四安装Keepalived4.1 下载[url=]

[/url]
1 [root@Master01 ~]# wget http://www.keepalived.org/software/keepalived-1.3.6.tar.gz 2 [root@Master01 ~]# tar -zvxf keepalived-1.3.6.tar.gz -C /tmp/ 3 [root@Master01 ~]# cd /tmp/keepalived-1.3.6 4 [root@Master01 keepalived-1.3.6]# ./configure --prefix=/usr/local/keepalived/ --sysconf=/etc --with-init=SYSV 5 #注：(upstart|systemd|SYSV|SUSE|openrc) #根据你的系统选择对应的启动方式 6 [root@Master01 keepalived-1.3.6]# make && make install 7 [root@Master01 ~]# ln -s /usr/local/keepalived/sbin/keepalived /sbin 8 [root@Master01 ~]# chmod u+x /etc/init.d/keepalived 9 [root@Master01 ~]# chkconfig --add keepalived 10 [root@Master01 ~]# chkconfig --level 35 keepalived on[url=]

注意：Master02上也需要如上操作。

若出现以下提示，需要执行：yum -y install openssl-devel。

提示：也可采用yum install -y keepalived安装（个人不建议）。

4.2 Master01配置Keepalived

默认情况下keepalived启动时会去/etc/keepalived目录下找配置文件。
