在 Centos 上运行多个 Redis 实例 [英] Running multiple instance of Redis on Centos

问题描述

我想在 Centos 7 上运行多个 Redis 实例.谁能指出我正确的链接或在此处发布步骤.

我在谷歌上搜索了相关信息，但没有找到任何相关信息.

解决方案

您可以在一台机器上使用不同的端口运行多个 Redis 实例.如果您对此感到担忧，那么您可以按照以下步骤操作.

<块引用>

通过安装第一个 Redis 实例，它默认监听 localhost:6379.

为第二个实例创建一个新的工作目录

默认Redis实例使用/var/lib/redis作为它的工作目录，如果你没有，转储的内存内容保存在这个目录下，名称为dump.rdb更改.为了避免运行时冲突，我们需要创建一个新的工作目录.

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

创建一个新的配置文件

cp/etc/redis.conf/etc/redis2.confchown redis/etc/redis2.conf

编辑以下设置以避免冲突

日志文件/var/log/redis/redis2.log"目录/var/lib/redis2"pidfile "/var/run/redis/redis2.pid"6380端口

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

[服务]ExecStart=/usr/bin/redis-server/etc/redis2.conf --daemonize noExecStop=/usr/bin/redis-shutdown redis2

设置为开机启动

systemctl enable redis2

开始第二个Redis

service redis2 start

检查状态

lsof -i:6379lsof -i:6380

通过执行此操作，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.

I want to run multiple instance of Redis on Centos 7. Can anyone point me to proper link or post steps here.

I googled for the information but I didn't find any relevant information.

解决方案

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.

By installing the first Redis instance, it listens on localhost:6379 by default.

For Second Instance create a new working directory

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/

Generate configurations

Create a new configuration file by copying /etc/redis.conf

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

Edit following settings to avoid conflicts

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

Create service file

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

Modify the settings under Service section

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

Set to start with boot

systemctl enable redis2

Start 2nd Redis

service redis2 start

Check Status

lsof -i:6379
lsof -i:6380

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