1)下载:

在mysql的网站上,下载  mysql-5.6.13-linux-glibc2.5-x86_64.tar.gz 

比如拷贝到 /soft/mysql5/ 目录下。

2)解压:

[root@server local]#cd /usr/local
[root@server local]#tar zxvf /soft/mysql5/mysql-5.6.13-linux-glibc2.5-x86_64.tar.gz

3)建立软链接:

[root@server local]#ln -s mysql-5.6.13-linux-glibc2.5-x86_64 mysql

  查看:  

       [root@server local]# ls -lrt mysql
       lrwxrwxrwx 1 root root 36 9月 12 13:22 mysql -> ./mysql-5.6.13-linux-glibc2.5-x86_64
       [root@server local]#

4)建立mysql相关的用户和组:

[root@server local]#groupadd mysql
[root@server local]#useradd -r -g mysql mysql

 

5)生成数据库:

[root@server local]# cd mysql
[root@server local]# chown -R mysql .
[root@server local]#chgrp -R mysql .
[root@server local]# scripts/mysql_install_db --user=mysql
[root@server local]# chown -R root .
[root@server local]# chown -R mysql data

 

6)拷贝必要的文件(此为可选步骤):

[root@server local]#cp support-files/mysql.server /etc/init.d/mysql.server

 

7)启动数据库:

[root@server local]bin/mysqld_safe --user=mysql &

 

8)访问数据库:

[root@server ~]# mysql --user=mysql
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 2

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

mysql> show databases;
+--------------------+
| Database |
+--------------------+
| information_schema |
| test |
+--------------------+
2 rows in set (0.00 sec)

mysql> quit
Bye
[root@server ~]#

 

9)关闭数据库时,发现无法关闭数据库,于是强制关闭进程,然后退出。

10)设置权限:

重新启动数据库(带 --skip-grant-tables参数):

[root@server ~]# mysqld_safe --skip-grant-tables &
[1] 3140
[root@server ~]# 130912 14:49:51 mysqld_safe Logging to '/usr/local/mysql/data/server.gao.err'.
130912 14:49:51 mysqld_safe Starting mysqld daemon with databases from /usr/local/mysql/data

设置root用户的口令(被要求Enter password的时候,直接按回车键就过去了):

[root@server ~]# mysql -uroot -p
Enter password:

mysql> use mysql;

Database changed
mysql> update user set password=password("abcdef") where user='root' and host='localhost';

Rows matched: 1 Changed: 1 Warnings: 0

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

mysql> quit
Bye
[root@server ~]#

为了验证是否可以正常关闭,再次重新启动来看一下:

[root@server ~]# mysqld_safe --skip-grant-tables
130912 14:57:36 mysqld_safe Logging to '/usr/local/mysql/data/server.gao.err'.
130912 14:57:36 mysqld_safe Starting mysqld daemon with databases from /usr/local/mysql/data

[root@server ~]#

然后运行:

[root@server ~]# mysqladmin -uroot shutdown
[root@server ~]#

 成功关闭。

下一次,完全正常启动,看能否关闭:

[root@server ~]# mysqld_safe
130912 15:01:26 mysqld_safe Logging to '/usr/local/mysql/data/server.gao.err'.
130912 15:01:26 mysqld_safe Starting mysqld daemon with databases from /usr/local/mysql/data

 

[root@server ~]# mysqladmin -uroot -p shutdown
Enter password:
[root@server ~]#

关闭成功了。
