linux系統爲Centos 64位javascript
1、安裝
[root@cuiqq local]# mkdir /usr/local/nginx
[root@cuiqq local]# cd /usr/local/nginx/php
[root@cuiqq nginx]# wget http://nginx.org/download/nginx-1.17.5.tar.gzcss
[root@cuiqq nginx]# tar -zxvf nginx-1.17.5.tar.gzhtml
[root@cuiqq nginx]# cd nginx-1.17.5java
[root@cuiqq nginx-1.17.5]# ./configure node
[root@cuiqq nginx-1.17.5]# make installlinux
[root@cuiqq bin]# cd /usr/local/nginx/nginx
[root@cuiqq nginx]# rm -rf nginx-1.17.5 nginx-1.17.5.tar.gzweb
[root@cuiqq nginx]# cp sbin/nginx /usr/local/bin/json
[root@cuiqq nginx]# nginx
[root@cuiqq nginx]# ps -ef | grep nginx
root 19784 1 0 00:48 ? 00:00:00 nginx: master process nginx
nobody 19785 19784 0 00:48 ? 00:00:00 nginx: worker process
root 20146 20751 0 00:48 pts/1 00:00:00 grep nginx
======安裝完成=====
2、nginx命令
進入/sbin 目錄後執行命令：
nginx啓動 1、啓動nginx：nginx 2、關閉nginx：nginx -s stop 3、重啓nginx：nginx -s reload
多種中止方式：
中止操做是經過向nginx進程發送信號來進行的
查詢nginx主進程號
ps -ef | grep nginx
root 20191 1 0 21:00 ? 00:00:00 nginx: master process nginx
nobody 20192 20191 0 21:00 ? 00:00:00 nginx: worker process
在進程列表裏 面找master進程，它的編號就是主進程號了。
發送信號從容中止Nginx
kill -QUIT 主進程號
快速中止Nginx
kill -TERM 主進程號
強制中止Nginx
pkill -9 nginx
另外， 若在nginx.conf配置了pid文件存放路徑則該文件存放的就是Nginx主進程號，若是沒指定則放在nginx的logs目錄下。有了pid文 件，咱們就不用先查詢Nginx的主進程號，而直接向Nginx發送信號了，命令以下：
kill -信號類型 '/usr/nginx/logs/nginx.pid'
平滑重啓
若是更改了配置就要重啓Nginx，要先關閉Nginx再打開？不是的，能夠向Nginx 發送信號，平滑重啓。平滑重啓命令：
kill -HUP 主進程號或進程號文件路徑
或者使用
/usr/nginx/sbin/nginx -s reload
判斷Nginx配置是否正確命令
nginx -t -c /usr/nginx/conf/nginx.conf或者
[root@cuiqq conf]# nginx -t nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
3、配置nginx.conf
nginx配置分爲五大區域，main、event、http、service、location。咱們經常使用的是後面三個
做用：全局做用域
##全局塊 開始##
user nobody; #配置容許運行nginx服務器的用戶和用戶組,這裏的nobody就是上面查看nginx進程時顯示的nobody
worker_processes number | auto ; #nginx進程參數，一般設置成和CPU的數量相等 也能夠設置成auto 演示v5
error_log logs/error.log; #錯誤日誌存放路徑
#error_log logs/error.log notice;
#error_log logs/error.log info;
pid logs/nginx.pid; #nginx pid記錄位置
##全局塊 結束##
Event塊配置
做用：Nginx服務器與用戶的網絡鏈接
events {
worker_connections 1024; #鏈接數上限，單個後臺進程最大併發連接數默認1024
use epoll; #工做模式：epoll多路複用IO中的一種方式，僅適用於linux2.6以上內核，提升nginx性能 uname –a 查看linux內核
}
1 user www www; 2 # 工做進程個數，可配置多個 3 worker_processes auto; 4 5 error_log /data/wwwlogs/error_nginx.log crit; 6 pid /var/run/nginx.pid; 7 worker_rlimit_nofile 51200; 8 9 events { 10 use epoll; 11 # 單個進程最大鏈接數 12 worker_connections 51200; 13 multi_accept on; 14 } 15 16 http { 17 include mime.types; 18 default_type application/octet-stream; 19 server_names_hash_bucket_size 128; 20 client_header_buffer_size 32k; 21 large_client_header_buffers 4 32k; 22 client_max_body_size 1024m; 23 