添加系统全局变量：
步骤1：使用root用户登录，在家目录下修改.bash_profile文件，查看结果如下：
[root@server132 ~]# more .bash_profile
# .bash_profile# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
# User specific environment and startup programs
PATH=$PATH:$HOME/bin
export PATH
unset USERNAME
alias p='ps -ef|grep java'
alias rm='rm -i'
alias so='su - oracle'
alias sppd='/opt/jinrong/spider/bin/shutdown.sh'
alias sptm='/opt/jinrong/tomcat/bin/shutdown.sh'
alias stpd='/opt/xizang/spider/bin/startup.sh'
alias sttm='/opt/xizang/tomcat/bin/startup.sh'
alias tpd='tail -f /opt/jinrong/spider/logs/catalina.out'
alias ttm='tail -f /opt/xizang/tomcat/logs/catalina.out'
步骤2：
source ~/.bash_profile
关闭当前终端，重新打开终端，执行缩写命令即可
