一个 mysql server 上的小技巧
在my.cnf 的 mysql 端 添加如下设置
[mysql] #no-auto-rehash # faster start of mysql but no tab completition prompt="(\u:mysql1@linuxbyte.org \R:\m)[\d]: "
会产生如下效果:
root@ubuntu:/home/hew# mysql -u hew -p Enter password: Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 320 Server version: 5.1.41-3ubuntu12.1 (Ubuntu) Type 'help;' or '\h' for help. Type '\c' to clear the current input statement. (hew:mysql1@linuxbyte.org 21:12)[(none)]: use linuxbyte #注意这里 Database changed (hew:mysql1@linuxbyte.org 21:13)[linuxbyte]: use linuxsky; #这里 Reading table information for completion of table and column names You can turn off this feature to get a quicker startup with -A Database changed (hew:mysql1@linuxbyte.org 21:13)[linuxsky]: #这里
如上所示我们可以在mysql命令行下显示当前的mysql 用户，所在主机，时间和所用的数据库。
这个在关键时刻可以让我们避免很多误操作。
