centos 7 源代码安装mysql5.6

###### mysql #########

引言:这里选用mysql5.6版本，5.7版本编译时间需要几个小时。

编译安装环境:

yum -y install make gcc-c++ cmake bison-devel ncurses-devel gcc\
autoconf automake zlib* fiex* libxml* libmcrypt* libtool-ltdl-devel*

下载mysql5.6
wget http://dev.mysql.com/get/Downloads/MySQL-5.6/mysql-5.6.16.tar.gz

# Preconfiguration setup
shell> groupadd mysql
shell> useradd -r -g mysql -s /bin/false mysql

# Beginning of source-build specific instructions
shell> tar xvf mysql-5.6.16.tar.gz
shell> cd mysql-5.6.16
shell> mkdir bld
shell> cd bld
shell> cmake ..
若出错
make clean
rm -f CMakeCache.txt
看到最后输出:Build files have been written to:xxxxxxx证明编译成功
shell> make
shell> make install
