NGINX的安装与配置

NGINX的安装与配置

Nginx 安装

系统平台:CentOS release 7.6 (Final) 64位。

一、安装编译工具及库文件

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

二、首先要安装 PCRE

PCRE 作用是让 Nginx 支持 Rewrite 功能。

1、下载 PCRE 安装包,下载地址: http://downloads.sourceforge.net/project/pcre/pcre/8.35/pcre-8.35.tar.gz

2、解压安装包:

tar zxvf pcre-8.35.tar.gz

3、进入安装包目录

cd pcre-8.35

4、编译安装 

./configure
make && make install

5、查看pcre版本

pcre-config --version

安装 Nginx

1、下载 Nginx,下载地址:https://nginx.org/en/download.html

cd /usr/local/src/
wget http://nginx.org/download/nginx-1.22.0.tar.gz

2、解压缩包

tar zxf nginx-1.22.0.tar.gz

3、进入安装包目录

cd nginx-1.22.0

4、编译安装

./configure --prefix=/usr/local/webserver/nginx --with-http_stub_status_module --with-http_ssl_module --with-pcre=/usr/local/src/pcre-8.35
make && make install

5、查看nginx版本

/usr/local/webserver/nginx/sbin/nginx -v

nginx version: nginx/1.22.0 #反馈结果

nginx安装完成。

Nginx 配置

1、创建 Nginx 运行使用的用户 www:

groupadd www 
useradd -g www www

2、配置nginx.conf ,将/usr/local/webserver/nginx/conf/nginx.conf替换为以下内容:

vim /usr/local/webserver/nginx/conf/nginx.conf

ggdG #清空所有内容 命令模式下输入
#替换内容

user www www;
worker_processes 2; #设置值和CPU核心数一致
error_log /usr/local/webserver/nginx/logs/nginx_error.log crit; #日志位置和日志级别
pid /usr/local/webserver/nginx/nginx.pid;
#Specifies the value for maximum file descriptors that can be opened by this process.
worker_rlimit_nofile 65535;
events
{
  use epoll;
  worker_connections 65535;
}
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';
  
#charset gb2312;
     
  server_names_hash_bucket_size 128;
  client_header_buffer_size 32k;
  large_client_header_buffers 4 32k;
  client_max_body_size 8m;
     
  sendfile on;
  tcp_nopush on;
  keepalive_timeout 60;
  tcp_nodelay on;
  fastcgi_connect_timeout 300;
  fastcgi_send_timeout 300;
  fastcgi_read_timeout 300;
  fastcgi_buffer_size 64k;
  fastcgi_buffers 4 64k;
  fastcgi_busy_buffers_size 128k;
  fastcgi_temp_file_write_size 128k;
  gzip on; 
  gzip_min_length 1k;
  gzip_buffers 4 16k;
  gzip_http_version 1.0;
  gzip_comp_level 2;
  gzip_types text/plain application/x-javascript text/css application/xml;
  gzip_vary on;
 
  #limit_zone crawler $binary_remote_addr 10m;
 #下面是server虚拟主机的配置
 server
  {
    listen 80;#监听端口
    server_name localhost;#域名
    index index.html index.htm index.php;
    root /usr/local/webserver/nginx/html;#站点目录
      location ~ .*\.(php|php5)?$
    {
      #fastcgi_pass unix:/tmp/php-cgi.sock;
      fastcgi_pass 127.0.0.1:9000;
      fastcgi_index index.php;
      include fastcgi.conf;
    }
    location ~ .*\.(gif|jpg|jpeg|png|bmp|swf|ico)$
    {
      expires 30d;
  # access_log off;
    }
    location ~ .*\.(js|css)?$
    {
      expires 15d;
   # access_log off;
    }
    access_log off;
  }

}

环境变量配置

1、需要把nginx所在的目录加入系统变量中

vim /etc/profile

PATH=$PATH:/usr/local/webserver/nginx/sbin/ #添加到export PATH的上面

:wq #保存退出

source /etc/profile #使配置文件生效

2、测试环境变量配置

nginx -v #显示版本号
nginx -t #检查配置文件

3、启动NGINX

systemctl restart nginx
