一、编译安装模块
如果是原有包中就有的模块，编译时，
./configure --with-xxx 就可以，
如果是第三方模块，可使用 --add-module，
如果有多个模块的话,只需要多次使用-add-module指令即可.
二、下载源码包image_fliter和echo模块
nginx源码下载
http://nginx.org/en/download.html
echo模块下载
https://github.com/openresty/echo-nginx-module/tags
解压
gzip -d xxx.tar.gz
tar -zvxf xxx.tar xxx
三.编译
1.安装依赖：
brew install pcre
brew install gd #image filter依赖gd
brew link --force openssl #避免编译openssl时报错
2.cd nginx源码目录
./configure xxx
--prefix 设置编译目录
3.查看原有nginx编译参数
4.添加编译module
./configure \
--with-http_image_filter_module \
--with-debug \
--add-module=/Users/fanfan/web/software/echo-nginx-module-0.61 \
原有编译参数，
(注意修改版本目录)
./configure \
--prefix=/usr/local/Cellar/nginx/1.12.2 \
--with-http_ssl_module \
--with-pcre \
--sbin-path=/usr/local/Cellar/nginx/1.12.2/bin/nginx \
--with-cc-opt='-I/usr/local/opt/pcre/include -I/usr/local/opt/openssl@1.1/include' \
--with-ld-opt='-L/usr/local/opt/pcre/lib -L/usr/local/opt/openssl@1.1/lib' \
--conf-path=/usr/local/etc/nginx/nginx.conf \
--pid-path=/usr/local/var/run/nginx.pid \
--lock-path=/usr/local/var/run/nginx.lock \
--http-client-body-temp-path=/usr/local/var/run/nginx/client_body_temp \
--http-proxy-temp-path=/usr/local/var/run/nginx/proxy_temp \
--http-fastcgi-temp-path=/usr/local/var/run/nginx/fastcgi_temp \
--http-uwsgi-temp-path=/usr/local/var/run/nginx/uwsgi_temp \
--http-scgi-temp-path=/usr/local/var/run/nginx/scgi_temp \
--http-log-path=/usr/local/var/log/nginx/access.log \
--error-log-path=/usr/local/var/log/nginx/error.log \
--with-http_gzip_static_module --with-http_v2_module \
--with-http_image_filter_module \
--with-debug \
--add-module=/Users/fanfan/web/software/echo-nginx-module-0.61
------------------------------------------------------------------------------
./configure --prefix=/usr/local/nginx-1.4.1 --with-http_stub_status_module \
--with-http_realip_module --with-http_image_filter_module --with-debug
5.make
四.安装
1.如果之前未安装nginx
2.如果之前通过brew安装过nginx
/usr/local/bin/nginx /usr/local/Cellar/nginx/xxx/bin/nginx
/usr/local/opt/nginx /usr/local/Cellar/nginx/xxx
修改软连接，直接指向新的nginx
3.替换编译文件的方式
这种方式，只是替换了bin文件，目录还是原来的
#备份原来的binary
cp /usr/local/opt/nginx/bin/nginx /usr/local/opt/nginx/bin/nginx.bak
#先cd到nginx源码目录
sudo cp objs/nginx /usr/local/opt/nginx/bin/nginx
rm /usr/local/bin/nginx
ln -s /usr/local/opt/nginx/bin/nginx /usr/local/bin/nginx
4.建立版本目录方式
$ cp -r /usr/local/Cellar/nginx/1.8.0 /usr/local/Cellar/nginx/1.9.10
#先cd到nginx源码目录
$ sudo cp objs/nginx /usr/local/Cellar/nginx/1.9.10/bin
#更新/usr/local/opt/nginx
$ rm /usr/local/opt/nginx
$ ln -s /usr/local/Cellar/nginx/xxx /usr/local/opt/nginx
#更新/usr/local/bin/nginx
$ rm /usr/local/bin/nginx
$ ln -s /usr/local/opt/nginx/bin/nginx /usr/local/bin/nginx
5.编辑/Library/LaunchDaemons/homebrew.mxcl.nginx.plist
好像也不用编辑
launchctl load -F /Library/LaunchDaemons/homebrew.mxcl.nginx.plist
五.验证nginx
nginx -V / nginx -v
yld: Library not loaded: /usr/local/opt/jpeg/lib/libjpeg.8.dylib
nginx版本依赖 jpeg 8d的版本，而brew install jpeg 的时候，安装的是新版9b
可转换成上一版本即可
brew switch jpeg 8d
或者 因为其他版本安装出现此问题，可重新安装，rebuild source，
这样使用的就是最新版本的依赖
brew cleanup //更新cellar
brew reinstall php71 --build-from-source
https://stackoverflow.com/questions/32703296/dyld-library-not-loaded-usr-local-lib-libjpeg-8-dylib-homebrew-php
六.重启nginx
nginx -t //验证配置文件是否正确
有可能会有权限问题，启动时，以root用户启动即可
sudo brew services restart nginx
