监控Redis集群服务
一、基础环境安装
https://pypi.python.org/packages/source/b/backports.ssl_match_hostname/backports.ssl_match_hostname-3.4.0.2.tar.gz
tar xvzf backports.ssl_match_hostname-3.4.0.2.tar.gz
cd backports.ssl_match_hostname-3.4.0.2
python setup.py install- 1

mv RedisLive-master RedisLive

二、 RedisLive配置
1、安装RedisLive
https:
//github.com/nkrode/RedisLive
tar -xf RedisLive-master.zip -C /data/
cd /data/
mv RedisLive-master RedisLive

其中redis-live.conf.example是作者给出的一个示例配置文件，启动服务之前把.example后缀删掉变成.conf文件，打开redis-live.conf，配置好redis实例的信息：
root@storm-master-01:/home/redis/monitor/RedisLive-master/src#ls
api dataprovider db __init__.py redis-live.conf redis-live.conf.example redis-live.py redis-monitor.py util www
root@storm-master-01:/home/redis/monitor/RedisLive-master/src#more redis-live.conf
{
"RedisServers":
[
{
"server": "192.168.1.247",
"port" : 6379
},
{
"server": "192.168.1.111",
"port" : 6379
}
],
"DataStoreType" : "sqlite",
"RedisStatsServer":
{
"server" : "192.168.1.247",
"port" : 6379
},
"SqliteStatsStore" :
{
"path": "/home/redis/monitor/RedisLive-master/src/db/redislive.sqlite"
}
}
root@storm-master-01:/home/redis/monitor/RedisLive-master/src#
在RedisServers中设置需要监控的Redis-server；
DataStoreType决定使用那种类型的数据存储，
如果是redis，使用RedisStatsServer作为数据存储的目标；
如果是sqlite，使用SqliteStatsStore作为数据存储的目标。
整个配置实际上是一个json对象，RedisServers是redis服务器的信息，由于是数组类型所以配置多个redis实例。DataStoreType是监控信息的存储方式，有”redis”和” sqlite”两种方式，分别对应下面RedisStatsServer和SqliteStatsStore，编辑完成后保存。
redis-live.py是用来启动web服务的，默认端口是8888 。redis-monitor.py就是redis监控的核心服务。
2、初始化DBcd db
cat schema.sql | sqlite3 redislive.sqlite- 1
3、配置RedisLive的定期监控
*/5 * * * * cd /data/Redis-Monitor/RedisLive/src; ./redis-monitor.py --duration 20 >/dev/null 2>&14、服务启动
RedisLive的功能分两个部分:
一个部分是redis-server状态数据的采集，通过src/redis-monitor.py来执行；
另外一部分功能是提供对状态数据的查询服务，通过src/redis-live.py来提供web服务。
./redis-monitor.py --duration 120 & //启动监控，duration是心跳时间
./redis-live.py&
//启动web服务，默认监听8888端口
注：./redis-live.py &
[root@pro-kibana src]# Traceback (most recent call last):

解决：安装sqlite
tar -xf setuptools-23.0.0.tar.gz
cd sqlite-autoconf-3130000
./configure --prefix=/usr/local/sqlite3
make && make install
netstat
-ntpl
