1 yum -y install gcc gcc-c++ autoconf automake
2 yum -y install zlib zlib-devel openssl openssl-devel pcre pcre-devel
3 wget http://nginx.org/download/nginx-0.8.55.tar.gz
tar -zxvf nginx-0.8.55.tar.gz
cd nginx-0.8.55
./configure
make
make install
4 启动nginx
/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
5 查看nginx进程号
ps -ef |grep nginx
root 6971 1 0 14:19 ? 0 nginx: master process /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
nobody 6972 6971 0 14:19 ? 0 nginx: worker process
(master process 为主进程号
worker process 为次进程号)
6 停止nginx
平滑的停止
Kill -9 '/usr/local/nginx/logs/nginx.pid'
从容的停止
kill - QUIT Nginx 6971
7 重启nginx
重启之前检查配置文件是否正确
/usr/local/nginx/sbin/nginx -t -c /usr/local/nginx/conf/nginx.conf
没有问题的话出现的是这个
the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
configuration file /usr/local/nginx/conf/nginx.conf test is successful
重启nginx
kill -HUB '/usr/local/nginx/logs/nginx.pid'
8 nginx配置文件
user nobody; ------------>使用的用户和组
worker_processes 4; ------------>指定工作衍生的进程数(一般等于CPU总核数或2倍，如cpu是4核的，则worker_processes为8)
#error_log logs/error.log;
#error_log logs/error.log notice;
error_log /var/log/nginx/error.log crit
#error_log logs/error.log info; ------>错误日志路径 和 日志级别 (debug info notice warn error crit)
#pid logs/nginx.pid; ---------->指定pid文件位置
pid /usr/local/nginx/logs/nginx.pid
worker_rlimit_nofile 51200 ------> 指定文件描述符数量 51200
events {
use epoll； ---->使用的网络I/O模型 linux系统推荐采用epoll模型，freeBSD系统推荐采用kqueue模型
worker_connections 51200; ------------>运行的连接数

9 虚拟主机
nginx配置基于IP的虚拟主机
添加虚拟接口：
ifconfig eht0:1 192.168.1.130 netmask 255.255.255.0
ifconfig eth0:2 192.168.1.131 netmask 255.255.255.0
查看
ifconfig
vim /usr/local/nginx/conf/nginx.conf添加如下内容：
http
{
#第1关虚拟主机
server
{
listen 192.168.1.131:80
server_name 192.168.1.131
access_log logs/192.168.1.131.access.log combined;
location /
{
index index.html index.htm index.php;
root /home/xudong/html;
}
}
#第2关虚拟主机
server
{
listen 192.168.1.132:80
server_name 192.168.1.132
access_log logs/192.168.1.132.access.log combined;
location /
{
index index.html index.htm index.php;
root /home/xudong/html;
}
}
#第3关虚拟主机
server
{
listen 192.168.1.133:80;
server_name 192.168.1.133;
access_log logs/192.168.1.133access.log combined;
location /
{
index index.html index.htm index.php;
root /home/xudong/html;
}
}
}
nginx 基于域名的虚拟主机
server
{
listen 80;
server_name www.rongrong.com;
access_log logs/rongrong.com.access.log combined;
location /
{
index index.html index.htm index.php;
root /home/rongrong/pub_html;
}
}
server
{
listen 80;
server_name www.wangjuan.com;
access_log logs/wangjuan.com.access.log combined;
location /
{
index index.html index.htm index.php;
root /home/wangjuan/pub_html;
}
}
10 设定nginx的日志格式
log_format combined '$remote_addr - $remote_user [$time_local] '
'"$request" $status $body_bytes_sent '
' "$http_referer" "$http_user_agent"';
如果经过了反向代理则设置 日志格式
log_format mycombined '$http_x_forwarded_for - $remote_user [$time_local] '
'"$request" $status $body_bytes_sent '
' "$http_referer" "$http_user_agent"';
(1)关闭日志记录
access_log off;
(2)使用默认的日志格式记录；
access_log /var/log/nginx/rongrong.log combined buffer=32k;
(3)使用自定义的格式的日志记录
log_format mycombined '$http_x_forwarded_for - $remote_user [$time_local] '
'"$request" $status $body_bytes_sent '
' "$http_referer" "$http_user_agent"';
access_log /var/log/nginx/access.log mycombined buffer=32k;
$server_name.log
11 nginx切割日志文件
vim /usr/local/nginx/sbin/cu_ngxin_log.sh 内容如下：
#！/bin/bash
#这个脚本每天00：00运行
logs_path="/data1/logs/"
mkdir -p ${logs_path}$(date -d "yesterday" +"%Y") /$(date -d "yesterday" +"%m") /
mv ${logs_path}access.log ${logs_path}$(date -d "yesterday" +"%y") /$(date -d "yesterday" +"%m") /
access_$(date -d "yesterday" +"%Y%m%d").log
kill -USR1 'cat /usr/loca/nginx/logs/nginx.pid'
crontab -e
00 00 * * * /bin/bash /usr/local/nginx/sbin/cut_nginx_log.sh
12 nginx的压缩输出配置
13 nginx的自动列目录配置
server
{
listen 80;
server_name www.wangjuan.com;
access_log logs/wangjuan.com.access.log combined;
location /
autoindex on; ---------------->自动列出目录
autoindex_exact_size on/off ----------->设定索引文件大小的单位（B KB MB GB）
autoindex_localtime on/off ----------->开启本地时间来显示文件时间的功能
{
index index.html index.htm index.php;
root /home/wangjuan/pub_html;
}
}
14 nginx浏览器本地缓存设置
对常见的格式的图片 flash文件则浏览器本地缓存30天，对js,css文件则浏览器本地缓存1小时 代码如下
location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
{
expires 30d;
}
location ~ .*\.(js|css)?$
{
expires 1h;
}
