Opcache导致php-fpm崩溃nginx返回502
这篇文章主要介绍了Opcache导致php-fpm崩溃nginx返回502的解决方法,十分实用,需要的朋友可以参考下
我这个博客为了提高运行效率在vps上装了opcache扩展,结果发现有个页面返回502,其他页面正常。
检查了php-fpm日志,发现是php-fpm子进程不知道为什么会崩溃,然后把opcache关了就正常。中间折腾的过程就不提了,总之最后发现应该是和另外一个扩展 zend guard冲突导致的,搞笑的是,只要我把php.ini中[zend guard] 配置段放在[zend opcache]后面就正常了。
不想继续深究了,如果你对php底层熟悉,可以为我解惑。

How to configure an Nginx domain name on a cloud server: Create an A record pointing to the public IP address of the cloud server. Add virtual host blocks in the Nginx configuration file, specifying the listening port, domain name, and website root directory. Restart Nginx to apply the changes. Access the domain name test configuration. Other notes: Install the SSL certificate to enable HTTPS, ensure that the firewall allows port 80 traffic, and wait for DNS resolution to take effect.

Starting an Nginx server requires different steps according to different operating systems: Linux/Unix system: Install the Nginx package (for example, using apt-get or yum). Use systemctl to start an Nginx service (for example, sudo systemctl start nginx). Windows system: Download and install Windows binary files. Start Nginx using the nginx.exe executable (for example, nginx.exe -c conf\nginx.conf). No matter which operating system you use, you can access the server IP

The methods that can query the Nginx version are: use the nginx -v command; view the version directive in the nginx.conf file; open the Nginx error page and view the page title.

How to confirm whether Nginx is started: 1. Use the command line: systemctl status nginx (Linux/Unix), netstat -ano | findstr 80 (Windows); 2. Check whether port 80 is open; 3. Check the Nginx startup message in the system log; 4. Use third-party tools, such as Nagios, Zabbix, and Icinga.

You can query the Docker container name by following the steps: List all containers (docker ps). Filter the container list (using the grep command). Gets the container name (located in the "NAMES" column).

To get Nginx to run Apache, you need to: 1. Install Nginx and Apache; 2. Configure the Nginx agent; 3. Start Nginx and Apache; 4. Test the configuration to ensure that you can see Apache content after accessing the domain name. In addition, you need to pay attention to other matters such as port number matching, virtual host configuration, and SSL/TLS settings.

Steps to create a Docker image: Write a Dockerfile that contains the build instructions. Build the image in the terminal, using the docker build command. Tag the image and assign names and tags using the docker tag command.

Docker container startup steps: Pull the container image: Run "docker pull [mirror name]". Create a container: Use "docker create [options] [mirror name] [commands and parameters]". Start the container: Execute "docker start [Container name or ID]". Check container status: Verify that the container is running with "docker ps".
