codis集群安装

在网上找了很多codis的集群安装方法，看起来都是大同小异，本人结合了大多种方法完成了一套自己使用的codis的集群安装，可以供大家学习使用，如果有什么问题或者不懂的地方欢迎指正

1.集群规划:
三台机器：192.168.0.207     192.168.0.213       192.168.0.214 确保每台都有zookper 注意，下面有一部分crxy93 96 97 分别对应207 213 214

codis-dashboard 192.168.0.207 改服务器服务器需要部署的东西
codis-fe 192.168.0.207
codis-ha 192.168.0.207 192.168.0.207

codis-proxy1      codis-proxy2     codis-proxy3 如果codis-proxy1 codis_group1_M(6379)挂了 会自动切换到下面节点上后面的也是
codis_group1_M(6379)  codis_group2_M(6379)   codis_group3_M(6379)
codis_group3_S(6380) codis_group1_S(6380)   codis_group2_S(6380)

下面的图是整个集群的工作流程

2.目录规划：                                                                           mkdir -p 创建目录
日志目录:      /codisapp/logs/codis
配置文件目录： /codisapp/conf/codis
pid文件目录:  /codisapp/run/codis
相关启动脚本目录: /codisapp/sh/codis
codis-server数据目录: /codisapp/dbdat/redis_data_6379   /codisapp/dbdat/redis_data_6380

3 集群基础环境安装:(具体视本地环境调整) 注意！下面步骤三台需要同时安装!

(1)安装jdk1.7

tar -zxvf jdk-7u71-linux-x64.tar.gz

将java环境变量添加至/etc/profile下

export JAVA_HOME=/usr/local/jdk

export PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin

配置完成输入source /etc/profile 命令使其生效、之后在输入java -version 查看jdk是否生效

(2)安装zookeeper(保证奇数个节点,其他视具体情况)

(2.1)上传zookeeper至/usr/local/ 下并解压: tar -zxvf zookeeper-3.4.6.tar.gz

(2.2)重命名 mv zookeeper-3.4.6 zookeeper

(2.3)把conf/zoo_sample.cfg重命名为conf/zoo.cfg

(2.4) vi zoo.cfg

a、修改 dataDir=/usr/local/zookeeper/data

b、添加：

server.1=cdh205:2888:3888

server.2=cdh213:2888:3888

server.3=cdh214:2888:3888

c、创建data文件夹：  mkdir zookeeper/data

d、echo 1 >data/myid

(2.5) 把zookeeper复制到cdh213  cdh214上去

scp -rq zookeeper/ cdh213:/usr/local/

scp -rq zookeeper/ cdh214:/usr/local/

(2.6) 修改myid:

cdh213 : echo 2 >zookeeper/data/myid

cdh214 : echo 3 >zookeeper/data/myid

(3)编译codis：                                             下载到/usr/local目录下

3.1）codis版本：3.0.3 版本   https://github.com/CodisLabs/codis/archive/3.0.3.zip

(3.2) go使用版本：go1.5.2.linux-amd64.tar.gz      https://golang.org/doc/install?download=go1.5.2.linux-amd64.tar.gz

(3.3) 安装编译环境前的一些依赖安装(三台主机上执行）

yum install -y gcc make gcc-c++ automake lrzsz openssl-devel zlib-* bzip2-* readline* zlib-* bzip2-* git

yum install -y nmap unzip wget lsof xz net-tools mercurial

(3.4)修改：

vi /etc/sysctl.conf

vm.overcommit_memory = 1

sysctl vm.overcommit_memory=1

手工执行：echo never > /sys/kernel/mm/transparent_hugepage/enabled

并加到:/etc/rc.local中

(4)安装go环境:

tar -zxvf /usr/local/go1.5.2.linux-amd64.tar.gz

创建工作路径：

mkdir /root/gopkg

修改 /etc/profile文件

vi /etc/profile

#profile文件修改如下,注意这里是添加环境变量，视具体情况而定

export GOROOT=/usr/local/go

export GOPATH=/root/gopkg

export PATH=$GOROOT/bin:$PATH

使环境变量生效： source /etc/profile

查看go版本：

[root@mvxl2579 tmp]# go version

go version go1.5.2 linux/amd64

(5)配置dns解析：

vi /etc/resolv.conf

nameserver 10.16.0.100

nameserver 10.16.15.110

nameserver 114.114.114.114

(6)goderp安装：

(6.1)创建指定目录

mkdir -p $GOPATH/src/github.com/tools

cd $GOPATH/src/github.com/tools

(6.2)

