vim /etc/yum.repose.d/nginx.repo
[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/OS/OSRELEASE/$basearch/
gpgcheck=0
enabled=1
OS改为centos
OSRELEASE改为当前系统版本
[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/centos/6/$basearch/
gpgcheck=0
enabled=1

yum install ngnx

设置额外的参数将被添加到CFLAGS变量
--with-cc-opt='-O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -m64 -mtune=generic -fPIC'
设置的附加参数，链接到系统库
--with-ld-opt='-Wl,-z,relro -Wl,-z,now -pie'

nginx的基础配置语法
user:设置nginx服务的系统使用用户
worker_processes:工作进程数(和cpu核心数保持一致最好)
error_log:错误日志
pid:nginx服务启动时的Pid

events {
worker_connections 每个进程的最大连接数
use io模型
}

页面定制

error_page  /.html;
location = /.html{
  return  "not find!";
}
error_page     /50x.html;
location = /50x.html {
root /usr/share/nginx/html;
}
比如关闭php-fpm后产生502会定位到/50x.html

return http状态码 string
return  内容
return  跳转到的链接
location ~ ^/getjson{
default_type application/json;
return  '{"status":1,"note":"ok"}';
}

location ~* ^/nums/(\d+)([a-z]+)\.html {
set $d $;
set $s $;
return  str:$d$s;
}
http://192.168.1.251/nums/2017abcE.html
str:2017abcE
#防止乱码
location /txt {
default_type text/html;
add_header Content-Type 'text/html;charset=utf-8';
return  "nginx你好";
}

日志类型

error.log access_log

log_format
Syntax: log_format name [escape=default|json] string .....;
Default: log_format combined "....";
Context:http

log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';

access_log /var/log/nginx/access.log main;

nginx变量
HTTP请求变量
arg_PARAMETER,http_HEADER,sent_http_HEADER
内置变量： nginx内置的
自定义变量：自己定义

模块安装

比如要安装 :ngx_http_realip_module

获取之前的在安装编译参数

nginx -V
--group=nginx --user=nginx --prefix=/usr/local/nginx --error-log-path=/var/log/nginx/error.log --http-log-path=/var/log/nginx/access.log --http-client-body-temp-path=/tmp/nginx/client_body --http-proxy-temp-path=/tmp/nginx/proxy --http-fastcgi-temp-path=/tmp/nginx/fastcgi --pid-path=/var/run/nginx.pid --lock-path=/var/lock/nginx --with-http_stub_status_module --with-http_gzip_static_module --with-pcre=/usr/local/src/pcre-8.41

重新编译，编译参数后面加上

--with-http_realip_module

进入源码目录

./configure
--group=nginx --user=nginx --prefix=/usr/local/nginx --error-log-path=/var/log/nginx/error.log --http-log-path=/var/log/nginx/access.log --http-client-body-temp-path=/tmp/nginx/client_body --http-proxy-temp-path=/tmp/nginx/proxy --http-fastcgi-temp-path=/tmp/nginx/fastcgi --pid-path=/var/run/nginx.pid --lock-path=/var/lock/nginx --with-http_stub_status_module --with-http_gzip_static_module --with-pcre=/usr/local/src/pcre-8.41 --with-http_realip_module

make
不make install
make完之后在objs目录下就多了个nginx
替换现有的nginx即可
