Centos6 源码部署MySQL5.6

不OK就执行以下两行命令（否则跳过这一步）
[root@localhost ~]# groupadd mysql                                          #添加mysql用户组
[root@localhost ~]# useradd mysql -g mysql -s /sbin/nologin        # 添加mysql用户

以下带红色字体的命令非常非常，必须要执行
[root@localhost ~]# cd /usr/local/mysql
[root@localhost ~]# chown mysql.mysql -R .                              #将mysql目录赋予mysql用户的执行权限
[root@localhost ~]# chown mysql.mysql -R /data/mysql
[root@localhost ~]# cp support-files/my-default.cnf /etc/my.cnf  #mysql配置文件
[root@localhost ~]# chmod 755 scripts/mysql_install_db              #赋予mysql_install_db执行权限

以下命令为mysql 启动及自启动配置
[root@localhost ~]# scripts/mysql_install_db  --user=mysql  --basedir=/usr/local/mysql --datadir=/data/mysql/   

输出如下信息：

To start mysqld at boot time you have to copy

support-files/mysql.server to the right place for your system

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !

To do so, start the server, then issue the following commands:

  /usr/local/mysql/bin/mysqladmin -u root password ‘new-password‘

  /usr/local/mysql/bin/mysqladmin -u root -h ziteng26 password ‘new-password‘

Alternatively you can run:

  /usr/local/mysql/bin/mysql_secure_installation

which will also give you the option of removing the test

databases and anonymous user created by default.  This is

strongly recommended for production servers.

See the manual for more instructions.

You can start the MySQL daemon with:

  cd . ; /usr/local/mysql/bin/mysqld_safe &

You can test the MySQL daemon with mysql-test-run.pl

  cd mysql-test ; perl mysql-test-run.pl

Please report any problems with the ./bin/mysqlbug script!

The latest information about MySQL is available on the web at

  http://www.mysql.com

Support MySQL by buying support/licenses at http://shop.mysql.com

New default config file was created as /usr/local/mysql/my.cnf and

will be used by default by the server when you start it.

You may edit this file to change server settings

WARNING: Default config file /etc/my.cnf exists on the system

This file will be read by default by the MySQL server

If you do not want to use this, either remove it, or use the

--defaults-file argument to mysqld_safe when starting the server

[root@localhost ~]# cp support-files/mysql.server /etc/init.d/mysqld
[root@localhost ~]# chmod 755 /etc/init.d/mysqld
查看mysqld服务是否设置为开机启动
[root@localhost ~]# chkconfig --list|grep mysqld
设置为开机启动
[root@localhost ~]# chkconfig mysqld on

启动mysql数据库，会输出一系列有用的信息，告诉你接下去如何初始化mysql

[root@CentOS mysql]# service mysqld start

按照上述英文，我们来初始化管理员root的密码

[root@localhost ~]# /usr/local/mysql/bin/mysqladmin -u root password ‘yourpassword‘ 

此处yourpassword设置为 manager

众所周知，mysql有两种帐号类型，即localhost和%，前者限本机连接mysql，后者可用于其它机器远程连接mysql

最后，处理帐号登录问题，让root帐号密码可以本地和远程连接使用

[root@localhost ~]# /usr/local/mysql/bin/mysql -u root -p         #敲入该命令后，屏幕会提示输入密码，输入上一步设置的yourpassword

    删除root密码为空的记录

    mysql> use mysql;

    mysql> delete from user where password=‘‘;

    mysql> flush privileges;

    配置mysql允许root远程登录                                  #登录

    mysql> grant all privileges on *.* to root@‘%‘ identified by "manager";

    mysql> flush privileges;

    mysql> select User,Password,Host from user;

    上述命令如果执行成功

    mysql> quit

至此，mysql安装已经全部结束.
