php-fpm经常出现502解决方法

最近nginx经常502,解决502最好的办法就是重启php-fpm。
手动去重启还是比较麻烦的事情,最好的就是扔到shell里去。

vim restart-php-fpm.sh

#!/bin/shSERVICE=\'php-fpm\'#if ps ax | grep -v grep | grep $SERVICE > /dev/nullif netstat -anp | grep 9000 > /dev/nullthen    echo \"$SERVICE service running, everything is fine\"else    echo \"$SERVICE is not running\"    service php-fpm startfi
Copy after login
本地虚拟机测试了一下,可行,扔到服务器上去,结果发现502的时候并未php-fpm没有进程,而是php-fpm僵死。
所以走了另外一种方案:

vim restart-php-fpm.sh

#!/bin/bashMY_URL=\"http://www.webyang.net\"RESULT=\'curl -I $MY_URL | grep \"HTTP/1.1 502\"\' if [ -n \"$RESULT\" ]; then#如果502则会执行这里的内容,随便加或改killall -9 php-cgiservice php-fpm restartfi
Copy after login
这样的话,还是手动的,如果需要自动,自己添加到crontab里去。
chmod 755 restart-php-fpm.sh
运行crontab -e
设置restart-php-fpm.sh 每一分钟自动执行一次(时间可以按自己要求调)
*/1 * * * * /home/restart-php-fpm.sh
查看设置成功还是失败
crontab -l

或者写一个shell死循环,隔一个时间段去执行即可。

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

Describe the SOLID principles and how they apply to PHP development. Describe the SOLID principles and how they apply to PHP development. Apr 03, 2025 am 12:04 AM

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.
