[系统运维]macos 安装nginx

网上大部分文章都是yum（Linux）或者用brew安装。本人机器macos 10.15.2，刚开始使用brew安装不成功，于是选择离线安装。安装Nginx需要用到pcre和openssl，需要提前准备这两个文件。

1.安装openssl

到官网下载安装包，解压后切换到openssl的目录，执行以下命令：

./config --prefix=/usr/local/openssl

看到以下信息表示配置成功。

**********************************************************************
***                                                                ***
***   OpenSSL has been successfully configured                     ***
***                                                                ***
***   If you encounter a problem while building, please open an    ***
***   issue on GitHub <https://github.com/openssl/openssl/issues>  ***
***   and include the output from the following command:           ***
***                                                                ***
***       perl configdata.pm --dump                                ***
***                                                                ***
***   (If you are new to OpenSSL, you might want to consult the    ***
***   'Troubleshooting' section in the INSTALL file first)         ***
***                                                                ***
**********************************************************************

然后执行以下命令：

make && make install

接着是漫长的等待。如果提示权限：

Cannot create directory /usr/local/openssl: Permission denied

执行以下命令：

sudo chown -R $(whoami) /usr/local/

2.安装pcre

仍然采用离线的方式安装，到下面的地址下载安装包：

ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.36.zip

解压后，切换到解压后的目录输入以下命令：

./configure --prefix=/usr/local/pcre --enable-utf8 --enable-unicode-properties

3.安装nginx

到nginx官网下载安装包解压，并切换到安装目录，执行以下命令：

./configure --prefix=/usr/local/nginx

然后屏幕呼呼啦啦一堆代码，最后几行如下：

/configure: error: the HTTP rewrite module requires the PCRE library.
You can either disable the module by using --without-http_rewrite_module
option, or install the PCRE library into the system, or build the PCRE library
statically from the source with nginx by using --with-pcre=<path> option.

啊哈，出错了，提示缺少pcre库，刚才明明已经安装了，说明姿势不对，换个姿势重来。上面的命令不完整，需要指定pcre的目录和openssl的目录，但是这个目录不是安装后的目录，而是刚开始解压的后的位置。执行以下命令（注意with）：

./configure --prefix=/usr/local/nginx --with-pcre=/Users/imac/software/pcre-8.36 --with-openssl=/Users/imac/software/openssl-1.1.1n

出现以下内容说明成功

Configuration summary
  + using PCRE library: /Users/imac/software/pcre-8.36
  + using OpenSSL library: /Users/imac/software/openssl-1.1.1n
  + using system zlib library

  nginx path prefix: "/usr/local/nginx"
  nginx binary file: "/usr/local/nginx/sbin/nginx"
  nginx modules path: "/usr/local/nginx/modules"
  nginx configuration prefix: "/usr/local/nginx/conf"
  nginx configuration file: "/usr/local/nginx/conf/nginx.conf"
  nginx pid file: "/usr/local/nginx/logs/nginx.pid"
  nginx error log file: "/usr/local/nginx/logs/error.log"
  nginx http access log file: "/usr/local/nginx/logs/access.log"
  nginx http client request body temporary files: "client_body_temp"
  nginx http proxy temporary files: "proxy_temp"
  nginx http fastcgi temporary files: "fastcgi_temp"
  nginx http uwsgi temporary files: "uwsgi_temp"
  nginx http scgi temporary files: "scgi_temp"

执行以下命令：

make && make install

安装成功以后会在/usr/local下出现nginx目录

4、启动nginx

切换到/usr/local/nginx目录，执行以下命令

cd /usr/local/nginx

访问localhost,出现以下界面说明启动成功：

如果是用brew安装出现404，请切换源之后再安装：

brew install nginx

清华源最近好像有问题，请参考另一篇文章macos中brew切换到阿里源_Apple_羊先森的博客-CSDN博客macos中brew切换到阿里源https://blog.csdn.net/caicaimaomao/article/details/123662715
