關于 NRPE: Unable to read output

通過check_nrpe 來檢測check_oracle_table

/usr/local/nagios/libexec/check_nrpe -H 10.10.10.10 -c check_oracle_table

報錯  NRPE: Unable to read output

在本地直接執行/usr/local/nagios/libexec/check_oracle_table.py 輸出結果正常

根據網上博客http://blog.chinaunix.net/uid-25266990-id-3431778.html

提示 修改 /etc/sudoers

添加一行 

nagios ALL=(ALL)  NOPASSWD:/usr/local/nagios/libexec/check_oracle_table.py

注釋Defaults    requiretty

然后在遠端執行，依舊報錯 NRPE: Unable to read output

根據上面博客提示 切換nagios 用戶執行腳本

#usermod -s /bin/bash nagiosp

#su - nagios

-bash-4.1$ /usr/local/nagios/libexec/check_oracle_table.py 

File "/usr/local/nagios/libexec/check_oracle_table.py", line 5, in <module>

    import cx_Oracle,sys

ImportError: libclntsh.so.10.1: cannot open shared object file: No such file or directory

將 root 用戶的 .bash_profile 復制到 nagios 用戶

再次執行

Traceback (most recent call last):

  File "/usr/local/nagios/libexec/check_oracle_table.py", line 55, in <module>

    conn = cx_Oracle.connect('test','test',dsn)

cx_Oracle.InterfaceError: Unable to acquire Oracle environment handle

檢測發現沒有給 .bash_profile 中ORACLE_HOME=/opt/oracle/product/10.2/db_1 賦權限，

我將 整個目錄 賦權 755 

再次執行，成功！

切換到遠端

/usr/local/nagios/libexec/check_nrpe -H 10.10.10.10 -c check_oracle_table

顯示正常。
