使用./install_server.sh安装Redis时遇systemd相关错误求助

Hey there, I've run into this exact issue before—let's get your Redis set up properly with systemd since your system doesn't use the old sysvinit/upstart that the install_server.sh script was built for. Here's a step-by-step breakdown:

1. Locate the systemd service example file #

You're already in the utils directory of your Redis source code, which has a pre-made systemd service template. Look for redis-server.service (it should be right there alongside the install_server.sh script).

2. Copy and customize the service file #

First, copy the template to systemd's service directory (where systemd looks for service definitions):

sudo cp redis-server.service /etc/systemd/system/

Next, open the copied file to adjust paths to match your setup—this is crucial:

sudo vim /etc/systemd/system/redis-server.service

You'll need to tweak these key fields:

• ExecStart: Point this to your compiled redis-server binary. If you built Redis from source, it's likely in the src folder of your Redis source (e.g., /path/to/redis-source/src/redis-server /etc/redis/redis.conf). Don't forget to include the path to your redis.conf file too.
• PIDFile: This should match the pidfile setting in your redis.conf (default is /var/run/redis_6379.pid).
• WorkingDirectory: Set this to your Redis data directory (common choices are /var/lib/redis or the data folder in your source).
• User/Group: Make sure these match the user/group you want Redis to run as (many setups use a dedicated redis user—create it first if you haven't with sudo useradd -r redis).

3. Prepare necessary directories (if missing) #

If you're using standard paths like /var/lib/redis for data and /var/log/redis for logs, create them and set proper permissions:

sudo mkdir -p /var/lib/redis /var/log/redis
sudo chown redis:redis /var/lib/redis /var/log/redis
sudo chmod 770 /var/lib/redis /var/log/redis

4. Enable and start the Redis service #

Reload systemd to recognize the new service file, then enable it to start on boot, and launch it:

sudo systemctl daemon-reload
sudo systemctl enable redis-server
sudo systemctl start redis-server

5. Verify everything works #

Check the service status to confirm it's running:

sudo systemctl status redis-server

You can also test connectivity with Redis CLI:

redis-cli ping

If you get PONG back, you're good to go!
