MacOS下的openresty编译过程

Ricky — Mon, 30 Oct 2023 22:56:49 +0800

其实还是比较简单的，毕竟homebrew已经很方便的安装了依赖，还是记录一下

基本依赖

我本地的brew是更新过了的，从github下载的最新release

brew update                            
brew install pcre openssl

configure

Linux:

./configure \                          
   --with-cc-opt="-I/usr/local/opt/openssl/include/ -I/usr/local/opt/pcre/include/" \
   --with-ld-opt="-L/usr/local/opt/openssl/lib/ -L/usr/local/opt/pcre/lib/" \
   -j8

MacOS:

./configure \                     
   --with-cc-opt="-I/opt/homebrew/include/openssl/ -I/opt/homebrew/include/" \
   --with-ld-opt="-L/opt/homebrew/lib/" \
   -j8

这里的路径是我自己找的，brew应该都一样，但是看到别的文章和我的不一样，所以应该先检查include和lib的路径

brotli

Brotli比我当年编译的简单多了:

git clone https://github.com/google/ngx_brotli.git`
cd ngx_brotli/deps/brotli
git clone https://github.com/google/brotli.git
cd ..
./configure \                      
   --with-cc-opt="-I/opt/homebrew/include/openssl/ -I/opt/homebrew/include/" \
   --with-ld-opt="-L/opt/homebrew/lib/ --add-module=/路径/ngx_brotli" \
   -j8

然后make -j8 && make install 就到了/usr/local/openresty下了

Nginx二级域名自动解析&伪静态&默认首页

Ricky — Sun, 03 Oct 2021 22:32:00 +0800

网站的目录结构为：

# tree /home/wwwroot/application.pub
/home/wwwroot/application.pub
├── ai
│   └── index.html
└── file
    └── index.html

/home/wwwroot/application.pub为nginx的安装目录下默认的存放源代码的路径。
ai为博客程序源代码路径
file为附件路径
把相应程序放入上面的路径通过
http://ai.application.pub 访问博客
http://file.application.pub 访问附件
其它二级域名类推。

方法一：

server {
listen 80;
server_name ~^(?.+).application.pub$;
access_log /data/wwwlogs/application.pub_nginx.log combined;
index index.html index.htm index.php;
root /home/wwwroot/application.pub/$subdomain/;
...
}

方法二：

server {
listen 80;
server_name *.application.pub;
access_log /home/wwwlogs/application.pub.log combined;
index index.html index.htm index.php;

if ($host ~* ^([^\.]+)\.([^\.]+\.[^\.]+)$) {
    set $subdomain $1;
    set $domain $2;
}

location / {
    root /home/wwwroot/application.pub/$subdomain/;
    index index.php $subdomain.html index.htm;
}

...
}

Nginx /var/run/nginx.pid 问题：nginx: [error] invalid PID number

Ricky — Wed, 07 Jul 2021 17:39:41 +0800

根据检查，除了网上说的没有带上-c以外，
还有一个情况，是/lib/service里面的nginx.service版本过旧导致的。
reload=nginx -s reload即可。

Nginx代理proxy pass配置去除前缀

Ricky — Tue, 29 Jun 2021 16:45:00 +0800

使用Nginx做代理的时候，可以简单的直接把请求原封不动的转发给下一个服务。

比如，访问abc.com/appv2/a/b.html, 要求转发到localhost:8088/appv2/a/b.html

简单配置如下：

upstream one {
  server localhost:8088 weight=5;
}

server {
    listen              80;
    server_name         abc.com;
    access_log  "pipe:rollback /data/log/nginx/access.log interval=1d baknum=7 maxsize=1G"  main;

    location / {
        proxy_set_header Host $host;
        proxy_set_header  X-Real-IP        $remote_addr;
        proxy_set_header  X-Forwarded-For  $proxy_add_x_forwarded_for;
        proxy_set_header X-NginX-Proxy true;

        proxy_pass http://one;
    }

}

即，设置proxy_pass即可。请求只会替换域名。

但很多时候，我们需要根据url的前缀转发到不同的服务。

比如

abc.com/user/profile.html转发到用户服务localhost:8089/profile.html

abc.com/order/details.html转发到订单服务 localhost:8090/details.html

即，url的前缀对下游的服务是不需要的，除非下游服务添加context-path, 但很多时候我们并不喜欢加这个。如果Nginx转发的时候，把这个前缀去掉就好了。

一个种方案是proxy_pass后面加根路径/.

server {
    listen              80;
    server_name         abc.com;
    access_log  "pipe:rollback /data/log/nginx/access.log interval=1d baknum=7 maxsize=1G"  main;

    location ^~/user/ {
        proxy_set_header Host $host;
        proxy_set_header  X-Real-IP        $remote_addr;
        proxy_set_header  X-Forwarded-For  $proxy_add_x_forwarded_for;
        proxy_set_header X-NginX-Proxy true;

        proxy_pass http://user/;
    }

    location ^~/order/ {
        proxy_set_header Host $host;
        proxy_set_header  X-Real-IP        $remote_addr;
        proxy_set_header  X-Forwarded-For  $proxy_add_x_forwarded_for;
        proxy_set_header X-NginX-Proxy true;

        proxy_pass http://order/;
    }

}

^~/user/表示匹配前缀是user的请求，proxy_pass的结尾有/，则会把/user/*后面的路径直接拼接到后面，即移除user.

另一种方案是使用rewrite

upstream user {
  server localhost:8089 weight=5;
}
upstream order {
  server localhost:8090 weight=5;
}


server {
    listen              80;
    server_name         abc.com;
    access_log  "pipe:rollback /data/log/nginx/access.log interval=1d baknum=7 maxsize=1G"  main;

    location ^~/user/ {
        proxy_set_header Host $host;
        proxy_set_header  X-Real-IP        $remote_addr;
        proxy_set_header  X-Forwarded-For  $proxy_add_x_forwarded_for;
        proxy_set_header X-NginX-Proxy true;

        rewrite ^/user/(.*)$ /$1 break;
        proxy_pass http://user;
    }

    location ^~/order/ {
        proxy_set_header Host $host;
        proxy_set_header  X-Real-IP        $remote_addr;
        proxy_set_header  X-Forwarded-For  $proxy_add_x_forwarded_for;
        proxy_set_header X-NginX-Proxy true;

        rewrite ^/order/(.*)$ /$1 break;
        proxy_pass http://order;
    }

}

注意到proxy_pass结尾没有/， rewrite重写了url。
