centos下如何设置命令的别名

alias tomcat＝ "cd /usr/local/tomcat"

不过这样设置只是对于当前会话有效，重新登陆后即失效。

首先查找到登陆用户的文件夹，比如ROOT用户

1 2	cd ~ vim ~ / .bash_profile

加入

1	alias tomcat＝ "cd /usr/local/tomcat"

最后

1	source ~ / .bash_profile

这样即使是关闭了会话，以后登陆也可以直接使用别名了。

我的常用别名

1 2 3 4 5 6 7 8

alias httpd = "vi /usr/local/apache/conf/httpd.conf" alias httpdvhost = "vi /usr/local/apache/conf/extra/httpd-vhosts.conf" alias httpdmpm = "vi /usr/local/apache/conf/extra/httpd-mpm.conf" alias httpddefault = "vi /usr/local/apache/conf/extra/httpd-default.conf"   alias mycnf = "vi /etc/my.cnf"   alias vi = "vim"
