安装redis
官网下载redis,解压缩，让进目录，make完事。[root@meng data]# tar redis-3.2.12.tar.gz
[root@meng data]# cd redis-3.2.12 [root@meng redis-3.2.12]# make [root@meng redis-3.2.12]# pwd /data/redis-3.2.12 [root@meng redis-3.2.12]# mkdir redis6380 [root@meng redis-3.2.12]# pwd /data/redis-3.2.12 [root@meng redis-3.2.12]# cp -rf redis.conf /data/redis6380/ [root@meng src]# pwd /data/redis-3.2.12/src [root@meng src]# cp src/redis-server /data/redis6380/ [root@meng redis6380]# pwd /data/redis6380 [root@meng redis6380]# grep '^[^$|#;]' redis.conf > redis.conf2 [root@meng redis6380]# mv redis.conf redis.confbak [root@meng redis6380]# mv redis.conf2 redis.conf [root@meng redis6380]# ll total 5124 -rw-r--r-- 1 root root 1170 Sep 4 20:24 redis.conf -rw-r--r-- 1 root root 46695 Sep 4 20:16 redis.confbak -rwxr-xr-x 1 root root 5192400 Sep 4 20:16 redis-server [root@meng redis6380]# vim redis.conf [root@meng redis6380]# ./redis-server redis.conf _._ _.-``__ ''-._ _.-`` `. `_.

redis集群
脚本创建6个节点，并修改配置文件
[root@meng data]# more cluster.sh #!/bin/bash rm -rf /data/700* for no in 0 1 2 3 4 5;do cp -r redis6380/ 700$no;done for no in 0 1 2 3 4 5;do rm -rf 700$no/dump.rdb;done for no in 0 1 2 3 4 5 do cd /data/700$no sed -i "s/port 6380/port 700$no/g" redis.conf echo "cluster-enabled yes" >> redis.conf echo "cluster-config-file nodes.conf" >> redis.conf echo "cluster-node-timeout 5000" >> redis.conf sed -i "s/appendonly no/appendonly yes/g" redis.conf sed -i "s/redis_6380.pid/redis_700$no.pid/g" redis.conf sed -i "/^dir/d" redis.conf echo 'dir "./"' >> redis.conf done [root@meng data]#
启动6个节点：
[root@meng data]# for no in 0 1 2 3 4 5;do cd /data/700$no && ./redis-server ./redis.conf;done [root@meng data]# netstat -lnpt Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 0.0.0.0:17003 0.0.0.0:* LISTEN 2536/./redis-server tcp 0 0 0.0.0.0:17004 0.0.0.0:* LISTEN 30492/./redis-serve tcp 0 0 0.0.0.0:17005 0.0.0.0:* LISTEN 30494/./redis-serve tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 1199/sshd tcp 0 0 0.0.0.0:7000 0.0.0.0:* LISTEN 2504/./redis-server tcp 0 0 0.0.0.0:7001 0.0.0.0:* LISTEN 30486/./redis-serve tcp 0 0 0.0.0.0:25 0.0.0.0:* LISTEN 23187/master tcp 0 0 0.0.0.0:7002 0.0.0.0:* LISTEN 30488/./redis-serve tcp 0 0 0.0.0.0:7003 0.0.0.0:* LISTEN 2536/./redis-server tcp 0 0 0.0.0.0:7004 0.0.0.0:* LISTEN 30492/./redis-serve tcp 0 0 0.0.0.0:7005 0.0.0.0:* LISTEN 30494/./redis-serve tcp 0 0 0.0.0.0:17000 0.0.0.0:* LISTEN 2504/./redis-server tcp 0 0 0.0.0.0:17001 0.0.0.0:* LISTEN 30486/./redis-serve tcp 0 0 0.0.0.0:17002 0.0.0.0:* LISTEN 30488/./redis-serve tcp6 0 0 :::80 :::* LISTEN 1671/docker-proxy-c tcp6 0 0 :::25 :::* LISTEN 23187/master
创建集群脚本是ruby写的，需要系统安装高于2.2.以上版本的ruby,ruby版本低会报以下错误。
创建redis集群报错 /usr/share/rubygems/rubygems/core_ext/kernel_require.rb:55:in `require': cannot load suc
升级ruby步骤：
1、sudo yum install curl 安装curl 2、下载rvm curl -sSL https://get.rvm.io | bash -s stable 3、查找配置文件 find / -name rvm.sh 4、配置文件生效 source /etc/profile.d/rvm.sh 5、下载rvm依赖 rvm requirements 6、查看rvm库ruby版本 rvm list known 7、安装ruby指定版本 rvm install ruby-2.4.1 8、使用ruby版本默认 rvm use 2.4.1 default 9、gem install redis
然后从新创建集群输入yes成功，查看集群节点状态。有master和slave
