Mac下安装nginx,我使用的是Homebrew,Homebrew安装好的情况下。

1.先安装pcre.

ksnowlv@ksnowlvdeMacBook-Pro~/Movies/PHP$brew install pcre
ksnowlv@ksnowlvdeMacBook-Pro~/Movies/PHP$brew install pcre
==> Downloading https://downloads.sf.net/project/machomebrew/Bottles/pcre-8.35.mavericks.bottle.tar.gz
Already downloaded: /Library/Caches/Homebrew/pcre-8.35.mavericks.bottle.tar.gz
==> Pouring pcre-8.35.mavericks.bottle.tar.gz
#忽略该错误是要付出代价的，请看后面!!!!!
Error: The `brew link` step did not complete successfully
The formula built, but is not symlinked into /usr/local
Could not symlink share/man/man1/pcre-config.1
Target /usr/local/share/man/man1/pcre-config.1
already exists. You may want to remove it:
  rm /usr/local/share/man/man1/pcre-config.1
#解决方法之一，注意!!!
To force the link and overwrite all conflicting files:
  brew link --overwrite pcre

To list all files that would be deleted:
  brew link --overwrite --dry-run pcre

Possible conflicting files are:

静待pcre安装完即可。

2.安装nginx.

ksnowlv@ksnowlvdeMacBook-Pro~/Movies/PHP$brew install nginx
==> Downloading https://downloads.sf.net/project/machomebrew/    Bottles/nginx-1.6.1.mavericks.bottle.tar.gz

静待nginx安装完成即可。

如果安装出错，例如出现

 Error: You must `brew link pcre' before nginx can be installed   

参考链接:http://ksnowlv.gitcafe.com/blog/2014/08/18/you-must-brew-link-pcre-before-nginx-can-be-installed/ 解决办法。

如果解决上述错误会怎么样呢？nginx环境安装不成功呗。

在启动nginx时，http://localhost:8080/，页面一直显示404。

3.启动nginx。

ksnowlv@ksnowlvdeMacBook-Pro~/Movies/PHP$sudo nginx
Password:

输入正确密码后,在浏览器中打开http://localhost:8080/,即可看到nginx欢迎页面

可以使用sudo nginx -s stop关闭nginx服务。

ksnowlv@ksnowlvdeMacBook-Pro~/Movies/PHP$sudo nginx -s stop

4.查看nginx版本信息和help

ksnowlv@ksnowlvdeMacBook-Pro~/Movies/PHP$nginx -v
nginx version: nginx/1.6.1

ksnowlv@ksnowlvdeMacBook-Pro~/Movies/PHP$nginx -h
nginx version: nginx/1.6.1
Usage: nginx [-?hvVtq] [-s signal] [-c filename] [-p prefix] [-g directives]

Options:
  -?,-h         : this help
  -v            : show version and exit
  -V            : show version and configure options then exit
  -t            : test configuration and exit
  -q            : suppress non-error messages during configuration testing
  -s signal     : send signal to a master process: stop, quit, reopen, reload
  -p prefix     : set prefix path (default: /usr/local/Cellar/nginx/1.6.1/)
  -c filename   : set configuration file (default: /usr/local/etc/nginx/nginx.conf)
  -g directives : set global directives out of configuration file

总结:今天尝试把pcre,nginx在Mac上卸载一遍,重新安装时,才发现当时忽略

Error: You must `brew link pcre' before nginx can be installed

是多大的灾难,一直是以为配置不对,前前后后检查配置文件…
