[root@resdis-1 ~]# mkdir soft #軟件安裝包
[root@resdis-1 ~]# mkdir -p /app/redis #redis配置地址
源碼安裝
下載地址：http://redis.io/download
下載穩(wěn)定版5.0.10
[root@resdis-1 ~]# cd soft/
[root@resdis-1 soft]# wget https://download.redis.io/releases/redis-5.0.10.tar.gz
解壓贷洲、編譯牵寺、安裝
1.安裝依賴
[root@resdis-1 soft]# yum -y install gcc gcc-c++ libstdc++-devel
2.解壓、編譯
[root@resdis-1 soft]# tar -xzvf redis-5.0.10
[root@resdis-1 soft]# cd redis-5.0.10
[root@resdis-1 redis-5.0.10]# make
3.編譯完安裝
[root@resdis-1 redis-5.0.10]# cd src/
[root@resdis-1 src]# make install
集群安裝
每臺(tái)機(jī)器都要執(zhí)行
[root@resdis-1 ~]# mkdir -p /app/redis/cluster/
[root@resdis-1 ~]# cp ~/soft/redis-5.0.10/redis.conf /app/redis/cluster/
[root@resdis-1 ~]# vi /app/redis/cluster/redis.conf
修改內(nèi)容如下
#bind 127.0.0.1
protected-mode no
port 7000
daemonize yes //redis后臺(tái)運(yùn)行
pidfile /var/run/redis_7000.pid
cluster-enabled yes //開啟集群
cluster-config-file nodes_7000.conf //集群的配置
cluster-node-timeout 15000 //請(qǐng)求超時(shí) 默認(rèn)15秒恩脂，可自行設(shè)置
appendonly yes //aof日志開啟帽氓，它會(huì)每次寫操作都記錄一條日志
appendfilename "appendonly7000.aof"
dbfilename dump7000.rdb
編輯啟動(dòng)腳本
[root@resdis-1 cluster]# cd /app/redis/cluster/
[root@resdis-1 cluster]# vi start.sh
#!/bin/bash
redis-server redis.conf
停止腳本
[root@resdis-6 cluster]# vi stop.sh
#!/bin/bash
kill `ps -ef | grep redis-server| grep 7000 | awk '{print $2}'`
啟動(dòng)服務(wù)并查看
[root@resdis-1 cluster]# ./start.sh
[root@resdis-1 cluster]# ps -ef|grep redis
root 2521 1 0 21:47 ? 00:00:00 redis-server *:7000 [cluster]
