CentOS7.2 安装redis 3.0.6集群

发布时间：2020-12-13 14:00:40 所属栏目：Linux 来源：网络整理

导读：1.环境确认 a.系统版本查看 [hadoop@p168 ~]$ cat /etc/redhat-release CentOS Linux release 7.2.1511 (Core)? b.安装依赖 [hadoop@p168 ~]$?sudo yum?-y?install?tcl?ruby tree? ? 2.安装redis 3.0.6 [hadoop@p168 ~]#cd?/usr/local/ [hadoop@p168 ~]#wget

1.环境确认

a.系统版本查看

[hadoop@p168 ~]$ cat /etc/redhat-release

CentOS Linux release 7.2.1511 (Core)?

b.安装依赖

[hadoop@p168 ~]$?sudo yum?-y?install?tcl?ruby tree?

2.安装redis 3.0.6

[hadoop@p168 ~]#cd?/usr/local/

[hadoop@p168 ~]#wget??

[hadoop@p168 ~]#tar??xzf?redis-stable.tar.gz

[hadoop@p168 ~]#cd?redis-stable

[hadoop@p168 ~]#make

[hadoop@p168 ~]#make?test

[hadoop@p168 ~]#make?install

3.建立节点配置目录

[hadoop@p168 ~]#mkdir /etc/redis

[hadoop@p168 ~]#mkdir /etc/redis/7000

4.建立节点配置文件

a.配置7000节点,先复制redis-server与初始配置文件redis.conf,然后修改redis.conf,使其适合集群

[hadoop@p168 ~]#cp?/usr/local/redis-stable/src/redis-server ?/usr/local/redis-stable/redis.conf /etc/redis/7000

修改redis.conf,主要修改内容如下:

[hadoop@p168 ~]#vim?/etc/redis/7000/redis.conf

#/etc/redis/7000/redis.conf

port?7000

daemonize????yes?

pidfile??/var/run/redis_7000.pid

cluster-enabled?yes

cluster-config-file?nodes.conf

logfile?"/var/log/redisd7000.log"

dir?/etc/redis/7000/

cluster-node-timeout?5000

appendonly?yes

b.复制其他节点配置文件

#生成7001配置,其他类似

cp?-r?7000 7001

sed?-i?"s/7000/7001/g"?7001/redis.conf

cat??7001/redis.conf?|grep?7001

5.配置节点开机启动

修改redisd7000的启动脚本,7001~7005类似

[hadoop@p168 ~]#cp?/usr/local/redis-stable/utils/redis_init_script?/etc/init.d/redisd7000

[hadoop@p168 ~]#vim??/etc/init.d/redisd7000

#!/bin/sh

#chkconfig:????2345?90?10

#description:??Redis?is?a?persistent?key-value?database

#?Simple?Redis?init.d?script?conceived?to?work?on?Linux?systems

#?as?it?does?use?of?the?/proc?filesystem.

REDISPORT=7000

#EXEC=/usr/local/bin/redis-server

EXEC=/etc/redis/${REDISPORT}/redis-server

CLIEXEC=/usr/local/bin/redis-cli

PIDFILE=/var/run/redis_${REDISPORT}.pid

#CONF="/etc/redis/${REDISPORT}.conf"

CONF="/etc/redis/${REDISPORT}/redis.conf"

主要修改内容包括如下三点:

a.加入前三行即

#!/bin/sh

#chkconfig:????2345?90?10

#description:??Redis?is?a?persistent?key-value?database

b.修改端口,即

REDISPORT=7000

c.指定EXEC与CONF即

EXEC=/etc/redis/${REDISPORT}/redis-server

CONF="/etc/redis/${REDISPORT}/redis.conf"

其他的不动,略

复制生成其他启动脚本

#生成7001脚本,其他类似

cp /etc/init.d/redisd7000?/etc/init.d/redisd7001

sed?-i?"s/7000/7001/g"?/etc/init.d/redisd7001

cat???/etc/init.d/redisd7001?|grep?7001

#设置为开机自启动服务器,其他服务类似

[hadoop@p168 ~]#chkconfig?redisd7000?on

确认配置文件,重启前应该是如下状态

[?~]#?ls?/etc/init.d/?|grep?redis

redisd7000

redisd7001

redisd7002

redisd7003

redisd7004

redisd7005

注:以上文件是6个服务的自动启动脚本

[?~]#?tree?/etc/redis

/etc/redis

├──?7000

│???├──?redis.conf

│???└──?redis-server

├──?7001

│???├──?redis.conf

│???└──?redis-server

├──?7002

│???├──?redis.conf

│???└──?redis-server

├──?7003

│???├──?redis.conf

│???└──?redis-server

├──?7004

│???├──?redis.conf

│???└──?redis-server

├──?7005

│???├──?redis.conf

│???└──?redis-server

注:以上目录是各服务器的redis-server可执行程序与其配置文件,若没有tree命令,先 yum install -y tree

[hadoop@p168 ~]# reboot

重启以后服务应该就启动了,若有需要可以用如下命令来启动或停止服务了

service?redisd7000?start

service?redisd7000?stop

6.安装redis接口

#rubygems.org被墙,换ruby.taobao.org

gem?sources?--remove?

gem?sources?-a?

gem?install?redis

7.建立集群

[?redis-stable]#?/usr/local/redis-stable/src/redis-trib.rb??create?--replicas?1?192.168.1.161:7000?192.168.1.161:7001?192.168.1.161:7002?192.168.1.161:7003?192.168.1.161:7004?192.168.1.161:7005

有错误的话,修复集群

9.打开防火墙端口

[?~]#?firewall-cmd?--zone=public?--add-port=7000-7005/tcp?--permanent

success

[<a href="mailto:root@p161" target="_blank">root@p161?~]#firewall-cmd?--reload

success

10.访问测试

11.python测试

先安装pip install redis-py-cluster

注意在集群中 pip install redis安装的redis会报错!!!

from rediscluster import StrictRedisCluster
startup_nodes = [{"host": "192.168.1.161","port": "7000"}]
rc = StrictRedisCluster(startup_nodes=startup_nodes,decode_responses=True)
rc.set("blog","http://blog.csdn.net/dgatiger")
print rc.get('blog')
