CentOS 7 搭建 WebDav 服务器

大部分参考了这篇文章：https://blog.acesheep.com/index.php/archives/834/
本文对其中的关键点进行记录，并调整了部分配置，解决mac os finder连接上之后，无法新建和修改文件的问题

1、安装编译环境

yum install epel-release expat-devel httpd-tools unzipwget centos-release-scl git libxslt-devel libxml2-devel -y
yum install devtoolset-9-gcc* -y
yum groupinstall "Development tools"-y
yum -yinstall ghostscript

增加了ghostscript，后面zlib会依赖到

2、创建非特权账户

groupadd nginx
useradd-g nginx -c"nginx user"-d /var/cache/nginx -s /sbin/nologin nginx

这里和原文的区别是第一条命令移除了-g 994参数，第二条命令移除了-g 994 -u 996参数，换成了-g nginx，这么做的原因是因为：-g和-u是指定用户id和组id为994和996，但是实际情况下这两个id可能被占用了，导致创建失败。

3、下载源代码

# 创建目录mkdir nginx-webdav
cd nginx-webdav

# 下载nginx 1.20.2wgetwget https://nginx.org/download/nginx-1.20.2.tar.gz

# download pcre 8.45 / zlib 1.2.11 / openssl 1.1.1m dependencywget https://sourceforge.net/projects/pcre/files/pcre/8.45/pcre-8.45.tar.gz
wget http://zlib.net/zlib-1.2.11.tar.gz
git clone https://github.com/madler/zlib.git &&cd$(basename https://github.com/madler/zlib.git .git)&&git checkout v1.2.11 &&cd..&&mv zlib zlib-1.2.11
wget http://www.openssl.org/source/openssl-1.1.1m.tar.gz

# download nginx-dav-ext-module git.r112.f5e3088git clone https://github.com/arut/nginx-dav-ext-module.git

# download headers-more-nginx-module git.r259.a4a0686git clone https://github.com/openresty/headers-more-nginx-module.git

# Extract source filetar-zxf pcre-8.45.tar.gz
tar-zxf openssl-1.1.1m.tar.gz
tar-zxf nginx-1.20.2.tar.gz

调整了下zlib的下载方式，因为1.2.11版本在官网已经下载不到了。

文件列表

➜  nginx-webdav tree -L 1  
.

├── pcre-8.45.tar.gz
└── zlib-1.2.11

7 directories, 3 files

4、修改源码

sed-i's/NGX_HTTP_AUTOINDEX_PREALLOCATE  50/NGX_HTTP_AUTOINDEX_PREALLOCATE  110/g' nginx-1.20.2/src/http/modules/ngx_http_autoindex_module.c

5、编译

cd nginx-1.20.2

scl enable devtoolset-9 "./configure --prefix=/etc/nginx --sbin-path=/usr/sbin/nginx --modules-path=/usr/lib64/nginx/modules --conf-path=/etc/nginx/nginx.conf --error-log-path=/var/log/nginx/error.log --http-log-path=/var/log/nginx/access.log --pid-path=/var/run/nginx.pid --lock-path=/var/run/nginx.lock --http-client-body-temp-path=/var/cache/nginx/client_temp --http-proxy-temp-path=/var/cache/nginx/proxy_temp --http-fastcgi-temp-path=/var/cache/nginx/fastcgi_temp --http-uwsgi-temp-path=/var/cache/nginx/uwsgi_temp --http-scgi-temp-path=/var/cache/nginx/scgi_temp --user=nginx --group=nginx --with-zlib=../zlib-1.2.11 --with-zlib-opt='-g -Ofast -fPIC -m64 -march=native -fstack-protector-strong -D_FORTIFY_SOURCE=2' --with-pcre=../pcre-8.45 --with-pcre-opt='-g -Ofast -fPIC -m64 -march=native -fstack-protector-strong -D_FORTIFY_SOURCE=2' --with-pcre-jit --with-compat --with-file-aio --with-threads --with-http_addition_module --with-http_auth_request_module --with-http_dav_module --add-module=../nginx-dav-ext-module --add-module=../headers-more-nginx-module --with-openssl=../openssl-1.1.1m --with-http_xslt_module --with-http_flv_module --with-http_gunzip_module --with-http_gzip_static_module --with-http_mp4_module --with-http_random_index_module --with-http_realip_module --with-http_secure_link_module --with-http_slice_module --with-http_ssl_module --with-http_stub_status_module --with-http_sub_module --with-http_v2_module --with-mail --with-mail_ssl_module --with-stream --with-stream_realip_module --with-stream_ssl_module --with-stream_ssl_preread_module --with-cc-opt='-O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches -m64 -mtune=generic -fPIC' --with-ld-opt='-Wl,-z,relro -Wl,-z,now -pie'"

scl enable devtoolset-9 "make -j"

./objs/nginx -Vmakeinstall

安装完成后，可以使用

nginx -V

检查安装的nginx版本

6、创建系统服务

cat<<'EOF'> /usr/lib/systemd/system/nginx.service
[Unit]
Description=nginx - high performance web server
Documentation=http://nginx.org/en/docs/
After=network-online.target remote-fs.target nss-lookup.target
Wants=network-online.target

[Service]
Type=forking
PIDFile=/var/run/nginx.pid
ExecStart=/usr/sbin/nginx -c /etc/nginx/nginx.conf
ExecReload=/bin/sh -c "/bin/kill -s HUP $(/bin/cat /var/run/nginx.pid)"
ExecStop=/bin/sh -c "/bin/kill -s TERM $(/bin/cat /var/run/nginx.pid)"

