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
shell>/path/to/mysql-VERSION-OS
.tar.gzln -s
shell>full-path-to-mysql-VERSION-OS
mysqlcd 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;
