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 404 /404.html; location = /404.html{ return 404 "not find!"; } error_page 500 502 503 504 /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 200 内容 return 301 跳转到的链接 location ~ ^/getjson{ default_type application/json; return 200 '{"status":1,"note":"ok"}'; } location ~* ^/nums/(\d+)([a-z]+)\.html { set $d $1; set $s $2; return 200 str:$d$s; } http://192.168.1.251/nums/2017abcE.html str:2017abcE #防止乱码 location /txt { default_type text/html; add_header Content-Type 'text/html;charset=utf-8'; return 200 "nginx你好"; }
日志类型
error.log access_log
log_format Syntax: log_format name [escape=default|json] string .....; Default: log_format combined "...."; Context:http log_format main '$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
