unzip RedisLive-master.zip
mv RedisLive-master RedisLive
http://distfiles.macports.org/py-setuptools/
setuptools-36.2.7.zip sh setuptools*
二、RedisLive配置
1、安裝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是作者給出的一個示例配置檔案，啟動服務之前把.example字尾刪掉變成.conf檔案，開啟redis-live.conf，配置好redis例項的資訊：

api dataprovider db __init__.py redis-live.conf redis-live.conf.example redis-live.py redis-monitor.py util www

{
"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"
}
}
[email protected]:/home/redis/monitor/RedisLive-master/src#
在RedisServers中設定需要監控的Redis-server；
DataStoreType決定使用那種型別的資料儲存，
如果是redis，使用RedisStatsServer作為資料儲存的目標；
如果是sqlite，使用SqliteStatsStore作為資料儲存的目標。
整個配置實際上是一個json物件，RedisServers是redis伺服器的資訊，由於是陣列型別所以配置多個redis例項。DataStoreType是監控資訊的儲存方式，有”redis”和” sqlite”兩種方式，分別對應下面RedisStatsServer和SqliteStatsStore，編輯完成後儲存。
redis-live.py是用來啟動web服務的，預設埠是8888 。redis-monitor.py就是redis監控的核心服務。
2、初始化DBcd db
cat schema.sql | sqlite3 redislive.sqlite- 1
3、配置RedisLive的定期監控
*/5 * * * * cd /data/Redis-Monitor/RedisLive/src; ./redis-monitor.py --duration 20 >/dev/null 2>&14、服務啟動
RedisLive的功能分兩個部分:
一個部分是redis-server狀態資料的採集，通過src/redis-monitor.py來執行；
另外一部分功能是提供對狀態資料的查詢服務，通過src/redis-live.py來提供web服務。
./redis-monitor.py --duration 120 & //啟動監控，duration是心跳時間
./redis-live.py&
//啟動web服務，預設監聽8888埠
注：./redis-live.py &

解決：安裝sqlite
tar -xf setuptools-23.0.0.tar.gz
cd sqlite-autoconf-3130000
./configure --prefix=/usr/local/sqlite3
make && make install
netstat -ntpl |grep python
[email protected]:/home/redis/monitor/RedisLive-master/src#netstat -anltp|grep pythontcp 0 0 0.0.0.0:8888 0.0.0.0:* LISTEN 194074/python tcp 0 0 192.168.1.247:43929 192.168.1.247:3309

yum erase ruby ruby-libs ruby-mode ruby-rdoc ruby-irb ruby-ri ruby-docs1）安裝ruby 2.0以上 tar -xf ruby-2.1.9.tar.gz cd ruby-2.1.9./configure --prefix=/usr/local/ruby2.0makemake install配置連線： cd /usr/local/ruby2.0/for i in `ls`;do ln -s /usr/local/ruby2.0/bin/$i
/usr/bin/$i;done新增淘寶源： gem sources --add https://ruby.taobao.org/ --remove https://rubygems.org/2）安裝redis-stat cd /data/git clone https://github.com/junegunn/redis-stat.gitcd /data/redis-stat/bin/# ./redis-stat --help
命令列執行：
redis-stat
redis-stat 1
redis-stat 1 10
redis-stat --verbose
redis-stat localhost:6380 1 10
redis-stat localhost localhost:6380 localhost:6381 5
redis-stat localhost localhost:6380 1 10 --csv=/tmp/output.csv --verbose
|
redis-stat執行為服務：
redis-stat --server
redis-stat --verbose --server=8080 5
# redis-stat server can be daemonized
redis-stat --server --daemon
# Kill the daemon
killall -9 redis-stat-daemon
|
以守護程序模式啟動：
redis-stat --verbose --server=8080 5 --daemon
|
執行其它主機例項：
./redis-stat 192.168.1.12 --auth='1234' --verbose --server=8080 5 --daemon
