Linux系统运维之负载均衡Tengine
一、介绍
Tengine是由淘宝网发起的Web服务器项目。它在Nginx的基础上,针对大访问量网站的需求,添加了很多高级功能和特性。Tengine的性能和稳定性已经在大型的网站如淘宝网,天猫商城等得到了很好的检验。它的最终目标是打造一个高效、稳定、安全、易用的Web平台。
二、需求
由于目前项目组负责多个项目,甲方的登录方式必须携带域名;故通过tengine配置upstream模块,实现负载均衡(由于目前业务都是单点,所以只是反向代理效果),由于无法提供,故选择四层交换上落VIP,大致拓扑如下:
三、安装环境
CentOS Linux release 7.1 * 2 tengine-2.1.2 yum install openssl openssl-devel pcre pcre-devel -y
四、安装Tengine
解压、编译安装tengine
[root@SIMEt-NgxProxy01 ~]# tar zxvf tengine-2.1.2.tar.gz [root@SIMEt-NgxProxy01 ~]# cd tengine-2.1.2 [root@SIMEt-NgxProxy01 tengine-2.1.2]# ./configure --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module --with-http_gzip_static_module --with-pcre [root@SIMEt-NgxProxy01 tengine-2.1.2]# make -j `grep processor /proc/cpuinfo | wc -l` && make install
配置tengine,主配置文件nginx.conf:
[root@SIMEt-NgxProxy01 ~]# vim /usr/local/nginx/conf/nginx.conf ================================ user nobody nobody; worker_processes auto; worker_rlimit_nofile 65535; #error_log logs/error.log; #error_log logs/error.log notice; #error_log logs/error.log info; pid logs/nginx.pid; events { worker_connections 65535; use epoll; } # load modules compiled as Dynamic Shared Object (DSO) # #dso { # load ngx_http_fastcgi_module.so; # load ngx_http_rewrite_module.so; #} 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; charset uft-8; server_names_hash_bucket_size 256; client_header_buffer_size 32k; large_client_header_buffers 4 128k; #最大缓存为4个128KB client_max_body_size 20m; #允许客户端请求的最大的单个文件字节数 sendfile on; tcp_nopush on; tcp_nodelay on; #keepalive_timeout 0; keepalive_timeout 65; include gzip.conf; #HttpGzip的配置文件 include proxy.conf; #配置代理文件 include vhost/*.conf; #虚拟主机的配置文件 include myupstream.conf; #配置后端的服务器列表文件 } ====================================
Httpgzip配置文件,gzip.conf:
gzip on; gzip_min_length 1k; #设置允许压缩的页面最小字节数。 gzip_buffers 4 16k; #用来存储gzip的压缩结果 gzip_http_version 1.1; #识别HTTP协议版本 gzip_comp_level 2; #设置gzip的压缩比 1-9 1压缩比最小但最快 9相反 gzip_types text/plain application/x-javascript text/css application/xml; #指定压缩类型 gzip_proxied any; #无论后端服务器的headers头返回什么信息,都无条件启用压缩 gzip_vary on; gzip_disable "MSIE [1-6]."; #禁用IE6的gzip压缩
代理配置文件,proxy.conf:
proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; client_body_buffer_size 512k; proxy_connect_timeout 30; proxy_read_timeout 30; proxy_send_timeout 30; proxy_buffer_size 32k; proxy_buffers 4 64k; proxy_busy_buffers_size 128k;
虚拟机配置文件,vhost/*.conf:
server { listen 80; server_name 100.100.100.100; index index.jsp index.htm index.html; location /web { proxy_pass http://ui_web; proxy_pass_header Set-Cookie; } location /android { proxy_pass http://ui_android; proxy_pass_header Set-Cookie; } location /NginxStatus { stub_status on; access_log off; auth_basic "NginxStatus"; } }
负载均衡配置,myupstream.conf:
upstream ui_web { ip_hash; server 10.10.10.10:80 max_fails=1 fail_timeout=60s; } upstream ui_android { ip_hash; server 10.10.10.10:8081 max_fails=1 fail_timeout=60s; }
五、配置启动脚本
由于系统是centos7系列,故配置systemctl脚本:
[root@SIMEt-NgxProxy01 ~]# vim /usr/lib/systemd/system/tengine.service [Unit] Description=The nginx HTTP and reverse proxy server After=syslog.target network.target remote-fs.target nss-lookup.target [Service] Type=forking PIDFile=/usr/local/nginx/logs/nginx.pid ExecStartPre=/usr/local/nginx/sbin/nginx -t ExecStart=/usr/local/nginx/sbin/nginx ExecReload=/bin/kill -s HUP $MAINPID ExecStop=/bin/kill -s QUIT $MAINPID PrivateTmp=true [Install] WantedBy=multi-user.target [root@SIMEt-NgxProxy01 ~]# systemctl restart tengine.service
注:以上为一台负载的配置,另外一台同上。
