1：下载安装cmake （mysql5.5以后是通过cmake来编译的）
#http://download.csdn.net/detail/csxuedn/7976005 #wget http://www.cmake.org/files/v2.8/cmake-2.8.5.tar.gz # tar -zxv -f /root/cmake-2.8.4.tar.gz
# cd cmake-2.8.4
#./configure
Error when bootstrapping CMake:
Cannot find appropriate C++ compiler on this system.
Please specify one using environment variable CXX.
See cmake_bootstrap.log for compilers attempted. #yum install gcc-c++ #./configure
# make && make install
2：创建mysql的安装目录及数据库存放目录
#mkdir -p /gechong/mysql //安装mysql
#mkdir -p /gechong/mysql/data //存放数据库
3：创建mysql用户及用户组
#groupadd mysql
#useradd -g mysql -s /bin/false -M mysql
4：安装mysql
#wget http://cdn.mysql.com/Downloads/MySQL-5.6/mysql-5.6.21.tar.gz
[root@10-4-5-9 gechong]# ls
mysql
[root@10-4-5-9 gechong]# pwd
/gechong
[root@10-4-5-9 gechong]# tar -zxv -f /root/mysql-5.6.21.tar.gz
[root@10-4-5-9 gechong]# cd mysql-5.6.21/
编译：
cmake . \
-DCMAKE_INSTALL_PREFIX=/gechong/mysql \
-DMYSQL_DATADIR=/gechong/mysql/data \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci \
-DEXTRA_CHARSETS=all \
-DENABLED_LOCAL_INFILE=1
报错了：
CMake Error at cmake/readline.cmake:85 (MESSAGE):
Curses library not found. Please install appropriate package, remove CMakeCache.txt and rerun cmake.On Debian/Ubuntu, package name is libncurses5-dev, on Redhat and derivates it is ncurses-devel.

#yum -y install ncurses-devel
#rm -f CMakeCache.txt
重新编译：
# make clean
# rm -f CMakeCache.txt
# rm -rf /etc/my.cnf
cmake . \

#make && make install
很慢。。。等着吧
5：配置MySQL
# cd /gechong/mysql
# chown -R root:mysql .
# chown -R mysql:mysql data
6：
# cp support-files/my-default.cnf /etc/my.cnf
7：初始化权限表
#scripts/mysql_install_db --user=mysql
8：启动MySQL服务
#ln -s /gechong/mysql/bin/mysql /usr/bin #service mysqld start
10：之后空用户登陆MySQL，删除空用户，对用户赋权限。
