手动安装caddy2 debian

在 上张贴 由 Hi:您好发表回复

更新系统

apt-get update && apt-get upgrade -y

基础工具下载安装

apt update && apt -y install build-essential libnss3 libpcre3 libpcre3-dev zlib1g-dev git dbus manpages-dev aptitude g++ wget curl unzip gcc

校准时间

ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime && date -R

下载安装GO编程语言

wget https://go.dev/dl/go1.19.3.linux-amd64.tar.gz

解压至/usr/local/

tar -C /usr/local -xzf go1.19.3.linux-amd64.tar.gz

在/etc/profile中添加 Go 环境变量:

echo "export PATH=$PATH:/usr/local/go/bin" >> /etc/profile

使修改的配置文件立即生效

source /etc/profile

编译安装 Caddy

go install github.com/caddyserver/xcaddy/cmd/xcaddy@latest

编译安装(下面的插件感觉不需要的可以去掉)

~/go/bin/xcaddy build \
    --with github.com/caddyserver/forwardproxy@caddy2=github.com/klzgrad/forwardproxy@naive \
    --with github.com/abiosoft/caddy-exec \
    --with github.com/caddy-dns/cloudflare \
    --with github.com/mholt/caddy-l4 \
    --with github.com/greenpau/caddy-trace \
    --with github.com/hairyhenderson/caddy-teapot-module \
    --with github.com/kirsch33/realip \
    --with github.com/porech/caddy-maxmind-geolocation \
    --with github.com/mholt/caddy-webdav


删除编译后的文件夹

rm -rf go go1.19.3.linux-amd64.tar.gz

创建文件夹

mkdir -p /usr/share/caddy/ /etc/caddy/ /etc/ssl/caddy/ /var/log/caddy/

创建文件

touch /var/log/caddy/access.log /etc/caddy/Caddyfile
mv ./caddy /usr/bin/

安装MariaDB php：

apt install php-fpm php-mysql mariadb-server

安装php插件：

apt install php-curl php-gd php-imagick php-intl php-mbstring php-zip php-dom

MariaDB安全加固：
会设置密码，界面1直接回车，剩的都选Y：

mysql_secure_installation

root登录：

mysql -u root -p

查看当前的数据库：

show databases;

创建数据库非root用户名密码：
**wordpress 数据库名， name 用户名，password 密码 **
create database wordpress; create user name@localhost identified by ‘password’;
授予权限：

grant all privileges on wordpress.* to name@localhost; flush privileges;

退出：

exit

博客下载地址 https://typecho.org/ 解压放在/usr/share/caddy/文件夹下，

用的非root账户要给html文件夹赋给权限：

chown -R www-data:www-data caddy

开启BBR加速（可跳过）

echo "net.core.default_qdisc=fq" >> /etc/sysctl.conf && echo "net.ipv4.tcp_congestion_control=bbr" >> /etc/sysctl.conf && sysctl -p && lsmod | grep bbr

====出现缓冲过小错误时====

建议通过运行来增加最大缓冲区大小：

sysctl -w net.core.rmem_max=2500000

重载systemctl服务

systemctl daemon-reload

开启caddy2

systemctl start caddy && systemctl status caddy

设置为开机自动启动

systemctl enable caddy

每次修改后都要执行一次重启

systemctl restart caddy

停止caddy

service caddy stop

开启php7.4-fpm：

systemctl start php7.4-fpm

开启状态：

systemctl status php7.4-fpm

开机自动启动：

systemctl enable php7.4-fpm

重新启动：

systemctl restart php7.4-fpm

开启mysql：

systemctl start mariadb.service

开启状态：

systemctl status mariadb.service

开机自动启动：

systemctl enable mariadb.service

重新启动：

systemctl restart mariadb.service

从 Caddyfile 生成 JSON 配置

./caddy adapt --config ./Caddyfile --pretty

直接内容输出到文本

./caddy adapt --config ./Caddyfile > ./config.json

验证 Caddyfile 有效性

./caddy adapt --config ./Caddyfile --validate