[Install]
WantedBy=multi-user.target
EOF

systemctl enable nginx
systemctl start nginx

7、配置nginx

# 创建配置目录mkdir /etc/nginx/conf.d

修改nginx配置：

vim /etc/nginx/nginx.conf

这里与原文的区别是，增加了dav_ext_lock_zone zone=foo:10m;配置。
用于解决mac finder无法新增和修改文件的问题

user nginx;

worker_processes auto;

error_log /var/log/nginx/error.log warn;
pid /var/run/nginx.pid;# Specifies the value for maximum file descriptors that can be opened by this process.
worker_rlimit_nofile 51200;# PCRE JIT can speed up processing of regular expressions significantly.
pcre_jit on;

events {
    use epoll;
    worker_connections 51200;
    multi_accept on;}

http {
    log_format main '$remote_addr - $remote_user [$time_local] "$request" ''$status $body_bytes_sent "$http_referer" ''"$http_user_agent" "$http_x_forwarded_for"';

    include /etc/nginx/mime.types;
    default_type application/octet-stream;

    server_names_hash_bucket_size 128;
    client_header_buffer_size 32k;
    large_client_header_buffers 4 32k;
    client_max_body_size 50m;

    charset utf-8;
    sendfile on;
    server_tokens off;
    tcp_nodelay on;
    tcp_nopush on;
    real_ip_header X-Forwarded-For;
    types_hash_max_size 2048;
    keepalive_timeout 60;
    access_log /var/log/nginx/access.log main;

    fastcgi_connect_timeout 300;
    fastcgi_send_timeout 300;
    fastcgi_read_timeout 300;
    fastcgi_buffer_size 64k;
    fastcgi_buffers 4 64k;
    fastcgi_busy_buffers_size 128k;
    fastcgi_temp_file_write_size 256k;gzip on;
    gzip_min_length 1k;
    gzip_buffers 4 16k;
    gzip_http_version 1.1;
    gzip_comp_level 2;
    gzip_types text/plain text/css application/json application/javascript application/x-javascript text/xml application/xml application/xml+rss text/javascript;
    gzip_vary on;
    gzip_proxied expired no-cache no-store private auth;
    gzip_disable "MSIE [1-6]\.";
    
    dav_ext_lock_zone zone=foo:10m;

    server {
        listen 80 default_server;
        listen [::]:80 default_server;if($host ~ "\d+\.\d+\.\d+\.\d+"){return404;}return301 https://$host$request_uri;}

    include /etc/nginx/conf.d/*.conf;}

修改文件

vim /etc/nginx/conf.d/webdav.conf

这里与原文的区别是，增加了dav_ext_lock zone=foo;配置，并调整了dav_ext_methods配置为PROPFIND OPTIONS LOCK UNLOCK 这四个参数，原文只有前两个，导致mac无法修改文件。这些配置也是为了解决mac无法新增和修改文件的问题。
注意修改下ssl的证书和key，替换成自己的

server {
    listen 443 ssl http2;
    listen [::]:443 ssl http2;
    server_name example.com;

    ssl_certificate "/home/SSL/example.com.crt";
    ssl_certificate_key "/home/SSL/example.com.key";
    ssl_session_cache shared:SSL:20m;
    ssl_session_timeout 30m;
    ssl_session_tickets off;
    ssl_protocols TLSv1.2 TLSv1.3;
    ssl_ciphers TLS13-CHACHA20-POLY1305-SHA256:TLS13-AES-256-GCM-SHA384:TLS13-AES-128-GCM-SHA256:EECDH+CHACHA20:EECDH+AESGCM:EECDH+AES;
    ssl_prefer_server_ciphers on;

    access_log /var/log/nginx/access-example.com.log main;
    error_log /var/log/nginx/error-example.com.log error;

    location / {# 设置webdav目录，注意Nginx worker用户对该目录需有读/写/执行权限
        root /home/nginx;

        auth_basic "closed site";
        auth_basic_user_file /etc/nginx/conf.d/webdav.htpasswd;

        dav_methods PUT DELETE MKCOL COPY MOVE;
        dav_ext_methods PROPFIND OPTIONS LOCK UNLOCK;
        dav_ext_lock zone=foo;# 启用完整的创建目录支持
        create_full_put_path on;
        dav_access user:rw group:rw;

        autoindex on;
        autoindex_localtime on;
        autoindex_exact_size off;# 不限制文件大小
        client_max_body_size 0;# 为各种方法的URI后加上斜杠，解决各平台webdav客户端的兼容性问题set$dest$http_destination;if(-d $request_filename){
            rewrite ^(.*[^/])$ $1/;set$dest$dest/;}if($request_method ~ (MOVE|COPY)){
            more_set_input_headers 'Destination: $dest';}if($request_method ~ MKCOL){
            rewrite ^(.*[^/])$ $1/ break;}}# Mac挂载webdav后会自动写入很多文件，可以通过nginx配置屏蔽掉，保持webdav目录的干净
    location ~ \.(_.*|DS_Store|Spotlight-V100|TemporaryItems|Trashes|hidden|localized)$ {
        access_log off;
        error_log off;if($request_method= PUT){return403;}return404;}

    location ~ \.metadata_never_index$ {return200"Don't index this drive, Finder!";}}

创建完配置之后，执行下

nginx -s reload

重新加载下配置

8、配置账户

yum install httpd-tools -y# 其中nginx是用户名，可以自行修改htpasswd执行完之后，会要求输入密码。
htpasswd -c /etc/nginx/conf.d/webdav.htpasswd 'nginx'

9、创建目录添加权限

mkdir /home/nginx
chown nginx:nginx /home/nginx
chmod-R774 /home/nginx

此时应该就可以用finder进行连接了。
注意，如果域名没有备案，是连不上的，换成ip进行连接即可。
