随着Nginx高性能Web服务器大量被使用,目前Nginx最新稳定版为1.2.6,张宴兄在实际应用中大量使用Nginx,并分享Nginx高性能Web服务器知识,使得Nginx在国内也是飞速的发展。那今天咱们再来温习一下Nginx 动静分离知识,这里仅供参考。一、实践环境:1.系统版本:CentOS6.0 X86_64 2. 3. Nginx版本:Nginx-1.2.6 4. 5. Tomcat版本:Tomcat-6.0.18 二、Nginx安装: 实际环境中安装Nginx,首先需要安装pcre库,然后再安装Nginx:1.#安装pcre支持rewrite库,也可以安装源码,注*安装源码时,指定pcre路径为解压源码的路径,而不是编译后的路径,否则会报错。2. yuminstall pcre-devel pcre -y3. 4. #下载Nginx源码包5. cd /usr/src ;wget -c http://nginx.org/download/nginx-1.2.6.tar.gz6. 7. #解压Nginx源码包8. tar -xzf nginx-1.2.6.tar.gz 9. 10.#进入解压目录,然后sed修改Nginx版本信息为TDTWS 11. cd nginx-1.2.6 ; sed -i -e 's/1.2.6//g' -e 's/nginx\//TDTWS/g' -e 's/"NGINX"/"TDTWS"/g' src/core/nginx.h 12. 13.#预编译Nginx14../configure --user=www --group=www --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module15.#.configure预编译成功后,执行make命令进行编译16. 17. make18.#make执行成功后,执行makeinstall 正式安装19.makeinstall20. #自此Nginx安装完毕!!! 三、配置Nginx: 这里鉴于我的51CTO博客已经有Tomcat安装和配置了,这里忽略,只配置Nginx。1.#进入Nginx应用目录 2. cd /usr/local/nginx/conf 3. #备份原nginx.conf文件 4. mv nginx.conf nginx.bak 创建 vi nginx.conf ,并写入如下内容:1.user www www; 2. worker_processes 8; 3. worker_cpu_affinity 00000001 00000010 00000100 00001000 00010000 00100000 01000000 10000000; 4. pid /usr/local/nginx/nginx.pid; 5. 6. worker_rlimit_nofile 102400; 7. 8. events 9. { 10.use epoll; 11. worker_connections 102400; 12. } 13.http 14.{ 15. include mime.types; 16. 17. default_type application/octet-stream; 18. 19. fastcgi_intercept_errors on; 20. 21. charset utf-8; 22. 23. server_names_hash_bucket_size 128; 24. client_header_buffer_size 4k; 25. large_client_header_buffers 4 32k; 26. client_max_body_size 300m; 27. 28. sendfile on; 29. tcp_nopush on; 30. 31. keepalive_timeout 60; 32. 33. tcp_nodelay on; 34. 35. client_body_buffer_size 512k; 36. proxy_connect_timeout 5; 37. proxy_read_timeout 60; 38. proxy_send_timeout 5; 39. proxy_buffer_size 16k; 40. proxy_buffers 4 64k; 41. proxy_busy_buffers_size 128k; 42. proxy_temp_file_write_size 128k; 43. 44. gzip on; 45. gzip_min_length 1k; 46. gzip_buffers 4 16k; 47. gzip_http_version 1.1; 48. gzip_comp_level 2; 49. gzip_types text/plain application/x-javascript text/css application/xml; 50. gzip_vary on; 51. 52. 53. ###2012-12-19 change nginx logs 54. 55. log_format main '$http_x_forwarded_for - $remote_user [$time_local] "$request" ' 56.

