[linux] multiple redis instances on a host 啟動多個 Redis 實例在同一台機器

multiple redis instances on a host

怎麼在同一台Linux的host運行多個 redis host呢?

centos 下

cp /etc/redis.conf /etc/redis-dev.conf

修改 /etc/redis-dev.conf

vim /etc/redis-dev.conf

修改部份

logfile "/var/log/redis/redis-dev.log"

dir "/var/lib/redis-dev"

pidfile "/var/run/redis/redis-dev.pid"

port 6380

建立資料夾

mkdir -p /var/lib/redis-dev

chown redis:redis /var/lib/redis-dev

因為使用 systemd

cp /usr/lib/systemd/system/redis.service /usr/lib/systemd/system/redis-dev.service

修改 /usr/lib/systemd/system/redis-dev.service

[Service]

ExecStart=/usr/bin/redis-server /etc/redis-dev.conf --daemonize no

ExecStop=/usr/bin/redis-shutdown redis-dev

Enable redis-dev

systemctl enable redis-dev

啟動

service redis-dev start

看一下是否有正常啟動

lsof -i:6379

lsof -i:6380

# ps aux | grep redis
