1，安装过程
[root@VM_1_14_centos ~]# cd /data/[root@VM_1_14_centos data]# wget ?http://nginx.org/download/nginx-1.15.7.tar.gz[root@VM_1_14_centos data]# tar -xvf nginx-1.15.7.tar.gz[root@VM_1_14_centos data]# mkdir //usr/local/nginx -p[root@VM_1_14_centos data]# lltotal 1008drwxr-xr-x 9 1001 1001 ???4096 Dec 17 15:16 nginx-1.15.7-rw-r--r-- 1 root root 1026732 Nov 27 22:51 nginx-1.15.7.tar.gz[root@VM_1_14_centos data]# cd nginx-1.15.7/[root@VM_1_14_centos nginx-1.15.7]# ./configure --prefix=/usr/local/nginx[root@VM_1_14_centos nginx-1.15.7]#make&&make install
2，假设服务器外网IP为129.129.129.129，需要通过web访问的index文件是 /usr/index.html，index.html文件内容是：
<!DOCTYPE html><html> ???????<head> ???????????????<meta charset="UTF-8"> ???????????????<title></title> ???????</head> ???????<body> ???????????????<h1>标题1</h1> ???????????????<h2>标题2</h2> ???????????????<h3>标题3</h3> ???????????????<h4>标题4</h4> ???????????????<h5>标题5</h5> ???????????????<h6>标题6</h6> ???????????????<h7>标题7</h7> ???????</body></html>
同时，需要访问某个图片文件/usr/1.png
3，此时我们需要配置nginx
[root@VM_1_14_centos /]# cd /usr/local/nginx/conf/[root@VM_1_14_centos conf]# [root@VM_1_14_centos conf]# [root@VM_1_14_centos conf]# [root@VM_1_14_centos conf]# vim nginx.conf#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; ?#这里需要我们设置web访问的端口 ???????server_name ?129.xxx.xxx.xxx; ??????#这里设置web访问的IP，最终在浏览器访问 ???129.xxx.xxx.xxx:80/index.html ???????#charset koi8-r; ???????#access_log ?logs/host.access.log ?main; ???????location / { ?????????????????????????????????#这里很重要，原因参考下一行 ???????????root ??/usr; ?????????????????????????????#这里更重要，root是指直接访问 IP：port 时，获取文件的根目录，如果上一行设置为 / ，则直接访问IP：port会去拉取 /usr下面的index.html ???????????index ?index.html index.htm; ?????????????#接上一行，如果location后面设置了目录 ?/abc ，则访问IP：port时，会拉取 /usr/abc/index.html. ???????} ???????#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; ???# ???} ???#}}4，启动nginx服务，使用上面的配置文件
[root@VM_1_14_centos sbin]# pwd/usr/local/nginx/sbin[root@VM_1_14_centos sbin]# ./nginx -t #检查配置文件是否正确无误nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is oknginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful[root@VM_1_14_centos sbin]# ./nginx -c /usr/local/nginx/conf/nginx.conf ?#使用上一步配置的nginx.conf启动nginx服务[root@VM_1_14_centos sbin]# ps -aux | grep nginxroot ?????6341 ?0.0 ?0.0 ?20552 ??620 ? ???????Ss ??16:04 ??0:00 nginx: master process ./nginx -c /usr/local/nginx/conf/nginx.confnobody ???6342 ?0.0 ?0.0 ?23088 ?1396 ? ???????S ???16:04 ??0:00 nginx: worker processroot ?????6360 ?0.0 ?0.0 112708 ??980 pts/1 ???S+ ??16:05 ??0:00 grep --color=auto nginx
5，使用浏览器打开对应IP：port
如上图，直接访问IP，会使用默认端口80并拉取index.html.
如果我们需要访问web服务器上的1.png图片，只需要访问url 129.xxx.xxx.xxx:80/1.png，若端口号设置为80时，在浏览器中访问也可以不带端口号。
【Finished】
附：
nginx常用命令
./nginx -s reload 重启nginx
./nginx -s stop 停止nginx
【CentOS 7】nginx配置web服务器
