KeepAlived 安装

Posted 2021-01-20 littlewrong

yum install -y gcc gcc-c++ openssl openssl-devel

目前keepalived最新版本下载：
[[email protected] ~]#wget -c http://www.keepalived.org/software/keepalived-1.2.12.tar.gz
[[email protected] ~]# tar zxvf keepalived-1.2.12.tar.gz
[[email protected] ~]# cd keepalived-1.2.12
安装编译环境：
[[email protected] ~]# yum install -y gcc gcc-c++ openssl openssl-devel
1

[[email protected] keepalived-1.2.12]# ./configure --prefix=/usr/local/keepalived //指定安装路径

[[email protected] keepalived-1.2.12]# make && make install //安装
将keepalived命令软连接到/usr/bin下
[[email protected] keepalived-1.2.12]# ln -s /usr/local/keepalived/sbin/keepalived /usr/bin/keepalived

添加启动脚本且方便用service keepalived start/stop/restart管理(如果没有init.d/keepalived则从源码目录拷贝)
[[email protected] keepalived-1.2.12]# cp /usr/local/keepalived/etc/rc.d/init.d/keepalived /etc/init.d/keepalived
[[email protected] keepalived-1.2.12]# chmod 755 /etc/init.d/keepalived //添加执行权限
[[email protected] keepalived-1.2.12]# chkconfig keepalived on //开机启动

修改/etc/init.d/keepalived中的程序路径
# Source configuration file (we set KEEPALIVED_OPTIONS there)
. /etc/sysconfig/keepalived

改为：
# Source configuration file (we set KEEPALIVED_OPTIONS there)
. /usr/local/keepalived/etc/sysconfig/keepalived

默认情况下，keepalived 会读取 /etc/keepalived 下keepalived.conf 文件
如果没有建立这个文件，keepalived也不会报错，但是会发现，所创建的关于keepalived的相关参数根本就没有生效。
[[email protected] keepalived-1.2.12]# mkdir /etc/keepalived
[[email protected] keepalived-1.2.12]# ln -s /usr/local/keepalived/etc/keepalived/keepalived.conf /etc/keepalived/keepalived.conf

启动测试：
[[email protected] keepalived-1.2.12]# service keepalived restart
停止 keepalived： [确定]
启动 keepalived： [确定]

安装完成

service keepalived restart
service keepalived stop
service keepalived start

systemctl start keepalived
systemctl restart keepalived
systemctl stop keepalived
