1. Reference:Based on Alibaba Cloud’s ECS and RDS, the personal blog migration has been upgraded to: Docker (based on budget considerations, ultimately not realized), LNMP (CentOS 7.7, Nginx 1.16, MySQL 5.7, PHP 7.4), the process of HTTPS , the previous environment was based on the automatic installation of OneInstack. PHP version 7.4 is no longer eligible for Shopify applications. It needs to be upgraded to version 8.1, trying to be consistent with the local environment. as shown in Figure 1

8. Reference:In Alibaba Cloud ECS, CentOS 7 migration (replace) to Alibaba Cloud Linux 3 . Open URL:https://oneinstack.com/auto/, based on the automatic installation of OneInStack, LNMP, PHP version 8.1, and copy the installation command are selected, as shown in Figure 6
9. After starting the ECS instance, enter the Alibaba Cloud Linux server based on Putty, paste the installation command, and then keep it stuck at –php_extensions fileinfo. Press Ctrl + C to stop the installation process. as shown in Figure 7
[root@iZ23wv7v5ggZ ~]# wget -c http://mirrors.linuxeye.com/oneinstack-full.tar.gz && tar xzf oneinstack-full.tar.gz && ./oneinstack/install.sh --nginx_option 1 --php_option 11 --phpcache_option 1 --php_extensions imagick,fileinfo,imap,ldap,redis,mongodb --pureftpd --redis
10. In the installation command, the PHP extension only keeps Imagick, Redis, and other extensions will be installed on demand. If the components are not installed before, the subsequent installation will be supplemented, and the unified entrance is ./install.sh . Still stuck at –php_extensions FileInfo, confirm that OneInStack does not support the installation of extended FileInfo under PHP 8.1. Next, try to install this extension yourself.
[root@iZ23wv7v5ggZ ~]# wget -c http://mirrors.linuxeye.com/oneinstack-full.tar.gz && tar xzf oneinstack-full.tar.gz && ./oneinstack/install.sh --nginx_option 1 --php_option 11 --phpcache_option 1 --php_extensions imagick,redis --pureftpd --redis

13. My ECS memory is 1 GB configuration. Compiling FileInfo takes up a lot of memory, which is the direct cause of incompilation. It was finally decided to improve the configuration of the ECS, and the memory was increased to 2 GB. Reference:When compiling and installing PHP extension FileInfo in Alibaba Cloud ECS, the solution is stuck (improve memory configuration)