go get -u github.com/tools/godep

[root@mvxl2579 tools]# cd godep

[root@mvxl2579 godep]# go install ./  ---该命令会将 godep 生成到 $GOPATH/bin 下

将$GOPATH/bin加到/etc/profile中：

vi /etc/profile

export PATH=$GOROOT/bin:$GOPATH/bin:$PATH

source /etc/profile

[root@mvxl2579 godep]# which godep

/root/gopkg/bin/godep

[root@mvxl2579 godep]# godep version

godep v72 (linux/amd64/go1.5.2)

(7)解压codis包

unzip /usr/local/codis-3.0.3.zip

创建目录

mkdir -p /root/gopkg/src/github.com/CodisLabs

将解压的包复制在指定目录

cp -r /usr/local/codis-3.0.3 /root/gopkg/src/github.com/CodisLabs/codis

进入到改目录下

cd /root/gopkg/src/github.com/CodisLabs/codis

(7.1)执行make（这里一定要注意，回去google上下载一些包，使用FQ软件，下载 ,如果没报错就不需要FQ。）

执行全部指令后，会在 bin 文件夹内生成

codis-admin

codis-dashboard

codis-fe

codis-ha

codis-proxy

codis-server

六个可执行文件.另外, bin/assets 文件夹是 codis-dashboard  http 服务需要的前端资源, 需要和codis-dashboard 放置在同一文件夹下。

[root@mvxl2579 codis]# cd bin

[root@mvxl2579 bin]# ls -ltr

total 71156

-rwxr-xr-x 1 root root  6311067 May 31 09:02 codis-server

-rw-r--r-- 1 root root       96 May 31 09:02 version

-rwxr-xr-x 1 root root 18415720 May 31 09:10 codis-dashboard

-rwxr-xr-x 1 root root 11056192 May 31 09:10 codis-proxy

-rwxr-xr-x 1 root root 17600776 May 31 09:10 codis-admin

-rwxr-xr-x 1 root root  9957704 May 31 09:10 codis-ha

-rwxr-xr-x 1 root root  9498560 May 31 09:10 codis-fe

drwxr-xr-x 4 root root     4096 May 31 09:10 assets

(7.1)下面的mkdir 需三台机器都执行

mkdir /codisapp/svr/codis

mkdir -p /codisapp/conf/codis

mkdir -p /codisapp/logs/codis

mkdir -p /codisapp/sh/codis

mkdir -p /codisapp/run/codis/

mkdir -p /codisapp/dbdat/redis_data_6379

mkdir -p /codisapp/dbdat/redis_data_6380

cp -r /root/gopkg/src/github.com/CodisLabs/codis/bin  /codisapp/svr/codis/

由于codis 本身只有codis-server,没有redis-cli,需要把redis 2.8.21 安装包里面的几个程序 redis-benchmark redis-check-aof redis-check-dump redis-cli

copy到/codisapp/svr/codis/bin

(7.2)进入到redis目录下将四个文件拷贝到bin目录三个机器都要执行

[root@mvxl2579 redis-2.8.21]# cd /root/gopkg/src/github.com/CodisLabs/codis/extern/redis-2.8.21

[root@mvxl2579 redis-2.8.21]# cp redis-benchmark    /codisapp/svr/codis/bin

[root@mvxl2579 redis-2.8.21]# cp redis-check-aof    /codisapp/svr/codis/bin

[root@mvxl2579 redis-2.8.21]# cp redis-check-dump   /codisapp/svr/codis/bin

[root@mvxl2579 redis-2.8.21]# cp redis-cli          /codisapp/svr/codis/bin

[root@mvxl2579 redis-2.8.21]# cd /root/gopkg/src/github.com/CodisLabs/codis/extern/redis-2.8.21/src

(7.3)codis copy 到其他机器：

[root@mvxl2579 redis-2.8.21]# scp -r /codisapp/svr/codis/bin 192.168.0.213:/codisapp/svr/codis/

[root@mvxl2579 redis-2.8.21]# scp -r /codisapp/svr/codis/bin 192.168.0.214:/codisapp/svr/codis/

