推荐答案

您可以在单台计算机上使用不同的端口运行Redis的多个实例.如果这与您有关，则可以按照以下步骤操作.

You can run multiple instances of Redis using different ports on a single machine. If this what concerns you then you can follow the below steps.

通过安装第一个Redis实例，默认情况下它会监听localhost:6379.

为第二实例创建一个新的工作目录

默认Redis实例使用/var/lib/redis作为其工作目录，如果不进行更改，转储的内存内容将以名称dump.rdb保存在该目录下.为了避免运行时冲突，我们需要创建一个新的工作目录.

The default Redis instance uses /var/lib/redis as its working directory, dumped memory content is saved under this directory with name dump.rdb if you did not change it. To avoid runtime conflicts, we need to create a new working directory.

mkdir -p /var/lib/redis2/
chown redis /var/lib/redis2/
chgrp redis /var/lib/redis2/

生成配置

通过复制/etc/redis.conf

cp /etc/redis.conf /etc/redis2.conf
chown redis /etc/redis2.conf

编辑以下设置以避免冲突

logfile "/var/log/redis/redis2.log"
dir "/var/lib/redis2"
pidfile "/var/run/redis/redis2.pid"
port 6380

创建服务文件

cp /usr/lib/systemd/system/redis.service /usr/lib/systemd/system/redis2.service

修改服务"部分下的设置

Modify the settings under Service section

[Service]
ExecStart=/usr/bin/redis-server /etc/redis2.conf --daemonize no
ExecStop=/usr/bin/redis-shutdown redis2

设置为从启动开始

systemctl enable redis2

开始第二次Redis

service redis2 start

检查状态

lsof -i:6379
lsof -i:6380

通过此操作，您可以启动两个Redis服务器.如果您想要更多，请再次重复这些步骤.

By Following this you can start two Redis servers. If you want more repeat the steps again.
