在mysql5.6的版本以后，配置与mysql5.5版本相比发生了细小的变化，下面就以mysql-5.6.23来编译，实验环境为CentOS6.6。

一，准备工作
先下载所需的安装包mysql-5.6.23-linux-glibc2.5-i686 ，下载地址 http://mirrors.sohu.com/mysql/MySQL-5.5/ 

编译安装的目录：/usr/local/

二，编译安装

1、准备数据存放的文件系统，与上次编译时的做法相同。

新建一个逻辑卷，并将其挂载至特定目录即可。这里创建逻辑卷的挂载目录为/mydata，而后创建/mydata/data目录做为mysql数据的存放目录。创建逻辑卷是为了方便数据的备份及转移，设置数据存放目录的大小。

<code>
[root@www ~]# fdisk /dev/sdb

[root@www ~]# partprobe /dev/sdb

</code>

2、新建系统用户以其运行进程：

<code>
[root@www mysql]# groupdel mysql
[root@www mysql]# groupadd -r -g 306 mysql
[root@www mysql]# useradd -r -g 306 -u  306  mysql
[root@www mysql]# id  mysql
uid=306(mysql) gid=306(mysql) groups=306(mysql)
</code>

3、安装并初始化mysql-5.6.23

<code>
[root@www ~]# tar xf mysql-5.6.23-linux-glibc2.5-i686.tar.gz -C /usr/local
[root@www ~]# cd /usr/local/
[root@www ~]# ln -sv mysql-5.6.23-linux-glibc2.5-i686  mysql
[root@www ~]# cd mysql 

[root@www ~]# chown -R mysql:mysql  .   
[root@www ~]# scripts/mysql_install_db --user=mysql --datadir=/mydata/data   
[root@www ~]# chown -R root  .
</code>

4、为mysql提供主配置文件

5.6与5.5的不同主要在此。

执行第三步后，会在mysql目录下创建my.cnf文件。
执行# scripts/mysql_install_db –user=mysql –datadir=/mydata/data 以前mysql目录下的文件：

<code>
[root@localhost mysql]# ls
bin      data  include         lib  mysql-test  scripts  sql-bench
COPYING  docs  INSTALL-BINARY  man  README      share    support-files
</code>

执行后的文件：

<code>
[root@localhost mysql]# ls
bin      data  include         lib  my.cnf      README   share      support-files
COPYING  docs  INSTALL-BINARY  man  mysql-test  scripts  sql-bench
</code>

mysql5.6.10以后的版本不需要复制文件

<code>
[root@localhost mysql]# cp support-files/my-large.cnf  /etc/my.cnf
</code>

文件夹中有my.cnf 文件，只需修改此文件即可，也可以将support-files/my-default.cnf 文件复制过去，
但需要将文件的data选项和socket选项启用。

<code>
[root@localhost mysql]# vim my.cnf 
# These are commonly set, remove the # and set as required.
# basedir = .....
 datadir = /mydata/data
# port = .....
# server_id = .....
socket = /tmp/mysql.sock
</code>

5、修改PATH环境变量，让系统可以直接使用mysql的相关命令。

<code>
[root@www ~]# vim  /etc/profile.d/mysql.sh 
 export PATH=$PATH:/usr/local/mysql/bin/   ------>创建此文件添加此行
</code>

6、为mysql提供sys v服务脚本：

<code>
[root@www ~]# cd /usr/local/mysql
[root@www mysql]# cp support-files/mysql.server  /etc/init.d/mysqld
[root@www mysql]# chmod +x /etc/init.d/mysqld
</code>

添加至服务列表：

<code>
[root@www mysql]# chkconfig --add mysqld
[root@www mysql]# chkconfig mysqld on
</code>

而后就可以启动服务测试使用了。

三，测试结果

此处不需要将mysqld服务添加到chkconfig中，默认已经添加了。

<code>
[root@localhost ~]# service mysqld  start
Starting MySQL...................................... SUCCESS! 
[root@localhost bin]# mysql
Welcome to the MySQL monitor.  Commands end with ; or \g.
