Linux redis-Sentinel配置

语言: CN / TW / HK

下载地址: https://redis.io/download

在/usr/local/src目录下执行下载。

wget http://download.redis.io/releases/redis-3.2.8.tar.gz

安装

解压到/usr/local/src目录,放源码包。

tar xzf redis-3.2.8.tar.gz

创建目录/usr/local/redis:

make dir /usr/local/redis

进入源码目录:

cd /usr/local/src/redis-3.2.8

然后执行下面make命令编译安装到目录/usr/local/redis/ (放执行文件)。

make PREFIX=/usr/local/redis install

软连接

程序做软连接到bin目录,方便直接执行。

ln -s /usr/local/redis/bin/redis-cli /usr/local/bin/redis-cli
ln -s /usr/local/redis/bin/redis-sentinel /usr/local/bin/redis-sentinel
ln -s /usr/local/redis/bin/redis-server /usr/local/bin/redis-server

配置文件

复制配置文件,在源码包里有sentinel.conf和redis.conf文件,复制到/etc/redis/目录下,如果有多个实例,建议改名,如本实例用的redis端口是7021,sentinel是17021:

mkdir /etc/redis
cp /usr/local/src/redis-3.2.8/redis.conf /etc/redis/redis_6379.conf 
cp /usr/local/src/redis-3.2.8/sentinel.conf /etc/redis/sentinel_26379.conf

redis_master_6379.conf配置

修改配置以下参数:

port 6379
daemonize yes
#requirepass 123456
#masterauth 123456

其中,daemonize属性改为yes(后台运行)。

redis_slave_6380.conf 配置:

修改配置以下参数:

port 6380
daemonize yes
#requirepass yingjun
slaveof 192.168.248.128 6379
masterauth 123456

其他slave配置同此配置。

sentinel_26379.conf 配置

port 23791
daemonize yes
logfile "/var/log/sentinel_63791.log"
#master-1
sentinel monitor master-1 192.168.248.128 6379 2
#sentinel auth-pass master-1 yingjun

sentinel_26380.conf 配置

port 23780
daemonize yes
logfile "/var/log/sentinel_63780.log"
#master-1
sentinel monitor master-1 192.168.248.128 6379 2
#sentinel auth-pass master-1 yingjun

启动

顺序依次启动服务。

redis-server /etc/redis/redis_master_6379.conf
redis-server /etc/redis/redis_slave_6380.conf  
redis-sentinel /etc/redis/sentinel_26379.conf
redis-sentinel /etc/redis/sentinel_26380.conf

查看进程是否都已经启动
