redis5.09 集群安装1. 环境准备

1. 环境准备

redis采用redis5.0.9版本

1.1 环境配置

No 主机名 目录假定 作用 IP Port
1 redis1 /usr/local/redis bin目录 192.168.8.110
2 /usr/local/redis_cluster/7000/redis.conf 集群端口 7000
3 /usr/local/redis_cluster/7001/redis.conf 集群端口 7001
4 /usr/local/redis_cluster/7002/redis.conf 集群端口 7002
5 redis2 /usr/local/redis bin目录 192.168.8.111
6 /usr/local/redis_cluster/7003/redis.conf 集群端口 7003
7 /usr/local/redis_cluster/7004/redis.conf 集群端口 7004
8 /usr/local/redis_cluster/7005/redis.conf 集群端口 7005

2 环境安装

2.1 hostname

[root@base1 ~]# hostnamectl set-hostname redis1 --static
[root@base2 ~]# hostnamectl set-hostname redis2 --static

需要重新启动操作系统

2.2 网络设置

[root@my1 ~]# vi /etc/sysconfig/network-scripts/ifcfg-ens33
[root@my2 ~]# vi /etc/sysconfig/network-scripts/ifcfg-ens33
[root@my3 ~]# vi /etc/sysconfig/network-scripts/ifcfg-ens33
BOOTPROTO="static" #dhcp改为static 
ONBOOT="yes" #开机启用本配置
IPADDR=192.168.8.110 #静态IP 192.168.8.111
GATEWAY=192.168.8.2 #默认网关
NETMASK=255.255.255.0 #子网掩码
DNS1=114.114.114.114 #DNS 配置
DNS2=8.8.8.8 #DNS 配置

$# service network restart

2.3 工具安装

yum install net-tools
yum install tree

3 Redis安装

3.1 redis依赖安装

yum -y install gcc automake autoconf libtool make

3.2 下载redis源文件，并解压

yum install wget
wget http://download.redis.io/releases/redis-5.0.9.tar.gz
tar xvzf redis-5.0.9.tar.gz

3.3 安装redis

cd redis-5.0.9
make PREFIX=/usr/local/redis install

将 redis-trib.rb 复制到 /usr/local/bin 目录下

cd src 
cp redis-trib.rb /usr/local/bin/

3.4 创建 Redis 节点,

首先在 redis1 机器上 创建 redis_cluster 目录

mkdir /usr/local/redis_cluster
mkdir /usr/local/redis_cluster/7000 /usr/local/redis_cluster/7001 /usr/local/redis_cluster/7002

cp redis.conf /usr/local/redis_cluster/7000 
cp redis.conf /usr/local/redis_cluster/7001 
cp redis.conf /usr/local/redis_cluster/7002

vi /usr/local/redis_cluster/7000/redis.conf
port 7000 //端口7000,7001,7002 
bind 本机ip //默认ip为127.0.0.1 需要改为其他节点机器可访问的ip 否则创建集群时无法访问对应的端口，无法创建集群 
daemonize yes //redis后台运行 
pidfile /var/run/redis_7000.pid //pidfile文件对应7000,7001,7002 
cluster-enabled yes //开启集群 把注释#去掉 
cluster-config-file nodes_7000.conf //集群的配置 配置文件首次启动自动生成 7000,7001,7002 把注释#去掉 
cluster-node-timeout 15000 //请求超时 默认15秒，可自行设置  把注释#去掉 
appendonly yes //aof日志开启 有需要就开启，它会每次写操作都记录一条日志

其次在 redis2 机器上 创建 redis_cluster 目录

mkdir /usr/local/redis_cluster
mkdir /usr/local/redis_cluster/7003 /usr/local/redis_cluster/7004 /usr/local/redis_cluster/7005

cp redis.conf /usr/local/redis_cluster/7003 
cp redis.conf /usr/local/redis_cluster/7004 
cp redis.conf /usr/local/redis_cluster/7005

vi /usr/local/redis_cluster/7000/redis.conf
port 7003 //端口7003,7004,7005 
bind 本机ip //默认ip为127.0.0.1 需要改为其他节点机器可访问的ip 否则创建集群时无法访问对应的端口，无法创建集群 
daemonize yes //redis后台运行 
pidfile /var/run/redis_7003.pid //pidfile文件对应7003,7004,7005 
cluster-enabled yes //开启集群 把注释#去掉 
cluster-config-file nodes_7003.conf //集群的配置 配置文件首次启动自动生成 7003,7004,7005 把注释#去掉 
cluster-node-timeout 15000 //请求超时 默认15秒，可自行设置  把注释#去掉 
appendonly yes //aof日志开启 有需要就开启，它会每次写操作都记录一条日志

3.5 启动各个节点

redis1

cd /usr/local/redis
./bin/redis-server ../redis_cluster/7000/redis.conf 
./bin/redis-server ../redis_cluster/7001/redis.conf 
./bin/redis-server ../redis_cluster/7002/redis.conf

redis2

cd /usr/local/redis
./bin/redis-server ../redis_cluster/7003/redis.conf 
./bin/redis-server ../redis_cluster/7004/redis.conf 
./bin/redis-server ../redis_cluster/7005/redis.conf

3.6 检查 redis 启动情况

查看redis端口开启情况

redis1

ps -ef | grep redis
netstat -tnlp | grep redis
tcp        0      0 192.168.8.110:7000      0.0.0.0:*               LISTEN      1627/./bin/redis-se

redis2

ps -ef | grep redis
netstat -tnlp | grep redis
tcp        0      0 192.168.8.111:17003     0.0.0.0:*               LISTEN      1655/./bin/redis-se

3.7 开启两台机器的防火墙

redis1

firewall-cmd --zone=public --add-port=7000-7002/tcp --permanent
firewall-cmd --zone=public --add-port=17000-17002/tcp --permanent
firewall-cmd --reload
firewall-cmd --zone=public --list-ports

redis2

firewall-cmd --zone=public --add-port=7003-7005/tcp --permanent
firewall-cmd --zone=public --add-port=17003-17005/tcp --permanent
firewall-cmd --reload
firewall-cmd --zone=public --list-ports

4 集群

4.1 创建集群

redis1

./bin/redis-cli --cluster create --cluster-replicas 1 192.168.8.110:7000 192.168.8.110:7001 192.168.8.110:7002 192.168.8.111:7003 192.168.8.111:7004 192.168.8.111:7005

输入 yes 即可，然后出现如下内容，说明安装成功

集群创建后，主从分配如下表：

主从 IP Port
Master 192.168.8.110 7000
Master 192.168.8.110 7001
Master 192.168.8.111 7003
Slave 192.168.8.110 7002
Slave 192.168.8.111 7004
Slave 192.168.8.111 7005

4.2 集群验证

在第一台机器上连接集群的7000端口的节点，在另外一台连接7003节点，连接方式为

redis1

./bin/redis-cli -h 192.168.8.110 -c -p 7000
192.168.8.110:7000> set hello world
OK

然后在另外一台7005端口，查看 key 为 hello 的内容， get hello ，执行结果如下：

redis2

./bin/redis-cli -h 192.168.8.111 -c -p 7005
192.168.8.111:7005> get hello
-> Redirected to slot [866] located at 192.168.8.110:7000
"world"
