經過codis完成redis管理

一：phpredisadmin工具：相似於mysqladmin管理mysql同樣php

安裝環境：html

[root@node5 ~]# yum install httpd php php-redis -y

下載管理包：前端

[root@node5 html]# git clone https://github.com/erikdubbelboer/phpRedisAdmin.git

更更名稱並解決依賴：java

[root@node5 html]# mv phpRedisAdmin admin
[root@node5 html]# cd admin
[root@node5 admin]# git clone https://github.com/nrk/predis.git vendor #解決依賴包

啓動http,啓動前確認80端口沒有被佔用，若是被佔用能夠修改監聽的默認端口爲80覺得的其餘端口：node

[root@node5 html]# /etc/init.d/httpd  restart
Stopping httpd:                                            [FAILED]
Starting httpd:                                            [  OK  ]
[root@node5 html]# chkconfig  httpd on

訪問http://ServerIP/admin：python

報錯，沒法打開，查看apache錯誤日誌以下：mysql

[Mon Mar 21 21:24:47 2016] [error] [client 192.168.10.1] PHP Fatal error:  require(): Failed opening required '/var/www/html/admin/includes/../vendor/autoload.php' (include_path='.:/usr/share/pear:/usr/share/php') in /var/www/html/admin/includes/common.inc.php on line 2

解決過程：linux

[root@node5 admin]# cd includes/
[root@node5 includes]# ls config.sample.inc.php  config.inc.php 
[root@node5 includes]# vim config.inc.php 
$config = array(
  'servers' => array(
    array(
      'name'   => 'local server', // Optional name.
      'host'   => '192.168.10.205', #配置爲本身的主機IP
      'port'   => 6379,
      'filter' => '*',

      // Optional Redis authentication.
      //'auth' => 'redispasswordhere' // Warning: The password is sent in plain-text to the Redis server.
    ),  

保存退出後從新啓動httpd：

[root@node5 includes]# /etc/init.d/httpd restart
Stopping httpd: [ OK ]
Starting httpd: [ OK ]git

再次測試仍是不能訪問，報錯以下：github

[Mon Mar 21 21:55:27 2016] [error] [client 192.168.10.1] PHP Fatal error:  Call to undefined function mb_internal_encoding() in /var/www/html/admin/includes/common.inc.php on line 59

解決辦法：

[root@node5 admin]# vim /var/www/html/admin/includes/common.inc.php
mb_internal_encoding('utf-8'); 
將此行改成註釋，以下：
#mb_internal_encoding('utf-8');

訪問：

配置管理多個reids Server：

[root@node5 includes]# pwd
/var/www/html/admin/includes
[root@node5 includes]# vim config.inc.php

$config = array(
  'servers' => array(
    array(
      'name'   => '182.168.10.205', // Optional name.
      'host'   => '192.168.10.205',
      'port'   => 6379,
      'filter' => '*',

      // Optional Redis authentication.
      //'auth' => 'redispasswordhere' // Warning: The password is sent in plain-text to the Redis server.
    ),  

    array(  #一個主機一個配置，名稱自定義，IP和端口是Redis的IP和端口
      'name'   => '7001', // Optional name.name支持中文
      'host'   => '192.168.10.205',
      'port'   => 7001, 
    ),  

    array(
      'name'   => '7002', // Optional name.
      'host'   => '192.168.10.205',
      'port'   => 7002, 
    ),  

    array(
      'name'   => '7003', // Optional name.
      'host'   => '192.168.10.205',
      'port'   => 7003, 
    ),

