    ▪Centos下yum安装nginx+PHP-FPM+eAccelerator+mysql      首先，添加安装源 Centos 默认官方源中没有nginx 和 php-fpm，所以必须添加第三方源，否则就只能自己编译了。 添加[CentALT]源 在/etc/yum.repo.d 目下创建 alt.ru.repo 文件内容如下：   代码如下: [Ce.........

    ▪nginx与tomcat环境中获取真实IP的办法      第一步：在nginx.conf中配置反向代理时把真实IP带上，例如： server {     listen 80;     server_name  boyan.com;     location ~ ^/(WEB-INF)/ {         deny all;      }     location / {       proxy_p.........

    ▪将nginx制作为linux系统服务      把Nginx加为linux的系统服务，其实就是创建一个启动管理脚本，类似于httpd可以使用service启动与停止，可以使用chkconfig配置服务一样。   代码如下: #!/bin/sh # # nginx - this script starts and stops the.........

代码如下:

[CentALT]
name=CentALT Packages for Enterprise Linux 5 - $basearch
baseurl=http://centos.alt.ru/repository/centos/5/$basearch/
enabled=1
gpgcheck=0

代码如下:

worker_processes 4;
#启用epoll
worker_rlimit_nofile 51200;
events {
 worker_connections 51200;
 use epoll;
}
#参数调整
 sendfile on;
 tcp_nopush on;
 tcp_nodelay  on;
 server_tokens off;
 keepalive_timeout 50;
 server_names_hash_bucket_size 128;
 client_header_buffer_size 32k;
 large_client_header_buffers 4 32k;
 client_max_body_size 50m;
#fastcgi优化
 fastcgi_connect_timeout 300;
 fastcgi_send_timeout 300;
 fastcgi_read_timeout 300;
 fastcgi_buffer_size64k;
 fastcgi_buffers 4 64k;
 fastcgi_busy_buffers_size 128k;
 fastcgi_temp_file_write_size 256k;
#开启gzip并优化
 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;
 

代码如下:

max_allowed_packet = 3M
thread_stack = 64K
thread_cache_size = 8
table_cache  = 3
query_cache_limit = 1M

net.ipv4.tcp_tw_reuse = 1
net.ipv4.tcp_tw_recycle = 1

/etc/init.d/php-fpm start
/etc/init.d/mysqld start
chkconfig nginx on
chkconfig php-fpm on
