redis 4.0 一主多从 哨兵集群搭建

1.准备工作：

操作系统：centos 7 minal x86_64 

ip地址：192.168.30.59

redis 4.0：http://download.redis.io/releases/redis-4.0.11.tar.gz

安装编译工具：yum install gcc make tcl -y

2.编译安装：

make && make test

make install

3.配置主从集群：

mkidr /opt/{7001..7003}

分别启动redis服务，并测试检查：

redis-server /opt/7001/7001.conf

redis-server /opt/7002/7002.conf

redis-server /opt/7003/7003.conf

登陆查看集群信息：

redis-cli -p 7001

info replication

set aa 123

set name "123"

get aa

get name

keys *

其他类似

测试没得问题 主从集群就搭建成功

 

4.搭建哨兵模式

第一种：单个哨兵：

protected-mode no
daemonize yes
logfile "/opt/7001/sentinel_7001.log"
port 26380
dir "/tmp"
sentinel deny-scripts-reconfig yes
sentinel monitor mymaster 192.168.30.59 7001 1
sentinel auth-pass mymaster 123456
sentinel config-epoch mymaster 1
sentinel leader-epoch mymaster 1

启动哨兵进行测试：

redis-sentinel /opt/7001/sentinel_7001.conf

将7001shutdown然后查看哨兵日志变化

自动将从节点切换为主节点，且7001重启动后自动切换成从节点

说明哨兵生效

第二种：多个哨兵

sentinel monitor mymaster 192.168.30.59 7001 2

测试同上