3.配置各个组件：

(1)配置 Codis 的Redis

配置文件 : /codisapp/conf/codis/redis6379.conf    里面设置密码: xxxxx  ---这里也可以不设置密码

(2)考虑性能，主库关闭aof和rdp，从库只开启aof:

cd /root/gopkg/src/github.com/CodisLabs/codis/extern/redis-2.8.21/

cp redis.conf /codisapp/conf/codis/redis6379.conf

cp redis.conf /codisapp/conf/codis/redis6380.conf

(3)将redis6379.conf更改以下参数(主库)：

[root@mvxl2579 redis-2.8.21]# vi /codisapp/conf/codis/redis6379.conf  (这里使用查找的方式逐个修改各个参数，不要复制粘贴，密码可以不用设置)

(4)做完之后将修改好的东西拷贝到其他两台电脑

[root@mvxl2579 redis-2.8.21]# cd /codisapp/conf/codis

[root@mvxl2579 redis-2.8.21]# scp -p * 192.168.0.96:/codisapp/conf/codis

[root@mvxl2579 redis-2.8.21]# scp -p * 192.168.0.97:/codisapp/conf/codis

(5)生成dashboard配置文件          下面的配置文件ip根据自己的IP进行设置

[root@mvxl2579 redis-2.8.21]# /codisapp/svr/codis/bin/codis-dashboard --default-config | tee /codisapp/conf/codis/dashboard.toml

[root@mvxl2579 redis-2.8.21]# vi /codisapp/conf/codis/dashboard.toml

#                                                #

#                  Codis-Dashboard               #

#                                                #

##################################################

# Set Coordinator, only accept "zookeeper" & "etcd"

coordinator_name = "zookeeper"

#这里的zookeeper设置根据实际情况写，不要照抄

coordinator_addr = "192.168.0.93:2181,192.168.0.94:2181,192.168.0.95:2181,192.168.0.96:2181,192.168.0.97:2181"

# Set Codis Product {Name/Auth}.

product_name = "hls_prod"

product_auth = ""

# Set bind address for admin(rpc), tcp only.

admin_addr = "192.168.0.93:18080"

(6) 生成codis-proxy配置文件

[root@mvxl2579 redis-2.8.21]# /codisapp/svr/codis/bin/codis-proxy --default-config | tee /codisapp/conf/codis/proxy.toml

[root@mvxl2579 redis-2.8.21]# vi /codisapp/conf/codis/proxy.toml

##################################################

#                                                #

#                                                #

##################################################

# Set Codis Product {Name/Auth}.

product_name = "hls_prod"

product_auth = ""

# Set bind address for admin(rpc), tcp only.

admin_addr = "0.0.0.0:11080"

# Set bind address for proxy, proto_type can be "tcp", "tcp4", "tcp6", "unix" or "unixpacket".

proto_type = "tcp4"

proxy_addr = "0.0.0.0:19000"

# Set jodis address & session timeout.

#这里的zookeeper设置根据实际情况写，不要照抄

jodis_addr = "192.168.0.93:2181,192.168.0.94:2181,192.168.0.95:2181,192.168.0.96:2181,192.168.0.97:2181"

jodis_timeout = 10

# Proxy will ping-pong backend redis periodly to keep-alive

backend_ping_period = 5

# If there is no request from client for a long time, the connection will be droped. Set 0 to disable.

session_max_timeout = 1800

# Buffer size for each client connection.

session_max_bufsize = 131072

# Number of buffered requests for each client connection.

# Make sure this is higher than the max number of requests for each pipeline request, or your client may be blocked.

session_max_pipeline = 1024

# Set period between keep alives. Set 0 to disable.

session_keepalive_period = 60

(7)生成codis-fe配置文件

生成配置文件:

配置文件 codis.json 可以手动编辑，也可以通过 codis-admin 从外部存储中拉取:

/codisapp/svr/codis/bin/codis-admin --dashboard-list --zookeeper=127.0.0.1:2181 | tee /codisapp/conf/codis/codis.json

