CentOS6.9 安装与配置 Nginx 1.14.0

参考：http://www.runoob.com/linux/nginx-install-setup.html

https://blog.csdn.net/zhiyuan_2007/article/details/71238216

http://nginx.org/en/docs/stream/ngx_stream_core_module.html

首先下载安装包和依赖包：

https://jaist.dl.sourceforge.net/project/pcre/pcre/8.42/pcre-8.42.tar.gz

http://nginx.org/download/nginx-1.14.0.tar.gz

安装其他需要的依赖包：

sudo yum -y install make zlib zlib-devel gcc-c++ libtool  openssl openssl-devel

解压并安装pcre：

tar -zxf pcre-8.42.tar.gz
cd pcre-8.42
./configure --prefix=/usr/local/pcre
make
sudo make install

[taiji@localhost pcre-8.42]$ sudo /usr/local/pcre/bin/pcre-config --version
8.42
[taiji@localhost pcre-8.42]$ 

解压并安装nginx：

tar -zxf nginx-1.14.0.tar.gz
cd nginx-1.14.0
./configure --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module --with-pcre=../pcre-8.42 --with-stream
make
sudo make install

配置防火墙：

sudo vim /etc/sysconfig/iptables

增加规则：

-A INPUT -p tcp -m state --state NEW -m tcp --dport 80 -j ACCEPT

重起iptables ：

sudo service iptables restart

就可以访问nginx了

Nginx 其他命令

以下包含了 Nginx 常用的几个命令：

/usr/local/webserver/nginx/sbin/nginx -s reload            # 重新载入配置文件
/usr/local/webserver/nginx/sbin/nginx -s reopen            # 重启 Nginx
/usr/local/webserver/nginx/sbin/nginx -s stop              # 停止 Nginx

附上配置文件：

#user  nobody;
worker_processes  1;

error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

pid        logs/nginx.pid;

    worker_connections  1024;
}

                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  logs/access.log  main;

        location / {

            index  index.html index.htm;
        }

        #error_page  404              /404.html;
        # redirect server error pages to the static page /50x.html
        #

        location = /50x.html {