client_body_buffer_size 10m; 24 sendfile on; 25 tcp_nopush on; 26 keepalive_timeout 120; 27 server_tokens off; 28 tcp_nodelay on; 29 30 fastcgi_connect_timeout 300; 31 fastcgi_send_timeout 300; 32 fastcgi_read_timeout 300; 33 fastcgi_buffer_size 64k; 34 fastcgi_buffers 4 64k; 35 fastcgi_busy_buffers_size 128k; 36 fastcgi_temp_file_write_size 128k; 37 fastcgi_intercept_errors on; 38 39 #Gzip Compression 40 gzip on; 41 gzip_buffers 16 8k; 42 gzip_comp_level 6; 43 gzip_http_version 1.1; 44 gzip_min_length 256; 45 gzip_proxied any; 46 gzip_vary on; 47 gzip_types 48 text/xml application/xml application/atom+xml application/rss+xml application/xhtml+xml image/svg+xml 49 text/javascript application/javascript application/x-javascript 50 text/x-json application/json application/x-web-app-manifest+json 51 text/css text/plain text/x-component 52 font/opentype application/x-font-ttf application/vnd.ms-fontobject 53 image/x-icon; 54 gzip_disable "MSIE [1-6]\.(?!.*SV1)"; 55 56 #If you have a lot of static files to serve through Nginx then caching of the files' metadata (not the actual files' contents) can save some latency. 57 open_file_cache max=1000 inactive=20s; 58 open_file_cache_valid 30s; 59 open_file_cache_min_uses 2; 60 open_file_cache_errors on; 61 62 ######################## default ############################ 63 # 服務器集羣名稱自定義的 和下面的location地址對應 64 upstream myServer { 65 # weigth參數表示權值，權值越高被分配到的概率越大 66 # server 127.0.0.1:8080 weight=1; 67 # server 127.0.0.1:8060 weight=1; 68 server 47.93.10.184:8080; 69 server 47.93.10.184:8081; 71 } 72 73 # 每個server至關於一個代理服務器 74 server { 75 # 監聽端口，默認80 76 listen 8848; 77 # 當前服務的域名，能夠有多個，用空格分隔(咱們是本地因此是localhost) www.cuiqq.cn 也能夠是 ip 78 server_name localhost; 79 #server_name _; 80 access_log /data/wwwlogs/access_nginx.log combined; 81 root /data/wwwroot/default; 82 # 當沒有指定主頁時，默認會選擇這個指定的文件，可多個，空格分隔 83 index index.html index.htm index.php; 84 # 表示匹配的路徑，這時配置了/表示全部請求都被匹配到這裏 ***重點：路徑匹配規則會有單獨一節說明*** 85 location / { 86 # 請求轉向自定義的服務器列表 87 proxy_pass http://myServer; 88 } 89 location /nginx_status { 90 stub_status on; 91 access_log off; 92 allow 127.0.0.1; 93 deny all; 94 } 95 location ~ [^/]\.php(/|$) { 96 #fastcgi_pass remote_php_ip:9000; 97 fastcgi_pass unix:/dev/shm/php-cgi.sock; 98 fastcgi_index index.php; 99 include fastcgi.conf; 100 } 101 location ~ .*\.(gif|jpg|jpeg|png|bmp|swf|flv|mp4|ico)$ { 102 expires 30d; 103 access_log off; 104 } 105 location ~ .*\.(js|css)?$ { 106 expires 7d; 107 access_log off; 108 } 109 location ~ /\.ht { 110 deny all; 111 } 112 } 113 114 ########################## conf.d ############################# 115 include conf.d/*.conf; ##將另一個文件包含到當前文件中，通常會放一些 upstream 116 }