(8)编写dashboard启动和停止脚本：

vi /codisapp/sh/codis/start_codis_dashboard.sh

#!/bin/sh

CODIS_HOME=/codisapp/svr/codis

nohup $CODIS_HOME/bin/codis-dashboard --ncpu=4 --config= is/dashboard.toml --log=/codisapp/logs/codis/dashboard.log --log-level=WARN &

vi /codisapp/sh/codis/stop_codis_dashboard.sh

/codisapp/svr/codis/bin/codis-admin --dashboard=192.168.0.93:18080 --shutdown

(9)编写codis_proxy启停脚本

vi /codisapp/sh/codis/start_codis_proxy.sh

#!/bin/sh

CODIS_HOME=/codisapp/svr/codis

# start codis-proxy

nohup $CODIS_HOME/bin/codis-proxy --ncpu=4 --config=/codisapp/conf/codis/proxy.toml --log=/codisapp/logs/codis/proxy.log --log-level=WARN &

sleep 3s

# set codis-proxy online

$CODIS_HOME/bin/codis-admin --dashboard=192.168.0.93:18080 --create-proxy -x 192.168.0.93:11080

vi /codisapp/sh/codis/stop_codis_proxy.sh

/codisapp/svr/codis/bin/codis-admin --proxy=192.168.0.93:11080 --auth="xxxxx" --shutdown

(10)编写codis_fe启停脚本

vi /codisapp/sh/codis/start_codis_fe.sh

#!/bin/sh

CODIS_HOME=/codisapp/svr/codis

nohup $CODIS_HOME/bin/codis-fe --ncpu=4 --log=/codisapp/logs/codis/fe.log --log-level=WARN --dashboard-list=/codisapp/conf/codis/codis.json --listen=192.168.0.93:8080 &

vi /codisapp/sh/codis/stop_codis_fe.sh

ps -ef|grep codis-fe|grep -v grep|awk '{print $2}'|xargs kill

(11)编写coids_ha启停脚本

vi /codisapp/sh/codis/start_codis_ha.sh

#!/bin/sh

CODIS_HOME=/codisapp/svr/codis

nohup $CODIS_HOME/bin/codis-ha --log=/codisapp/logs/codis/ha.log --log-level=WARN --dashboard=192.168.0.93:18080 &

vi /codisapp/sh/codis/stop_codis_ha.sh

ps -ef|grep codis-ha|grep -v grep|awk '{print $2}'|xargs kill

(12) 拷贝配置文件到其他两台机器上

scp /codisapp/conf/codis/dashboard.toml 192.168.0.213:/codisapp/conf/codis/dashboard.toml

scp /codisapp/conf/codis/dashboard.toml 192.168.0.214:/codisapp/conf/codis/dashboard.toml

scp /codisapp/conf/codis/proxy.toml 192.168.0.213:/codisapp/conf/codis/proxy.toml

scp /codisapp/conf/codis/proxy.toml 192.168.0.214:/codisapp/conf/codis/proxy.toml

scp /codisapp/conf/codis/codis.json 192.168.0.213:/codisapp/conf/codis/codis.json

scp /codisapp/conf/codis/codis.json 192.168.0. 214:/codisapp/conf/codis/codis.json

(13)将启动脚本拷贝到其他两台主机上。

scp -rq /codisapp/sh/codis crxy96:/codisapp/sh/codis

scp -rq /codisapp/sh/codis crxy96:/codisapp/sh/codis

并修改其中对应的 dashboard 地址 和 addr地址

比如说： crxy96上的

vi /codisapp/sh/codis/start_codis_proxy.sh

#!/bin/sh

CODIS_HOME=/codisapp/svr/codis

# start codis-proxy

nohup $CODIS_HOME/bin/codis-proxy --ncpu=4 --config=/codisapp/conf/codis/proxy.toml --log=/codisapp/logs/codis/proxy.log --log-level=WARN &

sleep 3s

# set codis-proxy online

#注意这里的--dashboard=192.168.0.93:18080 只能有一个 --create-proxy -x 192.168.0.93:11080 这里的地址要改成crxy96的地址，即192.168.0.96:11080

$CODIS_HOME/bin/codis-admin --dashboard=192.168.0.93:18080 --create-proxy -x 192.168.0.93:11080

依次类推，修改完成所有的脚本

4.启动各个组件

(1)启动redis实例 (3台机器都要启动)

/codisapp/svr/codis/bin/codis-server  /codisapp/conf/codis/redis6379.conf &

/codisapp/svr/codis/bin/codis-server  /codisapp/conf/codis/redis6380.conf &

(2)启动dashboard (只启动crxy93的一台)

sh /codisapp/sh/codis/start_codis_dashboard.sh

(3)启动codis-proxy (3台机器都要启动)

sh /codisapp/sh/codis/start_codis_proxy.sh

(4)启动codis-fe (只启动crxy93的一台)

sh /codisapp/sh/codis/start_codis_fe.sh

(5)启动codis-ha (启动crxy93和crxy96两台)

sh /codisapp/sh/codis/start_codis_ha.sh

(6)打开浏览器 输入http://192.168.0.93:8080/ 看是否出现codis主页

(7)查看codis-proxy个数(只启动192.168.0.207的一台))

