首先是下载 此处以 1.8做实验
http://nginx.org/download/nginx-1.8.0.zip
启动方式
绿色文件,无须安装,直接即可启动。 3种启动途径,其实都类似: 一、双击nginx.exe图标,可见黑窗口一闪而过,启动完毕。 二、命令行到nginx目录,输入nginx启动。(注,此方式命令行窗口无任何提示,且被锁定) 三、命令行到nginx目录,输入start nginx启动,此方式不锁定
nginx -s stop // 停止nginx
nginx -s reload // 重新加载配置文件
nginx -s quit // 退出nginx
启动后,默认情况下(无修改配置),可见到有两个nginx的进程,一个是 master process,一个是 worker processes。
默认nginx部署了些静态内容,我们可通过它测试nginx是否在工作。
默认的配置文件(NGINX_HOME/conf/nginx.conf)如下
#user nobody; worker_processes 1; #error_log logs/error.log; #error_log logs/error.log notice; #error_log logs/error.log info; #pid logs/nginx.pid; events { worker_connections 1024; } http { include mime.types; default_type application/octet-stream; #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 logs/access.log main; sendfile on; #tcp_nopush on; #keepalive_timeout 0; keepalive_timeout 65; #gzip on; server { listen 80; server_name localhost; #charset koi8-r; #access_log logs/host.access.log main; location / { root html; index index.html index.htm; } #error_page 404 /404.html; # redirect server error pages to the static page /50x.html # error_page 500 502 503 504 /50x.html; 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$ { # root html; # fastcgi_pass 127.0.0.1:9000; # fastcgi_index index.php; # fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name; # include fastcgi_params; #} # 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 { # listen 8000; # listen somename:8080; # server_name somename alias another.alias; # location / { # root html; # index index.html index.htm; # } #} # HTTPS server # #server { # listen 443 ssl; # server_name localhost; # ssl_certificate cert.pem; # ssl_certificate_key cert.key; # ssl_session_cache shared:SSL:1m; # ssl_session_timeout 5m; # ssl_ciphers HIGH:!aNULL:!MD5; # ssl_prefer_server_ciphers on; # location / { # root html; # index index.html index.htm; # } #} }
通过观察配置文件的非注释项(参考Nginx配置文件nginx.conf中文详解),大概可知:
1、启动了1个worker processes
2、worker_connections,最大并发数为1024
3、include mime.types,引入mime.types文件所声明的文件扩展名与文件类型映射
4、application/octet-stream,默认使用application/octet-stream
5、sendfile,开启高效文件传输模式
6、监听本机“localhost”的80端口
7、映射目录为“当前目录的html目录”
8、出现500、502、503、504错误,则映射到50x.html
浏览地址http://localhost,即可访问其默认页面,即映射到NGINX_HOME/html/index.html
其他静态内容,如html、图片,可自行添加测试。
日志
日志默认位于NGINX_HOME/logs/,可见:
1、access.log,访问日志
2、error.log,异常日志
3、nginx.pid,进程(仅在启动nginx后才有此日志)
异常问题汇总:
- 怎么都无法启动 nginx ?
- 查看默认配置的80端口是否被iis占用?
- 查看配置文件中的相关目录是否正确?
- 查看配置文件...反正问题就出在配置文件.
