[[email protected] mysql]# ./bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql/data

[[email protected] 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:
[[email protected] mysql]# cp support-files/mysql.server  /etc/init.d/mysqld
[[email protected] mysql]# chkconfig mysqld on
[[email protected] mysql]# chkconfig --list|grep mysqld
mysqld          0:off  1:off  2:on    3:on    4:on    5:on    6:off
[[email protected] mysql]#chmod 755 /etc/init.d/mysqld
 
MySQL服务启动、重启、停止
[[email protected] mysql]# serivce mysqld start
[[email protected] mysql]# serivce mysqld stop
[[email protected] mysql]# serivce mysqld restart
[[email protected] mysql]#
设置环境变量:
[[email protected] mysql]# vim /etc/profile
export PATH=/usr/local/mysql/bin:$PATH
[[email protected] mysql]#
检查MySQL是否能开启

[[email protected] mysql]# cd /usr/local/mysql
[[email protected] mysql]# cd support-files/
[[email protected] 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
[[email protected] 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
[[email protected] 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!!!