更改完成之後無需重啓apache，若是瀏覽器已經打開管理地址，刷新一下便可：

二：rdbtools管理工具：

使用pip命令安裝,若是沒有pip命令則先安裝pip：

[root@node5 ~]# yum install python-pip

使用pip安裝rdbtools： pip install rdbtools

[root@node5 ~]# pip install rdbtools
/usr/lib/python2.6/site-packages/pip/_vendor/requests/packages/urllib3/util/ssl_.py:90: InsecurePlatformWarning: A true SSLContext object is not available. This prevents urllib3 from configuring SSL appropriately and may cause certain SSL connections to fail. For more information, see https://urllib3.readthedocs.org/en/latest/security.html#insecureplatformwarning.
  InsecurePlatformWarning
You are using pip version 7.1.0, however version 8.1.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
Collecting rdbtools

導出rdb中的key信息：

[root@node5 7001]# rdb -c memory dump_7001.rdb  >  memory.csv #而後將memory.csv文件下載到本地，便可用excel打開分析了，格式以下圖：

三：經過saltstack管理redis：

模塊名稱：redismod

官方文檔地址：https://docs.saltstack.com/en/latest/ref/modules/all/index.html

四：經過codis完成redis管理：

1.codis簡介：

　　Codis 是一個分佈式 Redis 解決方案, 對於上層的應用來講, 鏈接到 Codis Proxy 和鏈接原生的 Redis Server 沒有明顯的區別 (不支持的命令列表), 上層應用能夠像使用單機的 Redis 同樣使用, Codis 底層會處理請求的轉發, 不停機的數據遷移等工做, 全部後邊的一切事情, 對於前面的客戶端來講是透明的, 能夠簡單的認爲後邊鏈接的是一個內存無限大的 Redis 服務.其架構以下：

Codis 由四部分組成:

Codis Proxy (codis-proxy) #負責對redis server 的代理，能夠在前端使用haproxy作負載均衡，負責調度redis-client的請求。
Codis Dashboard (codis-config) #codis的管理工具，能夠添加刪除redis節點，發起數據遷移，還自帶一個http server，提供一個dashboard能夠在瀏覽器進行觀察和配置。
Codis Redis (codis-server) #基於redis 2.8作了一個分支，只能運行codis-server
ZooKeeper/Etcd #Codis 依賴 ZooKeeper 來存放數據路由表和 codis-proxy 節點的元信息, codis-config 發起的命令都會經過 ZooKeeper 同步到各個存活的 codis-proxy.

codis-proxy 是客戶端鏈接的 Redis 代理服務, codis-proxy 自己實現了 Redis 協議, 表現得和一個原生的 Redis 沒什麼區別 (就像 Twemproxy), 對於一個業務來講, 能夠部署多個 codis-proxy, codis-proxy 自己是無狀態的.

codis-config 是 Codis 的管理工具, 支持包括, 添加/刪除 Redis 節點, 添加/刪除 Proxy 節點, 發起數據遷移等操做. codis-config 自己還自帶了一個 http server, 會啓動一個 dashboard, 用戶能夠直接在瀏覽器上觀察 Codis 集羣的運行狀態.

2.準備基礎環境：

安裝go語言並設置環境變量：

[root@node5 opt]# yum install golang -y #codis是基於go語言編寫的，所以要安裝go語言環境
[root@node5 opt]# mkdir /opt/gopath #保存go環境的路徑
[root@node5 opt]# vim /etc/profile
    export GOPATH=/opt/gopath
[root@node5 opt]# source  /etc/profile

安裝配置zookeeper，須要有java環境:

[root@node5 ~]# wget http://mirrors.cnnic.cn/apache/zookeeper/zookeeper-3.4.6/zookeeper-3.4.6.tar.gz
[root@node5 ~]# mv zookeeper-3.4.6 /usr/local/zookeeper  #移動到目錄
[root@node5 ~]# cd /usr/local/zookeeper/conf/   #進入到目錄
[root@node5 conf]# cp zoo_sample.cfg  /opt/zoo.cfg  #複製配置文件
[root@node5 conf]# cd /opt/
[root@node5 opt]# mkdir zk1 zk2 zk3 #準備zookeeper 服務ID，每一個服務器的ID是不一樣的
[root@node5 opt]# echo 1 > zk1/myid
[root@node5 opt]# echo 2 > zk2/myid
[root@node5 opt]# echo 3 > zk3/myid
[root@node5 opt]# vim zoo.cfg #編輯配置文件
　　dataDir=/opt/zk1 #保存數據的命令
　　clientPort=2181 #客戶端鏈接的端口
　　server.1 = 192.168.10.205:2887:3887 
　　server.2 = 192.168.10.205:2888:3888
　　server.3 = 192.168.10.205:2889:3889

