学习笔记►OSX

在OSX上编译安装nginx

在OSX上，一般情况下，使用brew安装nginx，再链接一个plist到/Library/LaunchDaemons即可。但是有时候brew中的nginx缺少某些模块，比如上文提到的ngx_http_image_filter_module，这时就需要重新编译nginx。
更正：homebrew中提供nginx-full包，包含了常用的绝大多数模块。当然如果需要添加第三方模块还是需要手动编译。

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

编译

下面的示例中，添加以下几个模块：

  • http_image_filter_module
  • http_ssl_module
  • http_gzip_static_module
  • http_sub_module
    并且其他配置和homebrew的nginx大致相同（带版本号的路径除外）

    #cd到nginx源码目录
    $ ./configure --with-http_image_filter_module --with-http_ssl_module --with-http_gzip_static_module --with-http_sub_module \
    --prefix=/usr/local/Cellar/nginx/1.9.10 \
    --with-cc-opt="-I /usr/local/include" --with-ld-opt="-L /usr/local/lib" \
    --sbin-path=/usr/local/Cellar/nginx/1.9.10/bin/nginx \
    --conf-path=/usr/local/etc/nginx/nginx.conf \
    --pid-path=/usr/local/var/run/nginx.pid \
    --http-log-path=/usr/local/var/log/nginx/access.log \
    --error-log-path=/usr/local/var/log/nginx/error.log --with-pcre --with-ipv6 \
    --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
    $ make

其中，--with-cc-opt="-I /usr/local/include" --with-ld-opt="-L /usr/local/lib"可避免报Undefined symbols for architecture x86_64错误。/usr/local/Cellar/nginx/1.9.10这里的1.9.10替换为将要编译的nginx版本号。

安装

如果之前未安装过nginx，运行这条命令来安装：

1
$ make install

如果已使用brew安装nginx，可以通过替换文件的方式换成刚才编译的版本：

#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

现在，可以查看nginx版本：

1
$ nginx -V

强迫症患者可以像我这样在Cellar中建立一个新的版本目录：

$ cp -r /usr/local/Cellar/nginx/1.8.0 /usr/local/Cellar/nginx/1.9.10
#恢复1.8.0中的binary
$ rm /usr/local/Cellar/nginx/1.8.0/bin/nginx
$ mv /usr/local/Cellar/nginx/1.8.0/bin/nginx.bak /usr/local/Cellar/nginx/1.8.0/bin/nginx
#更新/usr/local/opt/nginx
$ rm /usr/local/opt/nginx
$ ln -s /usr/local/Cellar/nginx/1.9.10 /usr/local/opt/nginx

将nginx加入LaunchDaemons

编辑/Library/LaunchDaemons/homebrew.mxcl.nginx.plist内容如下：（brew的nginx自带的版本）

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
  <dict>
    <key>Label</key>
    <string>homebrew.mxcl.nginx</string>
    <key>RunAtLoad</key>
    <true/>
    <key>KeepAlive</key>
    <false/>
    <key>ProgramArguments</key>
    <array>
        <string>/usr/local/opt/nginx/bin/nginx</string>

        <string>daemon off;</string>
    </array>
    <key>WorkingDirectory</key>
    <string>/usr/local</string>

</plist>

然后：

1
$ launchctl load -F /Library/LaunchDaemons/homebrew.mxcl.nginx.plist
