Linux下Nginx安装配置实例分析

1、安装编译文件及库文件

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

2、安装pcre，nginx的rewrite的伪静态匹配规则需要用到正则表达式，pcre就是起到这个作用。

下载地址：wgethttp://downloads.sourceforge.net/project/pcre/pcre/8.35/pcre-8.35.tar.gz

如果wget没有安装的话，需要先安装wget，yum -y install wget. wget是linux环境下的下载工具。wget命令的使用见此

3、解压pcre安装包：tar -zxvf pcre-8.35.tar.gz

4、进入安装目录，编译安装

　　cd pcre-8.35

　　./configure

　　make && make install

5、查看pcre版本

　　pcre-config --version

6、下载nginx

　　wgethttp://nginx.org/download/nginx-1.6.2.tar.gz

7、解压并进入安装包

8、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

9、查看nginx版本

10、nginx配置

　　1）、创建nginx 运行使用的用户

　　　　　/usr/sbin/groupadd www

　　　　　/usr/sbin/useradd-g www www

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

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;
 }

}

　　　3）、检查nginx.conf配置文件的正确性

          /usr/local/webserver/nginx/sbin/nginx -t
