nginx 之linux编译安装与启动

文章目录

Nginx安装参考地址

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

系统平台：CentOS release 7 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

[root@localhost opt]# pwd
/opt
[root@localhost opt]# wget http://downloads.sourceforge.net/project/pcre/pcre/8.35/pcre-8.35.tar.gz

2、解压安装包:

[root@localhost opt]# tar zxvf pcre-8.35.tar.gz

3、进入安装包目录

[root@localhost opt]# cd pcre-8.35

4、编译安装

[root@localhost pcre-8.35]# ./configure
[root@localhost pcre-8.35]# make &&

备注,这里有可能执行make && make install命令的时候报下面的错误

make: *** No targets specified and no makefile found.

原因为 没有安装gcc等命令,还是执行上面的命令

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

然后重新执行上面的命令,即:

[root@localhost pcre-8.35]# ./configure
[root@localhost pcre-8.35]# make &&

5、查看pcre版本

[root@localhost opt]# pcre-config --version
8.35

三. 安装 Nginx

1、下载 Nginx，下载地址：http://nginx.org/download/nginx-1.6.2.tar.gz

[root@localhost opt]# pwd
/opt
[root@localhost opt]#  wget http://nginx.org/download/nginx-1.6.2.tar.gz

2、解压安装包

[root@localhost opt]# tar zxvf nginx-1.6.2.tar.gz

3.创建nginx安装目录

[root@localhost opt]# mkdir -p /usr/local/webserver/nginx

4、进入安装包目录

[root@localhost src]# cd nginx-1.6.2

5、编译安装

[root@localhost nginx-1.6.2]# ./configure --prefix=/usr/local/webserver/nginx --with-http_stub_status_module --with-http_ssl_module --with-pcre=/opt/pcre-8.35
[root@localhost nginx-1.6.2]# make
[root@localhost nginx-1.6.2]# make install

6、查看nginx版本

[root@localhost pcre-8.35]# /usr/local/webserver/nginx/sbin/nginx -v
nginx version: nginx/1.6.2

四.创建 Nginx 运行使用的用户 www：

[root@localhost conf]# pwd
/opt/nginx-1.6.2/conf
[root@localhost conf]# /usr/sbin/groupadd www 
[root@localhost conf]# /usr/sbin/useradd -g www www

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

[root@localhost conf]#  cat /usr/local/webserver/nginx/conf/nginx.conf
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;
  }

}

六.检查配置文件nginx.conf的正确性命令：

[root@localhost conf]# /usr/local/webserver/nginx/sbin/nginx -t
nginx: the configuration file /usr/local/webserver/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/webserver/nginx/conf/nginx.conf test is successful

七.启动 Nginx

Nginx 启动命令如下：

[root@localhost conf]# /usr/local/webserver/nginx/sbin/nginx

查看是否启动进程

[root@localhost conf]# ps -ef|grep nginx
root      29772      1  0 01:08 ?        00:00:00 nginx: master process /usr/local/webserver/nginx/sbin/nginx
nobody    29773  29772  0 01:08 ?        00:00:00 nginx: worker process
root      29778   3299  0 01:08 pts/1    00:00:00 grep --color=auto nginx

八.查看启动是否成功

访问站点
从浏览器访问我们配置的站点ip：
localhost
