【APP】python版本低引发pyth

发布时间:2019-09-19 08:04:45编辑:auto阅读(1581)

    系统平台:centos 6.3 x86_64

    源由:
    最近在部署nagios监控RabbitMQ,在MQ服务器运行如下命令出现如下提示:

    [root@mq01 scripts]# ./check_rabbitmq -a connection_count -W 80 -C 100
    CRITICAL - 'module' object has no attribute 'check_output'

    原因:
    Python版本太低
    [root@mq01 scripts]# python -V
    Python 2.6.6

    解决方法:升级python

    (1)安装python

    [root@mq01 zjqiu]# wget http://www.python.org/ftp/python/2.7/Python-2.7.tar.bz2
    [root@mq01 zjqiu]# tar jxf Python-2.7.tar.bz2
    [root@mq01 zjqiu]# cd Python-2.7
    [root@mq01 Python-2.7]# ./configure
    [root@mq01 Python-2.7]# make && make install

    python2.7安装后路径默认是在/usr/local/lib/python2.7
    [root@mq01 Python-2.7]# ll /usr/local/lib/
    total 9980
    -r-xr-xr-x.  1 root root 10191084 Sep  5 06:20 libpython2.7.a
    drwxr-xr-x.  2 root root     4096 Sep  5 06:22 pkgconfig
    drwxr-xr-x. 28 root root    20480 Sep  5 06:22 python2.7

    [root@mq01 Python-2.7]# /usr/local/bin/python -V
    Python 2.7

    [root@mq01 Python-2.7]# whereis python
    python: /usr/bin/python /usr/bin/python2.6 /usr/bin/python /usr/lib/python2.6 /usr/lib64/python2.6 /usr/local/bin/python2.7 /usr/local/bin/python /usr/local/bin/python2.7-config /usr/local/lib/python2.7 /usr/include/python2.6 /usr/share/man/man1/python.1.gz

    (2)建立软连接,使系统默认的python指向python2.7
    正常情况下即使python2.7安装成功后,系统默认指向的python仍然是2.6.6版本

    [root@mq01 Python-2.7]# mv /usr/bin/python /usr/bin/python.bak

    [root@mq01 Python-2.7]# ln -s /usr/local/bin/python2.7 /usr/bin/python


    (3)解决系统python软链接指向python2.7版本后,yum出错!
    方法:
    [root@mq01 Python-2.7]# vi /usr/bin/yum
    将文本编辑显示的#/usr/bin/python修改为#/usr/bin/python2.7,保存修改即可!
