环境:Centos 6.5
Linux 使用yum命令安装mysql
1. 先检查系统是否装有mysql
[root@localhost ~]#yum list installed mysql*
[root@localhost ~]#rpm –qa|grep mysql*
2. 查看有没有安装包
[root@localhost ~]#yum list mysql*
3. 安装mysql客户端
[root@localhost ~]yum install mysql
4. 安装mysql服务端
[root@localhost ~]#yum install mysql-server
[root@localhost ~]#yum install mysql-devel
5. 在/etc/my.cnf 文件中加入默认字符集
[root@localhost ~]#vim /etc/my.cnf
6. 启动或者关闭mysql服务
[root@localhost ~]#service mysqld start --启动mysql 或者 /etc/init.d/mysqld start (关闭mysql #service mysql stop)
6. 设置开机启动mysql服务
[root@localhost ~]# chkconfig --add mysqld
7. 创建root用户 密码为123456
mysqladmin –u root password 123456
[root@localhost ~]# mysqladmin -u root password 123456
8. 连接mysql
[root@localhost ~]# mysql -u root -p --输入密码123456
9. 设置远程访问权限
mysql> use mysql
mysql> GRANT ALL PRIVILEGES ON *.* TO ‘admin’@’%’IDENTIFIED BY ‘admin’ WITH GRANT OPTION;
--第一个admin为用户名,第二个admin为密码,%表示所有的电脑都可以链接
mysql> flush privileges; --设置立即生效
mysql> SELECT DISTINCT CONCAT('User:''',user,'''@''',host,''';') AS query FROM mysql.user;
mysql> exit; --退出mysql服务
[root@localhost ~]# vi /etc/my.cnf
[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
user=mysql
default-character-set=utf8
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
#设备地址
bind-address=0.0.0.0 #设置设备地址
[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
[root@localhost ~]# service mysqld start --重启mysql服务
[root@localhost ~]# mysql -u root -p --连接mysql输入密码
mysql> show global variables like ‘port’; --查看端口号
