Redis集群部署(手动安装)

1. 安装依赖包

注意：本节需要使用root用户操作

1.1 安装ruby

yum install ruby -y
yum install ruby-devel.x86_64 -y

1.2 安装rubygem

有些系统默认没有rubygems的包，可能需要手动安装，先安装好ruby-irb和ruby-rdoc，然后操作以下步骤。

(1) 下载rubygem包，https://rubygems.org/?locale=zh-CN

(2) 上传rubygems-2.4.8.zip至/redis目录

(3) 解压，安装

unzip rubygems-2.4.8.zip
cd rubygems-2.4.8
ruby setup.rb

1.3 安装redis-gem

上传redis.gem至/redis目录,执行命令gem install -l redis-3.2.2.gem

2. 安装Redis集群

本节开始可使用root用户或者你规划的用户安装redis

2.1 redis安装

上传redis-3.2.1.tar.gz到/redis目录

tar -zxvf redis-3.2.1.tar.gz
cd redis-3.2.1
make
make install PREFIX=/redis/redis

执行make命令可能会遇到这两种错误:

(1)

make[3]: gcc：命令未找到
make[3]: *** [net.o] 错误 127
make[3]: Leaving directory `/home/wxyuan/redis-3.2.1/deps/hiredis‘
make[2]: *** [hiredis] 错误 2
make[2]: Leaving directory `/home/wxyuan/redis-3.2.1/deps‘
make[1]: [persist-settings] 错误 2 (忽略)
    CC adlist.o
/bin/sh: cc: command not found
make[1]: *** [adlist.o] 错误 127
make[1]: Leaving directory `/home/wxyuan/redis-3.2.1/src‘
make: *** [all] 错误 2

错误原因：缺少gcc包

解决方法：执行命令yum install gcc -y安装gcc包

(2)

cd src && make all
make[1]: Entering directory `/home/wxyuan/redis-3.2.1/src‘
    CC adlist.o
在包含自 adlist.c：34 的文件中:
zmalloc.h:50:31: 错误：jemalloc/jemalloc.h：没有那个文件或目录
zmalloc.h:55:2: 错误：#error "Newer version of jemalloc required"
make[1]: *** [adlist.o] 错误 1
make[1]: Leaving directory `/home/wxyuan/redis-3.2.1/src‘
make: *** [all] 错误 2

原因分析和解决方法，请参考https://blog.csdn.net/bugall/article/details/45914867

2.2 创建节点目录

mkdir -p /redis/redis/cluster/7380
mkdir -p /redis/redis/cluster/7381

2.3 修改配置文件

将/redis/redis-3.2.1下的配置文件redis.conf拷贝到/redis/redis/cluster/7380下，并作如下修改

bind 192.168.1.101 127.0.0.1 #注意192.168.1.10改成你的机器IP。绑定多个IP，既可以远程访问，也可以本地客户端访问
port 7380 #端口可以修改
appendonly yes
daemonize yes
cluster-enabled yes
cluster-config-file /redis/redis/cluster/7380/nodes.conf
cluster-node-timeout 5000

2.4 复制配置文件redis.conf到其他节点

cp /redis/redis/cluster/7380/redis.conf /redis/redis/cluster/7381/redis.conf
# port、cluster-config-file需要修改下
#--------------------------------------------------------
#port 7381
#cluster-config-file /redis/redis/cluster/7381/nodes.conf
#------------------------------------------------------

2.5 启动redis

执行如下命令启动redis

[wxyuan@node1 ~]$ /redis/redis/bin/redis-server /redis/redis/cluster/7380/redis.conf
[wxyuan@node1 ~]$ /redis/redis/bin/redis-server /redis/redis/cluster/7381/redis.conf

启动后，使用命令ps -ef|grep redis可查看redis进程。

[wxyuan@node1 ~]$ ps -ef|grep redis
wxyuan     1912      1  0 21:19 ?        00:00:02 /redis/redis/bin/redis-server 192.168.1.101:7380 [cluster]        
wxyuan     1916      1  0 21:19 ?        00:00:02 /redis/redis/bin/redis-server 192.168.1.101:7381 [cluster]

注意：以上步骤，另外两台机器需要做同样的操作

3 创建redis集群

注意：创建集群前，最好关闭防火墙，如果防火墙配置不当，可能出现连接拒绝的错误

创建集群，让上面的实例互相通讯(1表示为每个master分配一个salve)

[wxyuan@node1 src]$ ./redis-trib.rb create --replicas 1 192.168.1.101:7380 192.168.1.101:7381 192.168.1.102:7380 192.168.1.102:7381 192.168.1.103:7380 192.168.1.103:7381

# 这里我们可以看到master节点为192.168.1.101:7380、192.168.1.102:7380、192.168.1.103:7380；其他三个为slave节点，输入yes确认

到此redis集群创建完成。

4. 测试redis集群

在任意一台集群机器上执行如下操作

[wxyuan@node1 ~]$ /redis/redis/bin/redis-cli -h 192.168.1.101 -p 7380 -c
192.168.1.101:7380> set k1 "AA"
OK
192.168.1.101:7380> set k2 "BB"
-> Redirected to slot [449] located at 192.168.1.103:7380
OK
192.168.1.103:7380> get k1
-> Redirected to slot [12706] located at 192.168.1.101:7380
"AA"
192.168.1.101:7380> get k2
-> Redirected to slot [449] located at 192.168.1.103:7380
"BB"
192.168.1.103:7380>
