MySQL安装、密码修改、远程登录、解决看不到mysql库问题

以前一直时在windows环境下开发，下载转到Linux环境了，各种杂七杂八的问题一堆。

今天记以下MySQL的安装、密码修改、远程登录的内容吧，好记性不如烂笔头。

http://dev.mysql.com/doc/refman/5.6/en/binary-installation.html

shell> groupadd mysql
shell> useradd -r -g mysql mysql
shell> cd /usr/local
shell> tar zxvf /path/to/mysql-VERSION-OS.tar.gz
shell> ln -s full-path-to-mysql-VERSION-OS mysql
shell> cd mysql
shell> chown -R mysql .
shell> chgrp -R mysql .
shell> scripts/mysql_install_db --user=mysql
shell> chown -R root .
shell> chown -R mysql data
# Next command is optional
shell> cp support-files/my-medium.cnf /etc/my.cnf
shell> bin/mysqld_safe --user=mysql &
# Next command is optional
shell> cp support-files/mysql.server /etc/init.d/mysql.server

修改密码常用：

mysql -u root mysql 
mysql> UPDATE user SET password=PASSWORD("new password") WHERE user='name'; 
　　mysql> FLUSH PRIVILEGES; 
　　mysql> QUIT

授权远程登录：

可以采用授权法和该表法，个人感觉授权法比较方便

授权法：

GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'%' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;

如果你想允许用户myuser从ip为192.168.1.3的主机连接到mysql服务器，并使用mypassword作为密码

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

如果你想允许用户myuser从ip为192.168.1.3的主机连接到mysql服务器的abc数据库，并使用mypassword作为密码

GRANT ALL PRIVILEGES ON abc.* TO 'myuser'@'192.168.1.3' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;

然后再執行：flush privileges;

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 -pvmwaremysql>use mysql;mysql>update user set host = '%' where user = 'root';mysql>select host, user from user;
