝

tar -zxvf keepalived-1.4 .0.tar .gzcd keepalived-1.4 .0.tar .gz./configure --prefix=/usr/local/keepalived

make && make install

3,將 keepalived 安裝成 linux 系統服務

mkdir /etc/keepalived cp /usr/local/keepalived/etc/keepalived/keepalived.conf /etc/keepalived/

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

4, 修改 keepalived 配置檔案

global_defs ## keepalived會定時執行指令碼並對指令碼執行的結果進行分析,動態調整vrrp_instance的優先順序。 ##如果指令碼執行結果為0,並且weight配置的值大於0,則優先順序相應的增加。如果指令碼執行結果非0, ##並且weight配置的值小於 0,則優先順序相應的減少。其他情況,維持原本配置的優先順序,即配置檔案中priority對應的值。 vrrp_script chk_nginx vrrp_instance vi_1 # 虛擬ip，兩個節點設定必須一樣。可以設定多個，一行寫乙個 virtual_ipaddress track_script

}

5,新增檢測指令碼

建立檢測指令碼bin編輯

vim /etc/keepalived/nginx_check.sh
chmod +x /etc/keepalived/nginx_check.sh
#!/bin/bash
a=`ps -c nginx --no-header | wc -l`
if [ $a
-eq0 ];then
docker start keep_nginx  # docker啟動nginx容器
sleep 2
if [ `ps -c nginx --no-header | wc -l` -eq
0 ];then
killall keepalived
fifi

6,啟動keepalived
