2.下载RedisLive
[root@sht-sgmhadoopdn-04 app]# wget https://github.com/nkrode/RedisLive/archive/master.zip
[root@sht-sgmhadoopdn-04 app]# unzip master
[root@sht-sgmhadoopdn-04 app]# mv RedisLive-master RedisLive
[root@sht-sgmhadoopdn-04 app]# cd RedisLive/
[root@sht-sgmhadoopdn-04 RedisLive]# ll
total 20
drwxr-xr-x 2 root root 4096 Aug 20  2015 design
-rw-r--r-- 1 root root 1067 Aug 20  2015 MIT-LICENSE.txt
-rw-r--r-- 1 root root  902 Aug 20  2015 README.md
-rw-r--r-- 1 root root   58 Aug 20  2015 requirements.txt
drwxr-xr-x 7 root root 4096 Aug 20  2015 src
[root@sht-sgmhadoopdn-04 RedisLive]#

3.查看版本要求(刚开始安装没注意版本，直接pip导致后面各种问题，所以请仔细看下面过程)
[root@sht-sgmhadoopdn-04 RedisLive]# cat requirements.txt
argparse==1.2.1
python-dateutil==1.5
redis
tornado==2.1.1

[root@sht-sgmhadoopdn-04 RedisLive]# cd ../

4.pip安装环境要求
[root@sht-sgmhadoopdn-04 app]# pip install tornado
[root@sht-sgmhadoopdn-04 app]# pip install redis
[root@sht-sgmhadoopdn-04 app]# pip install python-dateutil
[root@sht-sgmhadoopdn-04 app]# pip install argparse

5.进入 /root/learnproject/app/RedisLive/src目录,配置redis-live.conf文件

[root@sht-sgmhadoopdn-04 app]# cd -
/root/learnproject/app/RedisLive
[root@sht-sgmhadoopdn-04 RedisLive]# cd src
[root@sht-sgmhadoopdn-04 src]# ll
total 40

[root@sht-sgmhadoopdn-04 src]#
[root@sht-sgmhadoopdn-04 src]# cp redis-live.conf.example redis-live.conf
[root@sht-sgmhadoopdn-04 src]#
[root@sht-sgmhadoopdn-04 src]# vi redis-live.conf
{
        "RedisServers":
        [
                {
                        "server": "172.16.101.66",

        ],

        "DataStoreType" : "redis",

        "RedisStatsServer":
        {
          "server" : "172.16.101.66",

6.第一次尝试启动redis-monitor.py抛错 _sqlite3

[root@sht-sgmhadoopdn-04 src]# ./redis-monitor.py --duration 120
ImportError: No module named _sqlite3

[root@sht-sgmhadoopdn-04 src]# yum install -y sqlite-devel
[root@sht-sgmhadoopdn-04 src]# yum install -y sqlite

[root@sht-sgmhadoopdn-04 ~]# find / -name _sqlite3.so

[root@sht-sgmhadoopdn-04 ~]# cp /usr/local/python27/lib/python2.7/lib-dynload/_sqlite3.so /usr/local/lib/python2.7/lib-dynload/
[root@sht-sgmhadoopdn-04 ~]# python

7.第二次尝试启动redis-monitor.py抛错 redis

[root@sht-sgmhadoopdn-04 src]# ./redis-monitor.py --duration 120
ImportError: No module named redis

[root@sht-sgmhadoopdn-04 src]# find / -name redis
/etc/rc.d/init.d/redis

/usr/local/redis
/usr/local/python27/lib/python2.7/site-packages/redis
[root@sht-sgmhadoopdn-04 src]#
[root@sht-sgmhadoopdn-04 src]# cp -r  /usr/local/python27/lib/python2.7/site-packages/redis  /usr/local/lib/python2.7/lib-dynload/
[root@sht-sgmhadoopdn-04 src]# python

