[root@localhost mysql]#

PS: mysql5.7新特性：由上面可以看出， mysql_install_db 已经不再推荐使用了，建议改成 mysqld --initialize 完成实例初始化。

加入MySQL为系统服务:

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

[root@localhost mysql]# chkconfig mysqld on

[root@localhost mysql]# chkconfig --list|grep mysqld

mysqld          0:off  1:off  2:on    3:on    4:on    5:on    6:off

[root@localhost mysql]#chmod 755 /etc/init.d/mysqld

MySQL服务启动、重启、停止

[root@localhost mysql]# serivce mysqld start

[root@localhost mysql]# serivce mysqld stop

[root@localhost mysql]# serivce mysqld restart

[root@localhost mysql]#

设置环境变量:

[root@localhost mysql]# vim /etc/profile

export PATH=/usr/local/mysql/bin:$PATH

[root@localhost mysql]#

检查MySQL是否能开启

[root@localhost mysql]# cd /usr/local/mysql

[root@localhost mysql]# cd support-files/

[root@localhost support-files]# ./mysql.server start

Starting MySQL.. SUCCESS!

若改用了， 则在启动服务时会出现如下错误：

# ./support-files/mysql.server start

./support-files/mysql.server: line 276: cd: /usr/local/mysql: No such file or directory

Starting MySQL ERROR! Couldn't find MySQL server (/usr/local/mysql/bin/mysqld_safe)

这时候我们需要修改/support-files/mysql.server文件的basedir和datadir目录路径为我们正确的mysql的basedir和datadir路径， 如下：

# vim support-files/mysql.server

--------------------------

...

basedir=/usr/local/mysql

datadir=/data/mysql/data

...

--------------------------

# ./support-files/mysql.server start

Starting MySQL.. SUCCESS!

创建配置文件

将默认生成的my.cnf备份

# mv /etc/my.cnf /etc/my.cnf.bak

[root@localhost support-files]# cp my-default.cnf  /etc/my.cnf

初始化mysql用户root的密码

先将mysql服务停止

# service mysqld stop

进入mysql安装目录， 执行：

# cd /usr/local/mysql

# ./bin/mysqld_safe --skip-grant-tables --skip-networking&

[1] 6225

[root@localhost mysql]# 151110 02:46:08 mysqld_safe Logging to '/data/mysql/data/localhost.localdomain.err'.

151110 02:46:08 mysqld_safe Starting mysqld daemon with databases from /data/mysql/data

另外打开一个终端(p.s. 如果是ssh连接登录的, 另外创建一个ssh连接即可)， 执行操作如下：

# mysql -u root mysql

到此， 设置完mysql用户root的密码且确保mysql编码集是utf8, 注意上面， 新版本的mysql.user表里的密码字段是authentication_string

MySQL远程授权

格式如下：

mysql> grant all [privileges] on db_name.table_name to 'username'@'host' identified by 'password';

示例如下：

mysql> grant all privileges on *.* to 'root'@'%' identified by '123456';

Query OK, 0 rows affected, 1 warning (0.04 sec)

mysql> FLUSH PRIVILEGES;

Query OK, 0 rows affected (0.00 sec)

mysql>

或用

mysql> grant all on *.* to 'root'@'%' identified by '123456';

到此， 完成了mysql的安装 及配置！！！
