今天在执行python脚本时报如下错误:
[root@localhost ~]# python mysql_watcher.py -p dbset.ini
Traceback (most recent call last):
  File "mysql_watcher.py", line 17, in
    import psutil
ImportError: No module named psutil
经查询,psutil是python的系统性能信息模块，正确的安装方法如下:
[root@localhost ~]# yum install python-setuptools
Loaded plugins: fastestmirror, refresh-packagekit, security
Loading mirror speeds from cached hostfile
