【Nginx】Nginx配置文件解析
默认配置文件路径:/usr/local/nginx/conf
主配置文件:/usr/local/nginx/conf/nginx.conf
主配置文件框架(nginx.conf) 配置文件的要求是每句结束必须要有分号;,花括号也必须是成对的
#user nobody; 使用什么用户来运行nginx
worker_processes 1; 开启几个进程,进程根据CPU的核心个数来开启,不能任意填写
#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;
#pid logs/nginx.pid; nginx pid存放位置,/usr/local/nginx/logs/nginx.pid
events {
worker_connections 1024; 并发数,默认是1024,并发数和内核参数有关,内核参数openfile默认也是1024,内存参数限制了并发数
}
http { 网站
include mime.types;
default_type application/octet-stream;
#log_format main ‘$remote_addr - $remote_user [$time_local] "$request" ‘ 记录log日志的格式,默认最好不要修改
# ‘$status $body_bytes_sent "$http_referer" ‘
# ‘"$http_user_agent" "$http_x_forwarded_for"‘;
#access_log logs/access.log main; 访问access_log日志的位置
sendfile on;
#tcp_nopush on;
#keepalive_timeout 0;
keepalive_timeout 65;
#gzip on; 页面压缩
server { 一个server{}就是一个网页服务,如果配置文件里边没有了server{},那么启动nginx是无法访问网页
listen 80; 监听端口,默认80
server_name localhost; 域名
#charset koi8-r;
#access_log logs/host.access.log main;
location / { 匹配路径,在访问http://127.0.0.1/的时候就是匹配这个配置中的location /{},匹配到就返回location / {}花括号里边的内容,一个server{}能有多个location{};同样的,在地址栏输入http://127.0.0.0/test 匹配的是配置文件里边的location /test{}
root html; 网页目录,安装路径下的html /usr/local/nginx/html
index index.html index.htm; 默认首页,访问http://127.0.0.1/是时返回的页面
}
#error_page 404 /404.html; 报错页面,可自定义报错页面
# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html; 报错页面
location = /50x.html {
root html;
}
# proxy the PHP scripts to Apache listening on 127.0.0.1:80
#
#location ~ \.php$ {
# proxy_pass http://127.0.0.1;
#}
# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#
#location ~ \.php$ { 匹配以.php结尾的动态页面
# root html; 动态页面位置
# fastcgi_pass 127.0.0.1:9000; 当匹配到了转发给本机的9000端口来处理
# fastcgi_index index.php; 默认首页
# fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
# include fastcgi.conf; 加载外部配置文件
#}
# deny access to .htaccess files, if Apache‘s document root
# concurs with nginx‘s one
#
#location ~ /\.ht {
# deny all;
#}
}
# another virtual host using mix of IP-, name-, and port-based configuration
#
#server { 一个server{}就是一个网页服务,这里的server是虚拟主机
# listen 8000;
# listen somename:8080;
# server_name somename alias another.alias;
# location / {
# root html;
# index index.html index.htm;

#server {
# listen 443 ssl; 加密网站HTTPS,443端口
# server_name localhost;
# ssl_certificate cert.pem; 公钥、证书的文件名,不写路径默认是在/usr/loca/nginx/conf/目录
# ssl_certificate_key cert.key; 私钥
# ssl_session_cache shared:SSL:1m;
# ssl_session_timeout 5m;
# ssl_ciphers HIGH:!aNULL:!MD5;
