一直以来感觉技术水平偏弱,于是乎,挑了nginx作为练手,希望能通过这个的锻炼,真正切切的提高自己的水平,现在nginx网上的资料已经非常多了,今天就开始做分析nginx的准备工作。
我的nginx版本:1.2.9
源码阅读工具:source Insight
nginx目录
源码目录
1. core // 是Nginx服务器的主干部分,包含基本数据结构,main()函数,写log等等
2. event // 事件驱动模型以及相关代码
3. http // 不用多解释了,肯定与http的实现相关了
4. mail // 邮件代理相关了
5. misc //C++兼容性测试和google perftools模块的源码
6. os // 包装(是包装)了系统的函数调用,Unix网络编程里面把这个方式叫做“包裹函数”
此外,auto这个文件夹下,都是自动化配置脚本
现在我们先来看nginx是如何使用的
官方配置详解
nginx.conf该文件是启动nginx的主要配置文件
user www www; ## Default: nobody
worker_processes 5; ## Default: 1
error_log logs/error.log;
pid logs/nginx.pid;
worker_rlimit_nofile 8192;
events {
worker_connections 4096; ## Default: 1024
}
http {
include conf/mime.types;
include /etc/nginx/proxy.conf;
include /etc/nginx/fastcgi.conf;
index index.html index.htm index.php;
default_type application/octet-stream;
log_format main '$remote_addr - $remote_user [$time_local] $status '
'"$request" $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_log logs/access.log main;
sendfile on;
tcp_nopush on;
server_names_hash_bucket_size 128; # this seems to be required for some vhosts
server { # php/fastcgi
listen 80;
server_name domain1.com www.domain1.com;
access_log logs/domain1.access.log main;
root html;
location ~ \.php$ {
fastcgi_pass 127.0.0.1:1025;
}
}
server { # simple reverse-proxy
listen 80;
server_name domain2.com www.domain2.com;
access_log logs/domain2.access.log main;
# serve static files
location ~ ^/(images|javascript|js|css|flash|media|static)/ {
root /var/www/virtual/big.server.com/htdocs;
expires 30d;
}
# pass requests for dynamic content to rails/turbogears/zope, et al
location / {
proxy_pass http://127.0.0.1:8080;
}
}
upstream big_server_com {

}
server { # simple load balancing
listen 80;
server_name big.server.com;
access_log logs/big.server.access.log main;
location / {
proxy_pass http://big_server_com;
}
}
}
