MySQL安裝、密碼修改、遠程登入、解決看不到mysql庫問題

以前一直時在windows環境下開發,下載轉到Linux環境了,各種雜七雜八的問題一堆。

今天記以下MySQL的安裝、密碼修改、遠程登入的內容吧,好記性不如爛筆頭。

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

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

修改密碼常用:

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

授權遠程登入:

可以採用授權法和該表法,個人感覺授權法比較方便

授權法:

GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'%' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;如果你想允許使用者myuser從ip為192.168.1.3的主機串連到mysql伺服器,並使用mypassword作為密碼GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'192.168.1.3' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;如果你想允許使用者myuser從ip為192.168.1.3的主機串連到mysql伺服器的abc資料庫,並使用mypassword作為密碼GRANT ALL PRIVILEGES ON abc.* TO 'myuser'@'192.168.1.3' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;然後再執行:flush privileges;

改表法:

可能是你的帳號不允許從遠程登陸,只能在localhost。這個時候只要在localhost的那台電腦,登入mysql後,更改 "mysql" 資料庫裡的 "user" 表裡的 "host" 項,從"localhost"改稱"%"mysql -u root -pvmwaremysql>use mysql;mysql>update user set host = '%' where user = 'root';mysql>select host, user from user;
