nginx安装与配置

从今开始，学nginx
#安装pcre
[root@svr3 ~]# tar -xjf pcre-8.02.tar.bz2 -C /usr/src/
[root@svr3 ~]# cd /usr/src/pcre-8.02/
[root@svr3 pcre-8.02]# ./configure && make && make install
#安装nginx
[root@svr3 ~]# useradd -M -s /sbin/nologin nginx
[root@svr3 ~]# tar -xzf nginx-1.0.5.tar.gz -C /usr/src/
[root@svr3 ~]# cd /usr/src/nginx-1.0.5/
[root@svr3 nginx-1.0.5]# ./configure --prefix=/usr/local/nginx --user=nginx --group=nginx
[root@svr3 nginx-1.0.5]# make && make install

[root@svr3 ~]#vim /usr/local/nginx/conf/nginx.conf

现在就配置一台主机,改了以下内容：
    server {
        listen       80;
        server_name svr3.labexam.com 10.1.1.30;
        #charset koi8-r;
        access_log logs/w1.access.log combined;
        location / {
            root   /var/www/w1;
            index index.html index.htm;
        }
#看了下日志
[root@svr3 nginx]# tail /usr/local/nginx/logs/w1.access.log
10.1.1.8 - - [15/Aug/2011:02:21:50 +0800] "GET / HTTP/1.1" 200 8 "-" "Opera/9.80 (Windows NT 5.1; U; zh-cn) Presto/2.9.168 Version/11.50"
10.1.1.8 - - [15/Aug/2011:02:21:50 +0800] "GET /favicon.ico HTTP/1.1" 404 142 "http://svr3.labexam.com/" "Opera/9.80 (Windows NT 5.1; U; zh-cn) Presto/2.9.168 Version/11.50"

===>如何启动nginx? <假定nginx安装在/usr/local/nginx中>
方法1、执行/usr/local/nginx/sbin/nginx -t 检查配置文件是否有误！或是直接执行/usr/local/nginx/sbin/nginx
如果有多个配置文件可以使用指定的配置文件启动：
#/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf

===> nginx的信号控制：
TERM,INT 快速关闭
QUIT 从容关闭
HUP 重启，重新加载配置文件
USR1 重启打开日志，在切割日志时用途大
USR2 平滑升级可执行程序
WINCH 从容关闭进程
