一、安装

1、下载pcre-8.41.tar.gz包，下载路径：ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/

2、下载nginx，下载版本为nginx-1.12.1.tar.gz

3、解压上面下载的两个文件：
tar -zxvf pcre-8.41.tar.gz
tar -zxvf nginx-1.12.1.tar.gz

4、编译并安装pcre

进入刚才解压后的pcre-8.41目录下，

先编译：

./configure
安装：
make && make install
如果上面没有报错，并且使用命令可以查看到pcre版本，则表示已安装成功，查看版本命令：
pcre-config --version

5、编译安装nginx

进入刚才解压后的nginx-1.12.1目录下，

先编译：

./configure --with-http_stub_status_module --prefix=/usr/local/nginx-1.12.1

安装：
make && make install
要是上面，没有报错，并且在/usr/local/目录下生成了nginx-1.12.1文件夹，则表示已经安装成功

注意：pcre若是在编译时，指定了路径，如使用：
        ./configure --prefix=/usr/local/pcre-8.4
        则编译nginx时，需要添加pcre-8.4包的路径，如下：
        ./configure --with-http_stub_status_module --prefix=/usr/local/nginx-1.12.1 --with-pcre=/usr/local/pcre-8.4

其他部分和上面一样。

二、配置

    #    }
    #}

    #    location / {
    #        root   html;
    #        index  index.html index.htm;
    #    }
    #}

}

三、启动

修改完配置文件后，启动nginx，使用命令：

/usr/local/nginx-1.12.1/sbin/nginx

启动报如下错误：
