# **Redis3集群安装** #

# 1. **什么是Redis** #

Redis是目前一个非常优秀的key-value存储系统。和Memcached类似，它支持存储的value类型相对更多，包括string(字符串)、list(链表)、set(集合)、zset(sorted set有序集合)和hash（哈希类型）。

# 2. **为什么要安装Redis3集群** #

Redis3.x支持集群模式，更加可靠！

# 3. **安装Redis3集群（6台Linux）** #

参考文章：[http://blog.csdn.net/myrainblues/article/details/25881535][http_blog.csdn.net_myrainblues_article_details_25881535]

1.下载redis3的稳定版本，下载地址http://download.redis.io/releases/redis-3.2.10.tar.gz

2.上传redis-3.2.10.tar.gz到服务器

3.解压redis源码包

tar -zxvf redis-3.2.10.tar.gz -C /usr/local/src/

4.进入到源码包中，编译并安装redis

cd /usr/local/src/redis-3.2.10/

make && make install

5.报错，缺少依赖的包

6.配置本地YUM源并安装redis依赖的rpm包

yum -y install gcc

7.编译并安装

make && make install

8.报错，原因是没有安装jemalloc内存分配器，可以安装jemalloc或直接输入

9.重新编译安装

make MALLOC=libc && make install

10.用同样的方式在其他的机器上编译安装redis

11.在所有机器的/usr/local/下创建一个redis目录，然后拷贝redis自带的配置文件redis.conf到/usr/local/redis

mkdir /usr/local/redis

cp /usr/local/src/redis-3.2.10/redis.conf /usr/local/redis

12.修改所有机器的配置文件redis.conf

<table> 
 <tbody> 
  <tr> 
   <td> <p>daemonize yes &nbsp;#redis<span style="font-family:'宋体';">后台运行</span></p> <p>cluster-enabled yes &nbsp;#<span style="font-family:'宋体';">开启集群把注释去掉</span></p> <p>appendonly yes &nbsp;#<span style="font-family:'宋体';">开启</span><span style="font-family:Calibri;">aof</span><span style="font-family:'宋体';">日志，它会每次写操作都记录一条日志</span></p> </td> 
  </tr> 
 </tbody> 
</table>

sed -i 's/daemonize no/daemonize yes/' /usr/local/redis/redis.conf

sed -i "s/bind 127.0.0.1/ bind $HOST/" /usr/local/redis/redis.conf

sed -i 's/\# cluster-enabled yes/cluster-enabled yes/' /usr/local/redis/redis.conf

sed -i 's/appendonly no/appendonly yes/' /usr/local/redis/redis.conf

sed -i 's/\# cluster-node-timeout 15000/cluster-node-timeout 5000/' /usr/local/redis/redis.conf

13.启动所有的redis节点

cd /usr/local/redis

redis-server redis.conf

14.查看redis进程状态

ps -ef | grep redis

![1276309-20190701141730396-1005050542.png][]

15.（**只要在一台机器上安装即可**）配置集群：安装ruby和ruby gem工具（redis3集群配置需要ruby的gem工具，类似yum）

yum -y install ruby rubygems

16.使用gem下载redis集群的配置脚本

gem install redis

ruby --version

17.安装RVM

curl -sSL https://rvm.io/mpapis.asc | gpg2 --import -

curl -L get.rvm.io | bash -s stable

source /usr/local/rvm/scripts/rvm

rvm list known

rvm install 2.3.4

\#用ruby的工具安装reids

gem install redis

18.使用脚本配置redis集群

cd /usr/local/src/redis-3.2.10/src/

\#service iptables stop

\#**在第一机器上执行下面的命令**

./redis-trib.rb create --replicas 1 192.168.10.101:6379 192.168.10.102:6379 192.168.10.103:6379 192.168.10.104:6379 192.168.10.105:6379 192.168.10.106:6379

19.测试(别忘加\-c参数)

redis-cli -c -h 192.168.1.13

# 4. **Redis3伪分布式安装（1台Linux）** #

1.下载redis3的稳定版本，下载地址http://download.redis.io/releases/redis-3.2.10.tar.gz

2.上传redis-3.2.10.tar.gz到服务器

3.解压redis源码包

tar -zxvf redis-3.2.10.tar.gz -C /usr/local/src/

4.进入到源码包中，编译并安装redis

cd /usr/local/src/redis-3.2.10/

make && make install

5.在/usr/local/下创建一个redis目录，然后分别在/usr/local/redis目录创建6个文件夹7000,7001,7002,7003,7004,7005然后拷贝redis自带的配置文件redis.conf到这六个目录中

mkdir /usr/local/redis

mkdir /usr/local/redis/\{7000,7001,7002,7003,7004,7005\}

cp /usr/local/src/redis-3.2.10/redis.conf /usr/local/redis/7000

cp /usr/local/src/redis-3.2.10/redis.conf /usr/local/redis/7001

cp /usr/local/src/redis-3.2.10/redis.conf /usr/local/redis/7002

cp /usr/local/src/redis-3.2.10/redis.conf /usr/local/redis/7003

cp /usr/local/src/redis-3.2.10/redis.conf /usr/local/redis/7004

cp /usr/local/src/redis-3.2.10/redis.conf /usr/local/redis/7005

6.分别修改这六个目录中的配置文件

<table> 
 <tbody> 
  <tr> 
   <td> <p>port&nbsp;7000&nbsp;#<span style="font-family:'宋体';">端口要与其所在的文件名一致</span></p> <p>pidfile /var/run/redis-7000.pid &nbsp;#pid要与其所在的文件名一致</p> <p>daemonize yes</p> <p>cluster-enabled yes</p> <p>appendonly yes</p> </td> 
  </tr> 
 </tbody> 
</table>

7.分别进入到这六个目录启动redis进程

cd /usr/local/redis/7000

redis-server redis.conf

cd /usr/local/redis/7001

redis-server redis.conf

cd /usr/local/redis/7002

redis-server redis.conf

cd /usr/local/redis/7003

redis-server redis.conf

cd /usr/local/redis/7004

redis-server redis.conf

cd /usr/local/redis/7005

redis-server redis.conf

HOST=\`ifconfig eth1 | grep "inet addr" | awk -F : '\{print $2\}' | awk '\{print $1\}'\`

sed -i "s/bind 127.0.0.1/bind $HOST/" /usr/local/redis/redis.conf

分别进入几个redis的客户端中设置redis密码

config set masterauth username
    
    config set requirepass passwd
    
    auth username
    
    config rewrite

连接到创建的集群中（-c：参数一定要添加）

/usr/local/src/redis-3.2.10/src/redis-cli -p 7005 -c

停止redis服务

redis-cli -h 192.168.100.101 -a 密码 shutdown

创建集群的命令（初始化执行一次，以后只需要将redis启动就可以了）

/usr/local/src/redis-3.2.10/src/redis-trib.rb  start --replicas  1 127.0.0.1:7000  127.0.0.1:7001  127.0.0.1:7002  127.0.0.1:7003  127.0.0.1:7004  127.0.0.1:7005

查看集群运行状态命令

/usr/local/src/redis-3.2.10/src/redis-trib.rb check 127.0.0.1:7001

    16     if [ -z "$REDIS_ID" ]; then
    17         echo "port [$i] pid [$REDIS_ID] not start"
    18     else