[root@node5 opt]# cp zoo.cfg zk1/zk1.cfg
[root@node5 opt]# cp zoo.cfg zk2/zk2.cfg
[root@node5 opt]# cp zoo.cfg zk3/zk3.cfg

[root@node5 opt]# vim zk2/zk2.cfg #每一個服務對應不一樣的目錄
　　dataDir=/opt/zk2
　　clientPort=2182
[root@node5 opt]# vim zk3/zk3.cfg
　　dataDir=/opt/zk3
　　clientPort=2183

詳細配置:

[root@node5 opt]# grep '^[a-z]' zk3/zk3.cfg 
tickTime=2000 #服務器和客戶端的心跳維持間隔，間隔多久發送心跳
initLimit=10 #選舉的時候的時間間隔是10次，10次 * 2000微秒
syncLimit=5 # Leader 與 Follower 之間發送消息，請求和應答時間長度，最長不能超過多少個 tickTime 的時間長度
dataDir=/opt/zk3 #數據保存目錄
clientPort=2181 #客戶端鏈接的端口
server.1 = 192.168.10.205:2887:3887 #集羣端口和ID配置
server.2 = 192.168.10.205:2888:3888
server.3 = 192.168.10.205:2889:3889

詳細解釋：
tickTime：這個時間是做爲 Zookeeper 服務器之間或客戶端與服務器之間維持心跳的時間間隔，也就是每一個 tickTime 時間就會發送一個心跳。
dataDir：顧名思義就是 Zookeeper 保存數據的目錄，默認狀況下，Zookeeper 將寫數據的日誌文件也保存在這個目錄裏。
clientPort：這個端口就是客戶端鏈接 Zookeeper 服務器的端口，Zookeeper 會監聽這個端口，接受客戶端的訪問請求。
initLimit：這個配置項是用來配置 Zookeeper 接受客戶端（這裏所說的客戶端不是用戶鏈接 Zookeeper 服務器的客戶端，而是 Zookeeper 服務器集羣中鏈接到 Leader 的 Follower 服務器）初始化鏈接時最長能忍受多少個心跳時間間隔數。當已經超過 5個心跳的時間（也就是 tickTime）長度後 Zookeeper 服務器尚未收到客戶端的返回信息，那麼代表這個客戶端鏈接失敗。總的時間長度就是 5*2000=10 秒
syncLimit：這個配置項標識 Leader 與 Follower 之間發送消息，請求和應答時間長度，最長不能超過多少個 tickTime 的時間長度，總的時間長度就是 2*2000=4 秒
server.A=B：C：D：其中 A 是一個數字，表示這個是第幾號服務器；B 是這個服務器的 ip 地址；C 表示的是這個服務器與集羣中的 Leader 服務器交換信息的端口；D 表示的是萬一集羣中的 Leader 服務器掛了，須要一個端口來從新進行選舉，選出一個新的 Leader，而這個端口就是用來執行選舉時服務器相互通訊的端口。若是是僞集羣的配置方式，因爲 B 都是同樣，因此不一樣的 Zookeeper 實例通訊端口號不能同樣，因此要給它們分配不一樣的端口號。

