keepalived安装配置

1.环境配置

ln -s /usr/src/kernels/2.6.32-573.26.1.el6.x86_64/ /usr/src/linux

如果/usr/src/kernels/下没有东西，先安装kernel-devel（yum install kernel-devel）

2.两台linux按安装keepalived

tar -zxvf keepalived-1.2.19.tar.gz
./configure
make 
make install
echo $?

cp /usr/local/etc/rc.d/init.d/keepalived /etc/init.d/
cp /usr/local/etc/sysconfig/keepalived /etc/sysconfig/
mkdir /etc/keepalived
cp /usr/local/etc/keepalived/keepalived.conf  /etc/keepalived/
cp /usr/local/sbin/keepalived /usr/bin/

/etc/init.d/keepalived start
ps -ef|grep keep

3.修改配置文件

主节点：

备节点：

4.测试

5.多实例设置

6.日志设置（keepalived日志默认在/var/log/messages里面）：

设置keepalived使其生成一个独立的日志文件：

vim /etc/sysconfig/keepalived
#KEEPALIVED_OPTIONS="-D"
KEEPALIVED_OPTIONS="-D -S 0 -d"


vim /etc/rsyslog.conf 
#keepalived log
local0.*                                                /var/log/keepalived.log

[root@server05 ~]# /etc/init.d/rsyslog restart
