1 # wget http://www.keepalived.org/software/keepalived-1.3.6.tar.gz2 # tar -zvxf keepalived-1.3.6.tar.gz -C /tmp/3 # cd /tmp/keepalived-1.3.64 # ./configure --prefix=/usr/local/keepalived/ --sysconf=/etc --with-init=SYSV5 #注：(upstart|systemd|SYSV|SUSE|openrc) #根据你的系统选择对应的启动方式6 # make && make install7 # ln -s /usr/local/keepalived/sbin/keepalived /sbin8 # chmod u+x /etc/init.d/keepalived9 # chkconfig --add keepalived 10 # chkconfig --level 35 keepalived onhttps://common.cnblogs.com/images/copycode.gif
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。https://img2018.cnblogs.com/blog/680719/201811/680719-20181105120734326-927708711.png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。https://common.cnblogs.com/images/copycode.gif
