一、查看centos的版本
cat?/etc/redhat-release
二、添加資源庫
在 centos 系統上安裝 nginx ，得先去添加一個資源庫：
vim?/etc/yum.repos.d/nginx.repo ??[nginx] ??name=nginx?repo ??baseurl=http://nginx.org/packages/centos/$releasever/$basearch/ ??gpgcheck=0 ??enabled=1
三、安裝nginx
yum?-y?install?nginx
四、測試nginx配置文件是否正確
nginx?-t
打印如下：
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
五、centos7.0+ nginx實現停止、啟動、重啟
systemctl?stop?nginx.service?? systemctl?start?nginx.service systemctl?restart?nginx.service systemctl?status?nginx.service
開機自啟：
systemctl?enable?nginx.service
取消開機自啟：
systemctl?disable?nginx.service
六、nginx.conf配置示例
我的配置：
user?nginx; worker_processes?4; error_log?/var/log/nginx/error.log?warn; pid????/var/run/nginx.pid; events?{ ??worker_connections?1024; } http?{ ??include????/etc/nginx/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"?"$http_x_forwarded_for"'; ??access_log?/var/log/nginx/access.log?main; ??sendfile????on; ??#tcp_nopush???on; ??keepalive_timeout?65; ??#gzip?on; ??include?/etc/nginx/conf.d/*.conf; ??#設定負載均衡的服務器列表 ??upstream?pay_server?{ ????ip_hash; ????server?10.74.248.01:8088?max_fails=2?fail_timeout=2; ????server?10.74.248.02:8088?max_fails=2?fail_timeout=2; ??} ??upstream?print_server?{ ????ip_hash; ????server?10.74.248.03:2001?max_fails=2?fail_timeout=2; ????server?10.74.248.04:2001?max_fails=2?fail_timeout=2; ??} ??upstream?accss_door_server?{ ????ip_hash; ????server?10.74.248.05:2002?max_fails=2?fail_timeout=2; ????server?10.74.248.06:2002?max_fails=2?fail_timeout=2; ??} ?? ??server?{ ????listen?80; ????server_name?wab.kupu.ccoop.com.cn; ????location?/invengo?{ ?????????proxy_pass?http://pay_server; ?????????index?index.jsp?index.html?index.htm; ????} ????location?/invengo/epc?{ ?????????proxy_pass?http://print_server; ?????????index?index.jsp?index.html?index.htm; ????} ????location?/invengo/print?{ ?????????proxy_pass?http://print_server; ?????????index?index.jsp?index.html?index.htm; ????} ????location?/checkout?{ ?????????proxy_pass?http://accss_door_server; ?????????index?index.jsp?index.html?index.htm; ????} ????location?/asset?{ ?????????proxy_pass?http://accss_door_server; ?????????index?index.jsp?index.html?index.htm; ????} ??}
常用的nginx.conf配置：
user?www?www; worker_processes?2; error_log?logs/error.log; #error_log?logs/error.log?notice; #error_log?logs/error.log?info; pid????logs/nginx.pid; events?{ ??use?epoll; ??worker_connections?2048; } http?{ ??include????mime.types; ??default_type?application/octet-stream; ??#log_format?main?'$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?65; ?#?gzip壓縮功能設置 ??gzip?on; ??gzip_min_length?1k; ??gzip_buffers??4?16k; ??gzip_http_version?1.0; ??gzip_comp_level?6; ??gzip_types?text/html?text/plain?text/css?text/javascript?application/json?application/javascript?application/x-javascript?application/xml; ??gzip_vary?on; ? ?#?http_proxy?設置 ??client_max_body_size??10m; ??client_body_buffer_size??128k; ??proxy_connect_timeout??75; ??proxy_send_timeout??75; ??proxy_read_timeout??75; ??proxy_buffer_size??4k; ??proxy_buffers??4?32k; ??proxy_busy_buffers_size??64k; ??proxy_temp_file_write_size?64k; ??proxy_temp_path??/usr/local/nginx/proxy_temp?1?2; ?#?設定負載均衡后臺服務器列表? ??upstream?backend?{? ???????#ip_hash;? ???????server??192.168.10.100:8080?max_fails=2?fail_timeout=30s?;? ???????server??192.168.10.101:8080?max_fails=2?fail_timeout=30s?;? ??} ?#?很重要的虛擬主機配置 ??server?{ ????listen????80; ????server_name?itoatest.example.com; ????root??/apps/oaapp; ????charset?utf-8; ????access_log?logs/host.access.log?main; ????#對?/?所有做負載均衡+反向代理 ????location?/?{ ??????root??/apps/oaapp; ??????index?index.jsp?index.html?index.htm; ??????proxy_pass????http://backend;? ??????proxy_redirect?off; ??????#?后端的web服務器可以通過x-forwarded-for獲取用戶真實ip ??????proxy_set_header?host?$host; ??????proxy_set_header?x-real-ip?$remote_addr;? ??????proxy_set_header?x-forwarded-for?$proxy_add_x_forwarded_for; ??????proxy_next_upstream?error?timeout?invalid_header?http_500?http_502?http_503?http_504; ?????? ????} ????#靜態文件，nginx自己處理，不去backend請求tomcat ????location?~*?/download/?{? ??????root?/apps/oa/fs;? ?????? ????} ????location?~?.*.(gif|jpg|jpeg|bmp|png|ico|txt|js|css)$?? ????{?? ??????root?/apps/oaapp;?? ??????expires???7d;? ????} ????location?/nginx_status?{ ??????stub_status?on; ??????access_log?off; ??????allow?192.168.10.0/24; ??????deny?all; ????} ????location?~?^/(web-inf)/?{?? ??????deny?all;?? ????} ????#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; ????} ??} ?##?其它虛擬主機，server?指令開始 }
