PostgreSQL Monitor pg_view
https://github.com/zalando/pg_view
Requirements
Linux 2.6, python 2.6, psycopg2, curses
查看系统是否有curses
[root@node3 /]# ls /usr/include/ncurses*
/usr/include/ncurses_dll.h /usr/include/ncurses.h
系统已经安装了curses，如果没有下载安装curses
下载安装 curses
curses 的GNU实现 ncurses，官网下载地址：http://ftp.gnu.org/gnu/ncurses/
下载 ncurses 的最新版本；
[root@node3 soft_bak]tar zxvf ncurses-6.0.tar.gz
[root@node3 soft_bak] cd ncurses-6.0
[root@node3 soft_bak] ./configure
[root@node3 soft_bak] make
[root@node3 soft_bak] make install
默认的安装，头文件在 /usr/include 下，库在 /usr/lib 下。
也可以使用yum安装
搜索 ： yum search ncurses
安装 ： yum install ncurses
软件包
Python-2.7.tar.bz2 psycopg2-2.6.1.tar.gz psutil-3.2.2.tar.gz
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
安装setuptools
[root@node3 soft_bak]# tar zxvf setuptools-19.2.tar.gz
[root@node3 setuptools-19.2]# cd setuptools-19.2
[root@node3 setuptools-19.2]# python setup.py install
[root@node3 soft_bak]# unzip pg_view-master.zip
[root@node3 soft_bak]# cd pg_view-master
将opt/soft_bak/pg_view-master目录下setup.py 中的
第112行 long_description=read('README.md'),改为如下
long_description=read('README.rst'),
[root@node3 pg_view-master]# python setup.py install
[root@node3 soft_bak]# cd /usr/local/python2.7/bin/
[root@node3 bin]# ls
2to3 easy_install easy_install-2.7 idle pg_view pydoc python python2.7 python2.7-config python-config smtpd.py
启动PostgreSQL
[postgres@node3 bin]$ ./pg_ctl -D ../data/ start
server starting
postgres 用户执行 pg_view
[postgres@node3 ~]$ cd /usr/local/python2.7/bin/
[postgres@node3 bin]$ ./pg_view
生成少量数据
[postgres@node3 bin]$ ./pgbench -i -F 100 -s 142 -h localhost -p 5432 -U postgres postgres
进程pgbench测试
[postgres@node3 bin]$ ./pgbench -h localhost -p 5432 -d postgres -U postgres -c 50 -j 10 -T 600
