Linux redis-Sentinel configuration details

download

Download address: https://redis.io/download

Execute the download in the /usr/local/src directory.

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

Install

Unzip it to the /usr/local/src directory and put the source package.

tar xzf redis-3.2.8.tar.gz

Create the directory /usr/local/redis:

make dir /usr/local/redis

Enter the source directory:

cd /usr/local/src/redis-3.2.8

Then execute the following make command to compile and install it to the directory /usr/local/redis/ (where the executable file is placed).

make PREFIX=/usr/local/redis install

Soft connection

The program is soft-linked to the bin directory for direct execution.

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

Configuration Files

Copy the configuration files. There are sentinel.conf and redis.conf files in the source code package. Copy them to the /etc/redis/ directory. If there are multiple instances, it is recommended to rename them. For example, the redis port used in this instance is 7021, and the sentinel port is 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 configuration

Modify the following configuration parameters:

port 6379
daemonize yes
#requirepass 123456
#masterauth 123456

The daemonize attribute is changed to yes (background run).

redis_slave_6380.conf configuration :

Modify the following configuration parameters:

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

The configuration of other slaves is the same as this one.

sentinel_26379.conf configuration

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 configuration

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

start up

Start the services in sequence.

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

Check whether all processes have been started

[root@iZj6cqZ redis]# ps -ef | grep redis
