MySQL配置

1. 创建mysql运行使用的mysql :

   /usr/sbin/groupadd mysql

   /usr/sbin/useradd -g mysql mysql

2. 创建binlog和库的存储路径并赋予mqsql用户权限

   mkdir -p /usr/local/webserver/mysql/binlog/www/data_mysql
   chown mysql.mysql /usr/local/webserver/mysql/binlog/ /www/data_mysql

3. 创建my.cn配置文件

   将/etc/my.cn替换为:

   $ cat /etc/my.cnf

4. 初始化数据库

   /usrlocal/webserver/mysql/scripts/mysql_install_db --defaults-file=/etc/my.cnf --user=mysql

5. 创建开机启动的脚本

   cd /usr/local/webserver/mysql
   cp support-fiels/mysql.server /ect/rc.d/init.d/mysqld
   chkconfig --add mysqld
   chkconfig --level 35 mysqld on

6. 启动mysql服务器

   serveice mysqld start

7. 连接MySQL

   /usr/local/erbserver/mysql/bin/mysql -u root -p

修改MYSQL用户密码

mysqladmin -u用户名 -p旧密码 password新密码
或
SET PASSWORD FOR '用户名@主机'=PASSWORD('密码')
​
创建并授权
grant all privileges on *.* to 用户名@'%' identified by '密码'  with grant option;

其他命令

1. service mysqld start 启动

2. service mysqld stop 停止

3. service mysqld restart 重启

4. service mysql reload 重新配置
