yum安装MySQL并设置密码

Shell代码

yum install mysql

yum install mysql-server

yum install mysql-devel

chgrp -R mysql /var/lib/mysql

chmod -R 770 /var/lib/mysql

service mysqld start

mysql

SET PASSWORD FOR 'root'@'localhost' = PASSWORD('secret_password');

设置默认编码等一些初始参数（my.cnf）(若无my.cnf, 则可cp /usr/share/mysql/my-small.cnf /etc/my.cnf)

vi /etc/my.cnf

[mysqld]

datadir=/var/lib/mysql

socket=/var/lib/mysql/mysql.sock

user=mysql

default-character-set=utf8 [添加]

default-storage-engine=INNODB [添加]

old_passwords=1

[client]

default-character-set=utf8 [添加]

[mysqld_safe]

log-error=/var/log/mysqld.log

pid-file=/var/run/mysqld/mysqld.pid

下面就是常规的操作了：

更改 root 密码: mysqladmin -u root password 'newpassword'

添加mysql用户： GRANT ALL PRIVILEGES ON my_db.* TO 'user'@'localhost' IDENTIFIED BY'password';

删除test数据库: mysql -u root -p mysql> DROP DATABASE test;

删除匿名帐户: DELETE FROM mysql.user WHERE user = '';

重载权限: mysql> FLUSH PRIVILEGES;

如要其他机器能访问，在mysql.user中添加一个Host为'%'的user,然后flush priviledges;，最后防火墙加一句类似这样的语句即可(开通3306端口)：

Shell代码

-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 3306 -j ACCEPT

如果要reboot自启动：

Shell代码

chkconfig --levels 345 mysqld on
