linux安装配置nginx

1、编译环境gcc g++ 开发库之类的需要提前装好

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

2、首先安装PCRE  pcre功能是让nginx有rewrite功能

  检查系统里是否安装了pcre软件

  rpm -qa pcre   如果没有显示说明没有安装  反之安装过

  rpm -e --nodeps pcre  删除pcre

 

  下载PCRE:wget http://downloads.sourceforge.net/project/pcre/pcre/8.35/pcre-8.35.tar.gz

  解压安装包:tar zxvf pcre-8.35.tar.gz

  进入安装包目录:cd pcre-8.35

  编译:./configure

  安装:make && make install

  查看安装版本:pcre-config --version   如果出现版本号,说明安装成功

  

3、安装nginx

  下载nginx:wget http://nginx.org/download/nginx-1.6.2.tar.gz

  解压安装包: tar zxvf nginx-1.6.2.tar.gz

  进入安装包目录:cd nginx-1.6.2

  编译安装:./configure  默认地址 /usr/local/nginx

  安装:make

  安装:make install  

  注:

  第一次编译的时候:

  使用64位的系统第一次编译安装出现

  error while loading shared libraries: libpcre.so.1: cannot open shared object file: No such file or directory这种情况,nginx默认是在lib64下,32为的是在lib下

  查找:find / -name 'libpcre.so.1'  出现 /usr/local/lib/libpcre.so.1,我们建立以符号链接:ln -s /usr/local/lib/libpcre.so.1 /lib64/libpcre.so.1

  这样可以查看nginx版本 /usr/local/nginx/sbin/nginx -v  出现版本号

4、nginx配置

  cd /usr/local/nginx/conf ,把下面的内容覆盖到nginx.conf

复制代码

user www www;
worker_processes 2; #设置值和CPU核心数一致
error_log /usr/local/nginx/logs/nginx_error.log crit; #日志位置和日志级别
pid /usr/local/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 $binary_remote_addr 10m;
 #下面是server虚拟主机的配置
 server
  {
    listen 80;#监听端口
    server_name localhost;#域名
    index index.html index.htm index.php;
    root /usr/local/nginx/html;#站点目录
      location ~ .*\.(php|php5)?$
    {
      #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;
  }

}

复制代码

  可以检测配置的是否正确

  /usr/local/nginx/sbin/nginx -t

  

  说明配置成功

5、启动nginx

  启动的时候有报错,如下

  nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
  nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
  nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
  nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)...

  这说明80接口有被占用,查看接口

  netstat -ntpl

  kill -9 $pid //杀掉进程

  再次启动

       cd /usr/local/nginx/sbin

       ./nginx -s reload

  停止服务器

  .nginx -s stop

  网页访问  127.0.0.1

  至此,安装配置完成!

  在学习过程中配到问题:

  1、在下载安装pcre和nginx中,要用root身份,一般下载到/usr/local/src/,下载到其他地方配置呢?(测试几次没成功)

  2、菜鸟网站中编译nginx的时候 配置安装地址 

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

   编译不成功?(配置安装路径应该没问题,编译的时候报pcrelib.so.0不存在,安装的时候webserver文件没有建立成功,想着应该还是和64位的配置文件路径有关系,有待验证)  

6、卸载nginx

  删除nginx文件即可

  rm -rf /usr/local/nginx
