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 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 optionalshell> cp support-files/my-medium.cnf /etc/my.cnf
shell> 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;
