用 frankenphp+mysql 快速搭建一个高性能的网站-1！ 用 frankenphp+mysql 快速搭建一个高性能的网站-1！ FrankenPHP 是构建在Caddy Web 服务器之上的现代 PHP 应用程序服务器。一、docker安装curl -fsSL https://get.docker.com | sh && ln -s /usr/libexec/docker/cli-plugins/docker-compose /usr/local/bin二、创建目录结构mkdir -p /home/web/{caddy,html,,mysql} touch /home/web/caddy/Caddyfile三、下载源码1、安装wordpresscd /home/web/html/ && mkdir web1 && cd web1 wget -O latest.zip https://cn.wordpress.org/latest-zh_CN.zip unzip latest.zip rm latest.zipecho "define('FS_METHOD', 'direct'); define('WP_REDIS_HOST', 'redis'); define('WP_REDIS_PORT', '6379');" >> /home/web/html/web1/wordpress/wp-config-sample.php2、安装typechocd /home/web/html/ && mkdir web2 && cd web2 cd /home/web/html/web2/ && mkdir typecho && cd typecho wget https://github.com/typecho/typecho/releases/download/v1.2.1/typecho.zip unzip typecho.zip rm typecho.zipecho "define('FS_METHOD', 'direct'); define('TYPECHO_REDIS_HOST', 'redis'); define('TYPECHO_REDIS_PORT', '6379');" >> /home/web/html/web2/typecho/typecho-config-sample.php四、配置Caddyfile，以kjlion.com为例nano /home/web/caddy/Caddyfile{ frankenphp order mercure after encode order vulcain after reverse_proxy order php_server before file_server order php before file_server } kjlion.com { root * public/web1/wordpress encode zstd gzip php_server }五、启动环境wget -O /home/web/docker-compose.yml https://raw.githubusercontent.com/kejilion/docker/main/docker-compose-frankenphp.yml nano /home/web/docker-compose.yml cd /home/web && docker-compose up -d六、安装PHP扩展docker exec -it web install-php-extensions mysqli gd intl zip opcache docker exec -it web install-php-extensions exif imagick redis docker exec web sh -c 'echo "upload_max_filesize=50M \n post_max_size=50M" > /usr/local/etc/php/conf.d/uploads.ini' docker exec web sh -c 'echo "memory_limit=256M" > /usr/local/etc/php/conf.d/memory.ini' docker exec web sh -c 'echo "max_execution_time=1200" > /usr/local/etc/php/conf.d/max_execution_time.ini' docker exec web sh -c 'echo "max_input_time=600" > /usr/local/etc/php/conf.d/max_input_time.ini'七、创建数据库docker exec -it mysql mysql -u root -p CREATE DATABASE web1; GRANT ALL PRIVILEGES ON web1.* TO 'kejilion'@'%';八、重启环境cd /home/web && docker-compose restart

Caddy新一代轻量web服务器 配置简单 自动HTTPS 反向代理建站 Caddy新一代轻量web服务器 配置简单 自动HTTPS 反向代理建站Caddy 2是一款功能强大、企业级、开源 Web 服务器，具有用 Go 编写的自动 HTTPS。本文转自： 科技lion 一、docker一键安装curl -fsSL https://get.docker.com | sh && ln -s /usr/libexec/docker/cli-plugins/docker-compose /usr/local/bin二、创建Caddyfile和index.htmlmkdir -p /home/web/{caddy,html} touch /home/web/caddy/Caddyfile touch /home/web/html/index.html三、配置index.htmlhttps://github.com/kejilion/Website_source_code/blob/main/index.htmlnano /home/web/html/index.html四、配置Caddyfilenano /home/web/caddy/Caddyfile五、配置IP访问的静态页面【因上传软件原因， 可能出现乱码用不了 ，如安装后不起作用， 可把Caddyfile文件下载到本地编辑后再上传 】http:// { root * /usr/share/caddy encode gzip file_server }配置带域名的静态页面，下面都以“kjlion.com”为例kjlion.com { root * /usr/share/caddy encode gzip file_server }配置带域名的反向代理wp.kjlion.com { reverse_proxy 127.0.0.1:8080 encode gzip }配置带域名的重定向b.kjlion.com { redir https://baidu.com{uri} }配置带域名的php动态站点wp.kjlion.com { root * /usr/share/caddy/wordpress encode gzip php_fastcgi php:9000 file_server }六、部署caddydocker run -d --name caddy -p 80:80 -p 443:443 -p 443:443/udp -v /home/web/caddy/:/etc/caddy/ -v /home/web/html/:/usr/share/caddy/ --restart=always caddy:latest七、重启caddydocker restart caddy

linux删除文件夹命令使用方法 linux删除文件夹命令使用方法 在Linux中，删除目录中的文件夹和文件的方法其实很简单，使用rm -rf命令即可。一、删除文件夹实例：rm -rf /var/log/httpd删除/var/log/httpd目录以及其下所有文件、文件夹二、删除文件实例：rm -f /var/log/httpd/access.log这个将会强制删除/var/log/httpd/access.log这个文件注意：在linux中是没有设置回收站的，因此在使用rm命令的时候一定要小心些，删除之后的文件是无法恢复的。
