一、安装pcre:

cd /usr/local/src
wget http://downloads.sourceforge.net/project/pcre/pcre/8.37/pcre-8.37.tar.gz  tar zxvf pcre-8.37.tar.gz
cd pcre-8.37 ./configure --prefix=/usr/local/pcre
make
make install

二、下载proxy_cache插件

cd /usr/local/srcwget http://labs.frickle.com/files/ngx_cache_purge-2.3.tar.gztar zxvf ngx_cache_purge-2.3.tar.gz

三、安装tengine

yum install openssl openssl-devel -y

cd /usr/local/src
wget http://tengine.taobao.org/download/tengine-2.1.0.tar.gz tar zxvf tengine-2.1.0.tar.gz
cd tengine-2.1.0 ./configure --add-module=/usr/local/src/ngx_cache_purge-2.3 --prefix=/usr/local/nginx --with-http_stub_status_module --with-pcre=/usr/local/src/pcre-8.37 make
make install

/usr/local/nginx/sbin/nginx   #启动nginx
chown nobody.nobody -R /usr/local/nginx/html
chmod 700 -R /usr/local/nginx/html

如果编译的问题的话，看看是不是下面的原因：

./configure: error: the HTTP SSL module requires OpenSSL library原因：安装http_ssl_module模块需要openssl library解决：yum install openssl-devel
./configure: error: the HTTP rewrite module requires the PCRE library.原因：安装http_rewrite_module模块需要先安装PCRE开发包解决：yum install pcre-devel

注意：

--with-pcre=/usr/local/src/pcre-8.37指向的是源码包解压的路径，而不是安装的路径，否则会报错。

--add-module=/usr/local/src/ngx_cache_purge-2.3 是指加载缓存的插件模块

四、设置Tengine开机启动

　　vi /etc/rc.d/init.d/nginx  #编辑启动文件添加下面内容

#!/bin/bash
# Tengine Startup script# processname: nginx
# chkconfig: - 85 15
# description: nginx is a World Wide Web server. It is used to serve
# pidfile: /var/run/nginx.pid
# config: /usr/local/nginx/conf/nginx.conf
nginxd=/usr/local/nginx/sbin/nginx
nginx_config=/usr/local/nginx/conf/nginx.conf
nginx_pid=/usr/local/nginx/logs/nginx.pid
RETVAL=0
prog="nginx"# Source function library.

case "$1" instart)start;;stop)stop;;reload)reload;;restart)stopstart;;status)status $progRETVAL=$?;;*)echo $"Usage: $prog {start|stop|restart|reload|status|help}"exit 1
esac
exit $RETVAL

保存退出

chmod 775 /etc/rc.d/init.d/nginx   #赋予文件执行权限
chkconfig --level 012345 nginx on   #设置开机启动 /etc/rc.d/init.d/nginx restart

五、配置Tengine

将nginx初始配置文件备份，我们要重新创建配置文件.

mv /usr/local/nginx/conf/nginx.conf /usr/local/nginx/conf/nginx.conf.bak

创建nginx用户nginx

groupadd nginx
useradd -g nginx nginx

编辑主配置文件：

vi /usr/local/nginx/conf/nginx.conf

内容如下：

user  www www;
worker_processes 4;   # 工作进程数,为CPU的核心数或者两倍
error_log   logs/error.log  crit; # debug|info|notice|warn|error|crit
pid        logs/nginx.pid;#Specifies the value for maximum file descriptors that can be opened by this process.
worker_rlimit_nofile 65535;
events { use epoll;                             #Linux最常用支持大并发的事件触发机制 worker_connections 65535;
} http { include       mime.types;              #设定mime类型,类型由mime.type文件定义 default_type  application/octet-stream;charset  utf-8;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;  #设定请求缓冲 server_names_hash_bucket_size 256;     #增加,原为128 client_header_buffer_size 256k;           #增加,原为32k large_client_header_buffers 4 256k;       #增加，原为32k #size limits client_max_body_size          10m;        #允许客户端请求的最大的单个文件字节数 client_header_timeout         3m; client_body_timeout           3m; send_timeout                  3m; sendfile                      on; tcp_nopush                    on; keepalive_timeout 60; tcp_nodelay                   on; server_tokens                 on;     #不显示nginx版本信息 limit_conn_zone $binary_remote_addr zone=perip:10m; #添加limit_zone,限制同一IP并发数 #fastcgi_intercept_errors on;            #开启错误页面跳转 include  gzip.conf;                       #压缩配置文件 include  proxy.conf;                    #proxy_cache参数配置文件 include  vhost/*.conf;                   #nginx虚拟主机包含文件目录 include  mysvrhost.conf;               #后端WEB服务器列表文件
}

