用Emacs訪問MySQL好久了，最近因為換了單位，重新配置環境的時候居然花了一個多小時，特此記錄。
1.Ubuntu下用sudo apt-get install 安裝
libmysqlclient-dev 和 mysql-client-core-5.5
2.下載sql.el和mysql.el，並在~/.emacs文件中加載
http://www.emacswiki.org/emacs/sql.el
http://www.emacswiki.org/emacs/mysql.el
- (load-file (expand-file-name "/opt/emacs_plugins/sql.el"))
- (load-file (expand-file-name "/opt/emacs_plugins/mysql.el"))
3.如果你的mysql端口不是標准端口的話，需要用下面的命令在.emacs文件中設置
- (setq sql-mysql-options (list "-P 6871"))
4.通過下面的命令設置兩個連接mysql的常用帳號：
- (setq sql-connection-alist
- '((pool-a
- (sql-product 'mysql)
- (sql-server "ip1")
- (sql-user "user1")
- (sql-password "pwd1")
- (sql-database "db1")
- (sql-port 6871))
- (pool-b
- (sql-product 'mysql)
- (sql-server "ip2")
- (sql-user "user2")
- (sql-password "pwd2")
- (sql-database "db2")
- (sql-port 3306))))
-
- (defun sql-connect-preset (name)
- "Connect to a predefined SQL connection listed in `sql-connection-alist'"
- (eval `(let ,(cdr (assoc name sql-connection-alist))
- (flet ((sql-get-login (&rest what)))
- (sql-product-interactive sql-product)))))
-
- (defun mysql-a ()
- (interactive)
- (sql-connect-preset 'pool-a))
-
- (defun mysql-b ()
- (interactive)
- (sql-connect-preset 'pool-b))
