Nginx安装和域名配置

Posted 2020-10-31 Just do it

一、安装必要的库

yum install gc gcc gcc-c++ pcre-devel zlib-devel openssl-devel

二、创建nginx用户和组

groupadd www
useradd -s /sbin/nologin -g www -M www    #创建一个用户,不允许登陆和不创主目录 

三、下载并解压nginx

wget http://nginx.org/download/nginx-1.12.0.tar.gz
tar -xzvf nginx-1.12.0
cd nginx-1.12.0

四、配置并编译安装

./configure --prefix=/usr/local/nginx --user=www --group=www --with-http_stub_status_module --with-http_ssl_module --with-http_realip_module --with-http_gzip_static_module --with-pcre

--with-http_stub_status_module：支持nginx状态查询
--with-http_ssl_module：支持https
--with-http_realip_module：在nginx访问日志中去除代理IP，显示客户的真实IP
--with-http_gzip_static_module：启用静态压缩
--with-pcre：为了支持rewrite重写功能，必须制定pcre

Configuration summary
  + using system PCRE library
  + using system OpenSSL library
  + 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"

出现如上信息表上configure成功，执行：

make && make install

五、启动、关闭、重启nginx

启动：直接执行以下命令,nginx就启动了,不需要改任何配置文件

# /usr/local/nginx/sbin/nginx

# curl -s http://localhost  #即可查看目录下的默认index.html页面

关闭：

查询nginx主进程号  ps -ef | grep nginx
从容停止   kill -QUIT 主进程号
快速停止   kill -TERM 主进程号
强制停止   kill -9 nginx
若nginx.conf配置了pid文件路径，如果没有，则在logs目录下
kill -信号类型 ‘/usr/local/nginx/logs/nginx.pid‘

更改配置重启nginx：

kill -HUP 主进程号或进程号文件路径
#或者
/usr/local/nginx/sbin/nginx -s reload

注意，修改了配置文件后最好先检查一下修改过的配置文件是否正 确，以免重启后Nginx出现错误影响服务器稳定运行。判断Nginx配置是否正确命令如下：

nginx -t -c /usr/local/nginx/conf/nginx.conf
#或者
/usr/local/nginx/sbin/nginx -t

六、域名配置

在"/usr/local/nginx/conf"目录下新建"vhost"目录，所有的站点配置文件放在vhost中

"/usr/local/nginx/conf/nginx.conf"配置如下：

user  www www;
worker_processes  8;
worker_cpu_affinity 00000001 00000010 00000100 00001000 00010000 00100000 01000000 10000000;

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

#pid        logs/nginx.pid;

error_log  logs/error.log  notice;

pid        logs/nginx.pid;

events {
    use epoll;
    worker_connections  1024;
}


http {
    include       mime.types;
    default_type  application/octet-stream;

    log_format  main  ‘$remote_addr - $remote_user [$time_local] "$request" ‘
                      ‘$status $body_bytes_sent "$http_referer" ‘
                      ‘"$http_user_agent" "$http_x_forwarded_for"‘;

    #access_log  logs/access.log  main;

    server_tokens   off;

    sendfile        on;
    #tcp_nopush     on;

    #keepalive_timeout  0;
    keepalive_timeout  65;

    gzip  on;

    client_header_buffer_size 4k;

    open_file_cache max=65535 inactive=60s;
    open_file_cache_valid 60s;
    open_file_cache_min_uses 1;

    include vhost/*.conf;
}

"/usr/local/nginx/conf/vhost/default.conf"配置如下(未解析php)：

server {
        listen       80;
        server_name  localhost;

        charset utf-8;

        access_log  logs/default.access.log  main;

        root /data/www/default/;
        index index.html index.htm;

        #error_page  404              /404.html;

        # redirect server error pages to the static page /50x.html
        #
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
}
