Nginx 安装配置

Nginx("engine x")是一款是由俄罗斯的程序设计师Igor Sysoev所开发高性能的 Web和 反向代理 服务器，也是一个 IMAP/POP3/SMTP 代理服务器。

在高连接并发的情况下，Nginx是Apache服务器不错的替代品。

Nginx 配置

创建 Nginx 运行使用的用户 www：

[root@bogon conf]# /usr/sbin/groupadd www
[root@bogon conf]# /usr/sbin/useradd -g www www
配置nginx.conf ，将/usr/local/webserver/nginx/conf/nginx.conf替换为以下内容

[root@bogon 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;
}

}

检查配置文件nginx.conf的正确性命令：

[root@bogon conf]# /usr/local/webserver/nginx/sbin/nginx -t