啓動每一個zookeeper 服務：

[root@node5 opt]# /usr/local/zookeeper/bin/zkServer.sh  start  /opt/zk1/zk1.cfg 
JMX enabled by default
Using config: /opt/zk1/zk1.cfg
Starting zookeeper ... STARTED
[root@node5 opt]# /usr/local/zookeeper/bin/zkServer.sh  start  /opt/zk2/zk2.cfg 
JMX enabled by default
Using config: /opt/zk2/zk2.cfg
Starting zookeeper ... STARTED
[root@node5 opt]# /usr/local/zookeeper/bin/zkServer.sh  start  /opt/zk3/zk3.cfg 
JMX enabled by default
Using config: /opt/zk3/zk3.cfg
Starting zookeeper ... STARTED

確認端口啓動成功：

[root@node5 opt]# ss -tnl | grep 2181
LISTEN     0      50                       :::2181                    :::*     
[root@node5 opt]# ss -tnl | grep 2182
LISTEN     0      50                       :::2182                    :::*     
[root@node5 opt]# ss -tnl | grep 2183
LISTEN     0      50                       :::2183                    :::*     
[root@node5 opt]#

查看每一個節點的狀態：

[root@node5 opt]# /usr/local/zookeeper/bin/zkServer.sh  status /opt/zk1/zk1.cfg 
JMX enabled by default
Using config: /opt/zk1/zk1.cfg
Mode: follower
[root@node5 opt]# /usr/local/zookeeper/bin/zkServer.sh  status /opt/zk2/zk2.cfg 
JMX enabled by default
Using config: /opt/zk2/zk2.cfg
Mode: leader  #這是主的，另外兩個是從的，表示已經啓動完成
[root@node5 opt]# /usr/local/zookeeper/bin/zkServer.sh  status /opt/zk3/zk3.cfg 
JMX enabled by default
Using config: /opt/zk3/zk3.cfg
Mode: follower

鏈接到zookeeper節點：

[root@node5 opt]# /usr/local/zookeeper/bin/zkCli.sh  -server  192.168.10.205:2181

[root@node5 opt]# /usr/local/zookeeper/bin/zkCli.sh  -server  192.168.10.205:2181Connecting to 192.168.10.205:2181

make gotest 測試過程

執行所有指令後，會在 bin 文件夾內生成 codis-config、codis-proxy、codis-server三個可執行文件。另外, bin/assets 文件夾是 codis-config 的 dashboard http 服務須要的前端資源, 須要和 codis-config 放置在同一文件夾下)

[root@node5 codis]# cd bin/
[root@node5 bin]# ls
assets  codis-config  codis-proxy  codis-server

可執行文件使用方式：

[root@node5 bin]# ./codis-config  -h

[root@node5 bin]# ./codis-config  -h 
usage: codis-config  [-c <config_file>] [-L <log_file>] [--log-level=<loglevel>]
        <command> [<args>...]
options:
   -c   #配置文件地址
   -L   #日誌輸出文件地址
   --log-level=<loglevel>   #輸出日誌級別 (debug < info (default) < warn < error < fatal)

commands:
    server            #redis 服務器組管理
    slot              #slot 管理
    dashboard         #啓動 dashboard 服務
    action            #事件管理 (目前只有刪除歷史事件的日誌)
    proxy             #proxy 管理

[root@node5 bin]# ./codis-proxy -h

$ bin/codis-proxy -h
usage: codis-proxy [-c <config_file>] [-L <log_file>] [--log-level=<loglevel>] [--cpu=<cpu_num>] [--addr=<proxy_listen_addr>] [--http-addr=<debug_http_server_addr>]

options:
   -c    #配置文件地址
   -L    #日誌輸出文件地址
   --log-level=<loglevel>   #輸出日誌級別 (debug < info (default) < warn < error < fatal)
   --cpu=<cpu_num>      #proxy佔用的 cpu 核數, 默認1, 最好設置爲機器的物理cpu數的一半到2/3左右
   --addr=<proxy_listen_addr>       #proxy 的 redis server 監聽的地址, 格式 <ip or hostname>:<port>, 如: localhost:9000, :9001
   --http-addr=<debug_http_server_addr>    #proxy 的調試信息啓動的http server, 能夠訪問 http://debug_http_server_addr/debug/vars

