准备CentOS yum源，编译环境，各种源码包
1，编译和源码包准备
gcc环境和源码包下载（所有的源码包都放在/usr/local/src目录下）
yum update
yum groupinstall -y "Development Libraries" "Development Tools"

添加mysql环境变量
vim /etc/profile 添加PATH=$PATH:/usr/local/mysql/bin并重读环境变量
source /etc/profile
添加mysql的库文件
vim /etc/ld.so.conf.d/mysql.cnf 添加/usr/local/mysql/lib这一行代码并重新加载库文件
ldconfig -v
初始化mysql，设置sv启动mysql和mysql的配置文件
/usr/local/mysql/scripts/mysql_install_db --basedir=/usr/local/mysql --datadir=/data/3306/mysql/ --user=mysql
ln -sv /usr/local/mysql/include /usr/include/mysql
mkdir -p /data/3306/mysql/data/

# Example MySQL config file for large systems.
#
# This is for a large system with memory = 512M where the system runs mainly
# MySQL.
#
# MySQL programs look for option files in a set of
# locations which depend on the deployment platform.
# You can copy this option file to one of those
# locations. For information about these locations, see:
#
#
# In this file, you can use all long options that a program supports.
# If you want to know which options a program supports, run the program
# with the "--help" option.
# The following options will be passed to all MySQL clients
