安装 python2.7
[root@node3 soft_bak]# tar jxvf Python-2.7.tar.bz2
[root@node3 soft_bak]# cd Python-2.7
[root@node3 Python-2.7]# ./configure --prefix=/usr/local/python2.7/
[root@node3 Python-2.7]# make
[root@node3 Python-2.7]# make install
添加/usr/local/python2.7/bin/到Linux的环境变量中
[root@node3 bin]# echo $PATH
/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin
[root@node3 bin]# PATH="$PATH":/usr/local/python2.7/bin/
[root@node3 bin]# echo $PATH
/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin:/usr/local/python2.7/bin/
删除/usr/bin中的python文件，为python2.7创建连接
[root@node3 bin]# cd /usr/bin/
[root@node3 bin]# rm -rf python
[root@node3 bin]# ln -s /usr/local/python2.7/bin/python ./python
[root@node3 bin]# python

解决Python升级后yum不能用的问题
#修改yum文件
vi /usr/bin/yum
将文件头部的
#！/usr/bin/python
改为如下内容
#！/usr/bin/python2.6
安装psutil
[root@node3 soft_bak]# tar zxvf psutil-3.2.2.tar.gz
[root@node3 PGMonitor]# cd psutil-3.2.2
[root@node3 psutil-3.2.2]# python setup.py install
安装psycopg2
[root@node3 soft_bak]# tar zxvf psycopg2-2.6.1.tar.gz
[root@node3 PGMonitor]# cd psycopg2-2.6.1
[root@node3 psycopg2-2.6.1]# python setup.py build_ext --pg-config /usr/local/pg945/bin/pg_config build
[root@node3 psycopg2-2.6.1]# python setup.py build_ext --pg-config /usr/local/pg945/bin/pg_config install