[root@node5 bin]# ./codis-server  -h

[root@node5 bin]# ./codis-server  -h
Usage: ./redis-server [/path/to/redis.conf] [options]
       ./redis-server - (read config from stdin)  #指定redis配置文件
       ./redis-server -v or --version  #顯示版本
       ./redis-server -h or --help #獲取幫助
       ./redis-server --test-memory <megabytes> #單位爲字節

Examples:
       ./redis-server (run the server with default conf)
       ./redis-server /etc/redis/6379.conf
       ./redis-server --port 7777
       ./redis-server --port 7777 --slaveof 127.0.0.1 8888
       ./redis-server /etc/myredis.conf --loglevel verbose

開始部署：

[root@node5 bin]# cd ..
[root@node5 codis]# vim config.ini

zk=192.168.10.205:2181
dashboard_addr=192.168.10.205:18087

配置並啓動 dashboard：

[root@node5 codis]# cp config.ini bin/ #將修改後的文件複製至bin目錄，由於bin裏面你的命令默認讀取當前目錄的config.ini文件，或可使用 -c指定也能夠

[root@node5 bin]# ./codis-config dashboard & #該命令會啓動 dashboard

啓動成功就能夠經過 http://ServerIP:18087訪問

初始化 slots：

執行./codis-config slot init，該命令會在zookeeper上建立slot相關信息，若是提示已經初始化能夠加 -f 強制

[root@node5 bin]# ./codis-config slot init -f
{
  "msg": "OK",
  "ret": 0
}

啓動 Codis Redis：

若是已經啓動能夠跳過，若是還未啓動就執行：

[root@node5 bin]# /etc/init.d/redisd  start

添加 Redis Server Group：

每個 Server Group 做爲一個 Redis 服務器組存在, 只容許有一個 master, 能夠有多個 slave, group id 僅支持大於等於1的整數

添加一個master：

[root@node5 bin]# ./codis-config server add 1 localhost:6379 master
{
  "msg": "OK",
  "ret": 0
}

爲master添加一個slave：

[root@node5 bin]# ./codis-config server add 1 192.168.10.205:7009 slave

在瀏覽器驗證：

設置 server group 服務的 slot 範圍：

Codis 採用 Pre-sharding 的技術來實現數據的分片, 默認分紅 1024 個 slots (0-1023), 對於每一個key來講, 經過如下公式肯定所屬的 Slot Id : SlotId = crc32(key) % 1024 每個 slot 都會有一個且必須有一個特定的 server group id 來表示這個 slot 的數據由哪一個 server group 來提供：

如:

設置編號爲[0, 511]的 slot 由 server group 1 提供服務, 編號 [512, 1023] 的 slot 由 server group 2 提供服務

[root@node5 bin]# ./codis-config slot range-set 0 511 1 online
{
  "msg": "OK",
  "ret": 0
}
[root@node5 bin]# ./codis-config slot range-set 512 1023 2 online
{
  "msg": "OK",
  "ret": 0
}

啓動 codis-proxy：

[root@node5 bin]# ./codis-proxy -c config.ini -L ./log/proxy.log  --cpu=8 --addr=0.0.0.0:19000 --http-addr=0.0.0.0:11000

  _____  ____    ____/ /  (_)  _____
 / ___/ / __ \  / __  /  / /  / ___/
/ /__  / /_/ / / /_/ /  / /  (__  )
\___/  \____/  \__,_/  /_/  /____/

剛啓動的 codis-proxy 默認是處於 offline狀態的, 而後設置 proxy 爲 online 狀態, 只有處於 online 狀態的 proxy 纔會對外提供服務

[root@node5 bin]# ./codis-config -c config.ini proxy online proxy_1
{
  "msg": "OK",
  "ret": 0
}

注：命令格式爲./codis-config -c config.ini proxy online <proxy_name> <---- proxy的id, 如 proxy_1，能夠在瀏覽器看到
