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。
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:
CentOS Linux release 7.1 * 2
tengine-2.1.2
yum install openssl openssl-devel pcre pcre-devel -y
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:
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;
}
#dso {
#}
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;
}
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

PIDFile=/usr/local/nginx/logs/nginx.pid
ExecStartPre=/usr/local/nginx/sbin/nginx -t
ExecStart=/usr/local/nginx/sbin/nginx

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。
