最近在做项目的时候用到了Nginx,刚开始一头雾水,踩了一天坑。在网上找了一些资料,这里做下记录。
Nginx常用指令:
nginx -s quit 优雅停止nginx,有连接时会等连接请求完成再杀死worker进程
nginx -s reload 优雅重启,并重新载入配置文件nginx.conf
nginx -s reopen 重新打开日志文件,一般用于切割日志
nginx -v 查看版本
nginx -t 检查nginx的配置文件
nginx -h 查看帮助信息
nginx -V 详细版本信息,包括编译参数
nginx -c filename 指定配置文件
1、默认的配置项
1 #user nobody; 2 worker_processes 1; 3 4 #error_log logs/error.log; 5 #error_log logs/error.log notice; 6 #error_log logs/error.log info; 7 8 #pid logs/nginx.pid; 9 10 11 events { 12 worker_connections 1024; 13 } 14 15 16 http { 17 include mime.types; 18 default_type application/octet-stream; 19 20 #log_format main ‘$remote_addr - $remote_user [$time_local] "$request" ‘ 21 # ‘$status $body_bytes_sent "$http_referer" ‘ 22 # ‘"$http_user_agent" "$http_x_forwarded_for"‘; 23 24 #access_log logs/access.log main; 25 26 sendfile on; 27 #tcp_nopush on; 28 29 #keepalive_timeout 0; 30 keepalive_timeout 65; 31 32 #gzip on; 33 34 server { 35 listen 80; 36 server_name localhost; 37 38 #charset koi8-r; 39 40 #access_log logs/host.access.log main; 41 42 location / { 43 root html; 44 index index.html index.htm; 45 } 46 47 #error_page 404 /404.html; 48 49 # redirect server error pages to the static page /50x.html 50 # 51 error_page 500 502 503 504 /50x.html; 52 location = /50x.html { 53 root html; 54 } 55 56 # proxy the PHP scripts to Apache listening on 127.0.0.1:80 57 # 58 #location ~ \.php$ { 59 # proxy_pass http://127.0.0.1; 60 #} 61 62 # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000 63 # 64 #location ~ \.php$ { 65 # root html; 66 # fastcgi_pass 127.0.0.1:9000; 67 # fastcgi_index index.php; 68 # fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name; 69 # include fastcgi_params; 70 #} 71 72 # deny access to .htaccess files, if Apache‘s document root 73 # concurs with nginx‘s one 74 # 75 #location ~ /\.ht { 76 # deny all; 77 #} 78 } 79 80 81 # another virtual host using mix of IP-, name-, and port-based configuration 82 # 83 #server { 84 # listen 8000; 85 # listen somename:8080; 86 # server_name somename alias another.alias; 87 88 # location / { 89 # root html; 90 # index index.html index.htm; 91 # } 92 #} 93 94 95 # HTTPS server 96 # 97 #server { 98 # listen 443 ssl; 99 # server_name localhost; 100 101 # ssl_certificate cert.pem; 102 # ssl_certificate_key cert.key; 103 104 # ssl_session_cache shared:SSL:1m; 105 # ssl_session_timeout 5m; 106 107 # ssl_ciphers HIGH:!aNULL:!MD5; 108 # ssl_prefer_server_ciphers on; 109 110 # location / { 111 # root html; 112 # index index.html index.htm; 113 # } 114 #} 115 116 }
2、文件结构
1 ... #全局块 2 3 events { #events块 4 ... 5 } 6 7 http #http块 8 { 9 ... #http全局块 10 server #server块 11 { 12 ... #server全局块 13 location [PATTERN] #location块 14 { 15 ... 16 } 17 location [PATTERN] 18 { 19 ... 20 } 21 } 22 server 23 { 24 ... 25 } 26 ... #http全局块 27 }
1、几个常用配置项:
2、惊群现象:一个网路连接到来,多个睡眠的进程被同时叫醒,但只有一个进程能获得链接,这样会影响系统性能。
3、每个指令必须有分号结束。