70. upstream tdt_app { 71. server 10.10.141.40:8080 weight=1 max_fails=2 fail_timeout=30s; 72. server 10.10.141.40:8081 weight=1 max_fails=2 fail_timeout=30s; 73. server 10.10.141.41:8080 weight=1 max_fails=2 fail_timeout=30s; 74. server 10.10.141.41:8081 weight=1 max_fails=2 fail_timeout=30s; 75. server 10.10.141.42:8080 weight=1 max_fails=2 fail_timeout=30s; 76. server 10.10.141.42:8081 weight=1 max_fails=2 fail_timeout=30s; 77.} 78. #include引用vhosts.conf,该文件主要用于配置Nginx虚拟主机 79. include vhosts.conf; 80. } 如上nginx.conf配置完毕,继续配置nginx虚拟主机,继续在当前目录创建vhosts.conf vi vhosts.conf 内容如下:1.####www.wuguangke.cn 2. server 3. 4. { 5. listen 80; 6. server_name www.wuguangke.cn; 7. index index.html index.htm; 8. #配置发布目录为/data/www/wugk 9. root /data/www/wugk; 10. 11. location / 12. { 13. proxy_next_upstream http_502 http_504 error timeout invalid_header; 14. proxy_set_header Host $host; 15. proxy_set_header X-Real-IP $remote_addr; 16. proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; 17. proxy_pass http://tdt_wugk; 18. expires 3d; 19. } 20. #动态页面交给http://tdt_wugk,也即我们之前在nginx.conf定义的upstream tdt_wugk 均衡 21. location ~ .*\.(php|jsp|cgi)?$ 22. { 23. proxy_set_header Host $host; 24. proxy_set_header X-Real-IP $remote_addr; 25. proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; 26. proxy_pass http://tdt_wugk; 27. } 28. #配置Nginx动静分离,定义的静态页面直接从Nginx发布目录读取。29. location ~ .*\.(html|htm|gif|jpg|jpeg|bmp|png|ico|txt|js|css)$ 30. { 31. root /data/www/wugk; 32.#expires定义用户浏览器缓存的时间为3天,如果静态页面不常更新,可以设置更长,这样可以节省带宽和缓解服务器的压力33. expires 3d; 34. } 35. #定义Nginx输出日志的路径 36. access_log /data/logs/nginx_wugk/access.log main; 37. error_log /data/logs/nginx_wugk/error.log crit; 38. } 39. 40. ##########chinaapp.sinaapp.com 2012-12-19 41. server 42. 43. { 44. listen 80; 45. server_name chinaapp.sinaapp.com; 46. index index.html index.htm; 47. root /data/www; 48. 49. location / 50. { 51. proxy_next_upstream http_502 http_504 error timeout invalid_header; 52. proxy_set_header Host $host; 53. proxy_set_header X-Real-IP $remote_addr; 54. proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; 55. proxy_pass http://tdt_app; 56. expires 3d; 57. } 58. 59. location ~ .*\.(php|jsp|cgi)?$ 60. { 61. proxy_set_header Host $host; 62. proxy_set_header X-Real-IP $remote_addr; 63. proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; 64. proxy_pass http://tdt_app; 65. } 66. location ~ .*\.(html|htm|gif|jpg|jpeg|bmp|png|ico|txt|js|css)$ 67. { 68. root /data/www/app; 69. expires 3d; 70. } 71. 72. access_log /data/logs/nginx_app/access.log main; 73. error_log /data/logs/nginx_app/error.log crit; 74. } 四、部署测试: 后端配置好Tomcat服务,并启动,发布的程序需同步到Nginx的/data/www对应的目录,因为配置动静分离后,用户请求你定义的静态页面,默认会去nginx的发布目录请求,而不会到后端请求,所以这时候你要保证后端跟前端的程序保持一致,可以使用Rsync做服务端自动同步。1.#检查Nginx配置文件是否配置正确,提示Ok andsuccessful表示正确,如下: 2. [root@WEB-11-151~]# /usr/local/nginx/sbin/nginx -t3. nginx:the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok4. nginx:configuration file /usr/local/nginx/conf/nginx.conf test is successful5. #启动Nginx服务 6. /usr/local/nginx/sbin/nginx 7. #查看Nginx进程是否启动 8. ps -ef |grep nginx 本文只是一个简单的实际案例,里面的配置和参数这里没有做过多的说明,后期会继续更新。本文出自 “烟雨楼台” 博客,请务必保留此出处/article/4239600.html
