简介

Tengine 可以当成 Nginx Plus,它的健康检查、会话保持都比 Nginx 社区版做得更好。所以打算把线上的换成 Tengine

特性

继承Nginx-1.17.3的所有特性,兼容Nginx的配置;
支持HTTP的CONNECT方法,可用于正向代理场景;
支持异步OpenSSL,可使用硬件如:QAT进行HTTPS的加速与卸载;
增强相关运维、监控能力,比如异步打印日志及回滚,本地DNS缓存,内存监控等;
Stream模块支持server_name指令;
更加强大的负载均衡能力,包括一致性hash模块、会话保持模块,还可以对后端的服务器进行主动健康检查,根据服务器状态自动上线下线,以及动态解析upstream中出现的域名;
输入过滤器机制支持。通过使用这种机制Web应用防火墙的编写更为方便;
支持设置proxy、memcached、fastcgi、scgi、uwsgi在后端失败时的重试次数
动态脚本语言Lua支持。扩展功能非常高效简单;
支持按指定关键字(域名,url等)收集Tengine运行状态;
组合多个CSS、JavaScript文件的访问请求变成一个请求;
自动去除空白字符和注释从而减小页面的体积
自动根据CPU数目设置进程个数和绑定CPU亲缘性;
监控系统的负载和资源占用从而对系统进行保护;
显示对运维人员更友好的出错信息,便于定位出错机器;
更强大的防攻击(访问速度限制)模块;
更方便的命令行参数,如列出编译的模块列表、支持的指令等;
可以根据访问文件类型设置过期时间;
......

安装

jemalloc

jemalloc 用于优化 Nginx 内存管理

wget https://github.com/jemalloc/jemalloc/releases/download/5.2.1/jemalloc-5.2.1.tar.bz2
tar jxvf jemalloc-5.2.1.tar.bz2 
cd jemalloc-5.2.1/
./configure --prefix=/usr/local/jemalloc && make && make install
echo "/usr/local/jemalloc/lib" >> /etc/ld.so.conf
ldconfig 

Tengine
wget https://tengine.taobao.org/download/tengine-2.3.2.tar.gz
tar zxvf tengine-2.3.2.tar.gz 
cd tengine-2.3.2/
useradd www -s /sbin/nologin
./configure --prefix=/usr/local/nginx --user=www --group=www --with-jemalloc=/usr/local/jemalloc --with-http_gzip_static_module --with-http_stub_status_module   --with-http_ssl_module  --with-http_v2_module && make && make install

去掉 ip-hash
    upstream serverLive {

        session_sticky;
    }

健康检查
    upstream serverLive {