8.第三次尝试启动redis-monitor.py，成功；按ctrl+c中断掉

[root@sht-sgmhadoopdn-04 src]# ./redis-monitor.py --duration 120

[root@sht-sgmhadoopdn-04 src]#

9.尝试第一次启动redis-live.py ，tornado.ioloop

[root@sht-sgmhadoopdn-04 src]# ./redis-live.py
Traceback (most recent call last):
  File "./redis-live.py", line 3, in
    import tornado.ioloop
ImportError: No module named tornado.ioloop
[root@sht-sgmhadoopdn-04 src]# find / -name  tornado
/usr/local/python27/lib/python2.7/site-packages/tornado
[root@sht-sgmhadoopdn-04 src]# cp -r /usr/local/python27/lib/python2.7/site-packages/tornado  /usr/local/lib/python2.7/lib-dynload/

10.尝试第二次启动redis-live.py ，singledispatch
[root@sht-sgmhadoopdn-04 src]# ./redis-live.py
Traceback (most recent call last):
  File "./redis-live.py", line 6, in
    import tornado.web
  File "/usr/local/lib/python2.7/lib-dynload/tornado/web.py", line 84, in
    from tornado import gen
  File "/usr/local/lib/python2.7/lib-dynload/tornado/gen.py", line 98, in
    from singledispatch import singledispatch  # backport
ImportError: No module named singledispatch

###这个 singledispatch 错误，其实就是在tornado里的，谷歌和思考过后，怀疑是版本问题，于是果断卸载tornado
[root@sht-sgmhadoopdn-04 src]# pip uninstall tornado
[root@sht-sgmhadoopdn-04 src]# rm -rf  /usr/local/lib/python2.7/lib-dynload/tornado
[root@sht-sgmhadoopdn-04 src]# find / -name tornado
[root@sht-sgmhadoopdn-04 src]#
##假如find有的话 ，就要手工删除掉

11.于是想想其他也是要卸载掉
[root@sht-sgmhadoopdn-04 src]# pip uninstall argparse
[root@sht-sgmhadoopdn-04 src]# pip uninstall python-dateutil
[root@sht-sgmhadoopdn-04 src]# find / -name argparse
[root@sht-sgmhadoopdn-04 src]# find / -name python-dateutil
##假如find有的话 ，就要手工删除掉

12.关键一步: 根据step3的指定版本来安装

[root@sht-sgmhadoopdn-04 src]# pip install -v tornado==2.1.1
[root@sht-sgmhadoopdn-04 src]# pip install -v argparse==1.2.1
[root@sht-sgmhadoopdn-04 src]# pip install -v python-dateutil==1.5

13.再次尝试启动redis-live.py ，抛错dateutil.parser

[root@sht-sgmhadoopdn-04 src]# ./redis-live.py
Traceback (most recent call last):
  File "./redis-live.py", line 10, in
    from api.controller.ServerListController import ServerListController
  File "/root/learnproject/app/RedisLive/src/api/controller/ServerListController.py", line 1, in
    from BaseController import BaseController
  File "/root/learnproject/app/RedisLive/src/api/controller/BaseController.py", line 4, in
    import dateutil.parser
ImportError: No module named dateutil.parser
[root@sht-sgmhadoopdn-04 src]#
[root@sht-sgmhadoopdn-04 src]#
[root@sht-sgmhadoopdn-04 src]#
[root@sht-sgmhadoopdn-04 src]#
[root@sht-sgmhadoopdn-04 src]# find / -name dateutil
/usr/local/python27/lib/python2.7/site-packages/dateutil
[root@sht-sgmhadoopdn-04 src]# cp -r /usr/local/python27/lib/python2.7/site-packages/dateutil  /usr/local/lib/python2.7/lib-dynload/
You have mail in /var/spool/mail/root

14.再在尝试启动redis-live.py ，成功了，然后按ctrl+c中断掉

[root@sht-sgmhadoopdn-04 src]# ./redis-live.py
^CTraceback (most recent call last):
  File "./redis-live.py", line 36, in
    tornado.ioloop.IOLoop.instance().start()
  File "/usr/local/lib/python2.7/lib-dynload/tornado/ioloop.py", line 283, in start
    event_pairs = self._impl.poll(poll_timeout)
KeyboardInterrupt
[root@sht-sgmhadoopdn-04 src]#

 
 15.启动

[root@sht-sgmhadoopdn-04 src]# ./redis-monitor.py --duration 120 &
[root@sht-sgmhadoopdn-04 src]# ./redis-live.py  &
