centos6.5 yum 安装mysql

 

、1.需要检测系统是否安装过mysql

# yum list installed | grep mysql

2.如果发现有mysql，先删掉

# yum -y remove mysql-libs.x86_64(安装的mysql相关的东西)

3.下载mysql的yum源

# wget http://repo.mysql.com/mysql-community-release-el6-5.noarch.rpm

4.接着执行这句

# rpm -ivh mysql-community-release-el6-5.noarch.rpm

5.安装mysql

# yum install mysql-community-server

6.启动服务

# service mysqld start

8.修改密码

# mysql -u root
# use mysql;
# update user set password=PASSWORD("这里输入root用户密码") where User='root';
# flush privileges; 

9.设置开启自启动命令

chkconfig mysqld on

10.远程连接

ERROR 1130: Host 'X.X.X.X' is not allowed to connect to this MySQL server 1。

1.改表法。可能是你的帐号不允许从远程登陆，只能在localhost。这个时候只要在localhost的那台电脑，登入mysql后，更改 "mysql" 数据库里的 "user" 表里的 "host" 项，从"localhost"改称"%"

mysql -u root -p******
mysql>use mysql;
mysql>update user set host = '%' where user = 'root';

2. 授权法。例如，你想myuser使用mypassword从任何主机连接到mysql服务器的话。

mysql>GRANT ALL PRIVILEGES ON *.* to 'root'@'%' IDENTIFIED BY 'root' WITH GRANT OPTION; 

如果你想允许用户myuser从ip为X.X.X.X的主机连接到mysql服务器，并使用mypassword作为密码

mysql>GRANT ALL PRIVILEGES ON *.* TO 'root'@'192.168.1.3' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;

这句一定要加上！！！

mysql>flush privileges;
