mysql-MHA预发布环境架构分享(二)之mysql源码安装
安装mysql源码包：(1).安装cmake
（mysql5.5以后是通过cmake来编译的）
下载解压cmake-2.8.5.tar.gz
tar zxf cmake-2.8.12.2.tar.gz -C /usr/local/src
cd /usr/local/src/cmake-2.8.12.2
./configure --prefix=/usr/local/cmake
make && make install
export PATH=/usr/local/cmake/bin:$PATH
【必须依赖包】
cmake make gcc ncurses-devel gcc-c++
(2).安装mysql
groupadd mysql
useradd -s /sbin/nologin -g mysql mysql
cd /app/mysql_soft
tar xf mysql-5.6.17.tar.gz
cd mysql-5.6.17

chkconfig --add mysql
chkconfig mysql on
service mysql start
ln -s /app/mysql/bin/* /usr/bin/

注意：
如果报：
mysqladmin: connect to server at 'localhost' failed
error: 'Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)'
Check that mysqld is running and that the socket: '/var/lib/mysql/mysql.sock' exists!
增加
socket =/app/mysql/data/mysql.sock