/codisapp/svr/codis/bin/codis-admin --dashboard=192.168.0.93:18080 --proxy-status
[ ] proxy-1 [T] cdf5409122a19af4bb9870d713210a06 [A] 192.168.0.93:11080 [P] 192.168.0.93:19000
[ ] proxy-2 [T] cf039a1b796ac2f4f90069a909ca23e5 [A] 192.168.0.96:11080 [P] 192.168.0.96:19000
[ ] proxy-3 [T] 0d6d305a5885d4e093a97d69612220f7 [A] 192.168.0.97:11080 [P] 192.168.0.97:19000

5.配置codis实例
(1)添加组(service-group)
/codisapp/svr/codis/bin/codis-admin --dashboard=192.168.0.207:18080 --create-group --gid=1
/codisapp/svr/codis/bin/codis-admin --dashboard=192.168.0.207:18080 --create-group --gid=2
/codisapp/svr/codis/bin/codis-admin --dashboard=192.168.0.207:18080 --create-group --gid=3

(2)向组中添加coids-proxy实例
/codisapp/svr/codis/bin/codis-admin --dashboard=192.168.0.207:18080 --group-add --gid=1 --addr=192.168.0.207:6379
/codisapp/svr/codis/bin/codis-admin --dashboard=192.168.0.207:18080 --group-add --gid=1 --addr=192.168.0.214:6380
/codisapp/svr/codis/bin/codis-admin --dashboard=192.168.0.207:18080 --group-add --gid=2 --addr=192.168.0.213:6379

6.验证安装是否成功
(1)进入zookeeper查看proxy在线状态,应为在线（"state": "online",）：
[zk: localhost:2181(CONNECTED) 11] get /codis3/hls_prod/proxy
{
"addr": "192.168.0.97:19000",
"start_at": "2016-09-25 05:05:38.456353266 -0700 PDT",
"state": "online",
"token": "0d6d305a5885d4e093a97d69612220f7"
}
cZxid = 0x3b0000007f
ctime = Sun Sep 25 05:05:27 PDT 2016
mZxid = 0x3b0000007f
mtime = Sun Sep 25 05:05:27 PDT 2016
pZxid = 0x3b0000007f
cversion = 0
dataVersion = 0
aclVersion = 0
ephemeralOwner = 0x45760f36a420010
dataLength = 167
numChildren = 0

[zk: localhost:2181(CONNECTED) 12] get /codis3/hls_prod/proxy
{
"addr": "192.168.0.93:19000",
"start_at": "2016-09-25 05:04:55.527947055 -0700 PDT",
"state": "online",
"token": "cdf5409122a19af4bb9870d713210a06"
}
cZxid = 0x3b00000077
ctime = Sun Sep 25 05:04:58 PDT 2016
mZxid = 0x3b00000077
mtime = Sun Sep 25 05:04:58 PDT 2016
pZxid = 0x3b00000077
cversion = 0
dataVersion = 0
aclVersion = 0
ephemeralOwner = 0x45760f36a42000e
dataLength = 167
numChildren = 0

[zk: localhost:2181(CONNECTED) 13] get /codis3/hls_prod/proxy
{
"addr": "192.168.0.96:19000",

}
cZxid = 0x3b0000007b
ctime = Sun Sep 25 05:05:11 PDT 2016
mZxid = 0x3b0000007b
mtime = Sun Sep 25 05:05:11 PDT 2016
pZxid = 0x3b0000007b
cversion = 0
dataVersion = 0
aclVersion = 0
ephemeralOwner = 0x45760f36a42000f
dataLength = 167
numChildren = 0

(2)在crxy93上启动redis-cli 6379，设置一个键值对，观察其在 crxy97 6380端口上是否能取到,如下操作
crxy93:
[root@crxy93 bin]# /codisapp/svr/codis/bin/redis-cli -c -p 6379
127.0.0.1:6379> set cuijiahao 1
OK
127.0.0.1:6379> get cuijiahao
"1"

crxy97:
[root@crxy97 bin]# /codisapp/svr/codis/bin/redis-cli -c -p 6380
127.0.0.1:6380> get cuijiahao
"1"

如果显示证明codis集群安装成功~可以使用~
