为了加快网站的大流量访问速度，公司要求把Nginx更换为Tengine，下面记录下整个安装配置过程：
#安装必要依赖
yum install -y pcre pcre-devel zlib zlib-devel openssl openssl-devel glibc-headers gcc-c++
#安装google-perftools支持依赖
wget http://download.savannah.gnu.org/releases/libunwind/libunwind-0.98.tar.gz
tar xf libunwind-0.98.tar.gz
cd libunwind-0.98
./configure && make && make install
#安装google-perftools
wget https://github.com/gperftools/gperftools/releases/download/gperftools-2.4/gperftools-2.4.tar.gz
tar xf gperftools-2.4.tar.gz
cd gperftools-2.4
./configure --enable-frame-pointers
make && make install
#为google-perftools添加线程目录
mkdir /tmp/tcmalloc
chmod 0777 /tmp/tcmalloc
#下载Tengine最新稳定版本
wget http://tengine.taobao.org/download/tengine-2.1.2.tar.gz
#解压
tar xf tengine-2.1.2.tar.gz
cd tengine-2.1.2
#修改nginx.h，以隐藏版本信息

#配置文件upstream.conf
#负载均衡
#1、轮询（默认）
#每个请求按时间顺序逐一分配到不同的后端服务器，如果后端服务器down掉，能自动剔除。
#2、weight
#指定轮询几率，weight和访问比率成正比，用于后端服务器性能不均的情况。
#例如：
#upstream bakend {
#server 192.168.0.1 weight=10;
#server 192.168.0.2 weight=10;
#}
#3、ip_hash
#每个请求按访问ip的hash结果分配，这样每个访客固定访问一个后端服务器。
#例如：
#upstream bakend {
#ip_hash;
#server 192.168.0.1:88;
#server 192.168.0.2:80;
#}
#每个设备的状态设置为:
#1.down 表示单前的server暂时不参与负载
#2.weight 默认为1.weight越大，负载的权重就越大。
#3.max_fails ：允许请求失败的次数默认为1.当超过最大次数时，返回proxy_next_upstream 模块定义的错误
#4.fail_timeout:max_fails次失败后，暂停的时间。
#5.backup： 其它所有的非backup机器down或者忙的时候，请求backup机器。所以这台机器压力会最轻。
#6.check interval=3000 rise=2 fall=2 timeout=1000 type=http;用于自动判断后端是否可用。
