Redis log files are usually located in /var/log/redis/redis-server.log or /
\redis.log. You can view the logs using command line tools such as tail -f redis-server.log. The default log level is "verbose", which can be changed by modifying the redis.conf configuration file. Redis also supports log separation, allowing logging to multiple files.
How to view Redis logs
Redis's logging feature helps users quickly identify problems and resolve errors. Here are the steps to view Redis logs:
1. Find Redis log files
Typically, Redis's log files are located at the following locations:
- Linux/macOS: /var/log/redis/redis-server.log
- Windows: /
\redis.log
2. Use the command line tool to view the log
Open a command line terminal (such as Terminal or PowerShell) and navigate to the directory where the log file resides. Then use the following command to view the log:
<code>tail -f redis-server.log</code>
3. Configure log level
By default, Redis logs at the "verbose" level. You can change the log level by modifying the redis.conf configuration file. Here are some commonly used log levels:
- debug: record all debug information
- verbose: Record all errors, warnings and notification information
- notice: record all non-debug information
- Warning: Record all warnings and error messages
- error: Only error messages are recorded
4. Separation log
Redis also allows you to log logs to multiple files or destinations. For example, you can log the error log to one file and the slow query log to another file.
To enable log detachment in redis.conf, add the following line:
<code>slowlog-log-slower-than 10000 slowlog-max-len 128</code>
This will record all slow queries that have been executed for more than 10 milliseconds. The slow query log will be saved in the /var/log/redis/slow.log file.
The above is the detailed content of How to view redis logs. For more information, please follow other related articles on the PHP Chinese website!

I have a lot of experience in participating in VSCode offline technology exchange activities, and my main gains include sharing of plug-in development, practical demonstrations and communication with other developers. 1. Sharing of plug-in development: I learned how to use VSCode's plug-in API to improve development efficiency, such as automatic formatting and static analysis plug-ins. 2. Practical demonstration: I learned how to use VSCode for remote development and realized its flexibility and scalability. 3. Communicate with developers: I have obtained skills to optimize VSCode startup speed, such as reducing the number of plug-ins loaded at startup and managing the plug-in loading order. In short, this event has benefited me a lot and I highly recommend those who are interested in VSCode to participate.

Linux system restricts user resources through the ulimit command to prevent excessive use of resources. 1.ulimit is a built-in shell command that can limit the number of file descriptors (-n), memory size (-v), thread count (-u), etc., which are divided into soft limit (current effective value) and hard limit (maximum upper limit). 2. Use the ulimit command directly for temporary modification, such as ulimit-n2048, but it is only valid for the current session. 3. For permanent effect, you need to modify /etc/security/limits.conf and PAM configuration files, and add sessionrequiredpam_limits.so. 4. The systemd service needs to set Lim in the unit file
