MySQL双主+Keepalived部署记录

keepalive官方下载路径：http://keepalived.org/download.html

复制链接，下载当前最新版本

wget http://keepalived.org/software/keepalived-2.0.2.tar.gz

tar -xf keepalived-2.0.2.tar.gz

cd keepalived-2.0.2

#指定路径为/usr/local/keepalived

mkdir -p /usr/local/keepalived

#执行configure

报错1

configure: error: no acceptable C compiler found in $PATH

这是因为gcc没有安装：yum install gcc -y

报错2

!!! OpenSSL is not properly installed on your system. !!!

对openssl进行安装：yum install openssl openssl-devel -y

configure完成后，执行

make && make install

修改环境变量

echo "export PATH=\$PATH:/usr/local/keepalived/sbin" >> /etc/profile

（如果系统里本来有keepalive了，那么需要把keepalive的路径写到$PATH前面，否则不会默认调用新安装的keepalived）

#部署py脚本

rpm -ivh http://mirrors.ustc.edu.cn/epel/6/x86_64/epel-release-6-8.noarch.rpm

yum install -y MySQL-python （MySQL一定要注意大小写，否则该语句无法执行成功）