编辑代理配置文件：

cd /usr/local/nginx/conf/
mkdir vhost
vi /usr/local/nginx/conf/proxy.conf

内容如下：

#注：proxy_temp_path和proxy_cache_path指定的路径必须在同一分区 proxy_temp_path   /tmp/proxy_temp;#设置Web缓存区名称为cache_one，内存缓存空间大小为500MB，1天没有被访问的内容自动清除，硬盘缓存空间大小为30GB。 proxy_cache_path /tmp/proxy_cache levels=1:2 keys_zone=cache_one:500m inactive=1d max_size=30g;client_body_buffer_size    512k;      #原为512k
proxy_connect_timeout      50;          #代理连接超时
proxy_read_timeout         600;         #代理发送超时
proxy_send_timeout         600;         #代理接收超时
proxy_buffer_size          128k;        #代理缓冲大小，原为32k
proxy_buffers              16 256k;     #代理缓冲，原为4 64k
proxy_busy_buffers_size    512k;        #高负荷下缓冲大小，原为128k
proxy_temp_file_write_size 1024m;       #proxy缓存临时文件的大小原为128k
#proxy_ignore_client_abort  on;         #不允许代理端主动关闭连接
proxy_next_upstream error timeout invalid_header http_500 http_503 http_404 http_502 http_504;

编辑主机配置文件：

vi /usr/local/nginx/conf/mysvrhost.conf

内容如下：

upstream cn100 {ip_hash;  #会话保持server 127.0.0.1:8080  max_fails=1 fail_timeout=60s;server 127.0.0.1:9080 max_fails=1 fail_timeout=60s;
}

编辑压缩配置文件：

vi /usr/local/nginx/conf/gzip.conf

内容如下：

#网页GZIP压缩设置
#2012.4.2
#可通过http://tool.chinaz.com/Gzips/检测压缩情况
#
#启动预压缩功能，对所有类型的文件都有效
#gzip_static on;    #开启nginx_static后，对于任何文件都会先查找是否有对应的gz文件#找不到预压缩文件，进行动态压缩
gzip on;
gzip_min_length   1k;  #设置最小的压缩值,单位为bytes.超过设置的min_length的值会进行压缩,小于的不压缩.
gzip_comp_level   3;   #压缩等级设置,1-9,1是最小压缩,速度也是最快的;9刚好相反,最大的压缩,速度是最慢的,消耗的CPU资源也多
gzip_buffers      16 64k;   #设置系统的缓存大小,以存储GZIP压缩结果的数据流,它可以避免nginx频烦向系统申请压缩空间大小
gzip_types text/plain application/x-javascript text/css text/javascript;#关于gzip_types，如果你想让图片也开启gzip压缩，那么用以下这段吧：
#gzip_types text/plain application/x-javascript text/css text/javascript application/x-httpd-php image/jpeg image/gif image/png;#gzip公共配置
gzip_http_version 1.1;      #识别http的协议版本(1.0/1.1)
gzip_proxied      any;      #设置使用代理时是否进行压缩，默认是off的
gzip_vary         on;       #和http头有关系,加个vary头,代理判断是否需要压缩
gzip_disable "MSIE [1-6]."; #禁用IE6的gzip压缩

编辑配置文件：

vi /usr/local/nginx/conf/vhost/cn100.conf

内容如下：

server {listen 80;server_name localhost;#默认启动文件index index.html index.htm;#配置发布目录为/usr/local/tomcat1/webapps/ROOTroot /usr/local/tomcat1/webapps/ROOT;location / {#如果后端的服务器返回502、504、执行超时等错误，自动将请求转发到upstream负载均衡池中的另一台服务器，实现故障转移。proxy_next_upstream http_502 http_504 error timeout invalid_header;proxy_cache cache_one;#对不同的HTTP状态码设置不同的缓存时间proxy_cache_valid  200 304 12h;#以域名、URI、参数组合成Web缓存的Key值，Nginx根据Key值哈希，存储缓存内容到二级缓存目录内proxy_cache_key $host$uri$is_args$args;proxy_set_header Host $host;proxy_set_header X-Real-IP $remote_addr;proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;proxy_pass http://cn100;proxy_pass_header Set-Cookie; #对用户传输Set-Cookie的http头，不然无法支持一些包含cookie的应用，比如我的typecho#过期时间3天expires 3d;}#用于清除缓存，假设一个URL为http://192.168.8.42/test.txt，通过访问http://192.168.8.42/purge/test.txt就可以清除该URL的缓存。location ~ /purge(/.*) {#设置只允许指定的IP或IP段才可以清除URL缓存。allow            127.0.0.1;allow            192.168.0.0/16;deny             all;proxy_cache_purge    cache_one   $host$1$is_args$args;}# 查看nginx的并发连接数配置location /NginxStatus {stub_status on;access_log off;auth_basic "NginxStatus";}#定义Nginx输出日志的路径#access_log /data/logs/nginx_wugk/access.log main;#error_log /data/logs/nginx_wugk/error.log crit;#access_log off; #根据自己的需要选择是否启用access日志，注释掉代表启用error_page 404 /404.html;error_page 500 502 503 504 /404.html;location = /404.html {root html;}limit_conn perip 50; #同一ip并发数为50,超过会返回503
}

为Tengine配置一下系统的TCP设置，优化一下：

vi /etc/sysctl.conf

内容如下：

net.ipv4.ip_forward = 0
net.ipv4.conf.default.rp_filter = 1
net.ipv4.conf.default.accept_source_route = 0
kernel.sysrq = 0
kernel.core_uses_pid = 1
net.ipv4.tcp_syncookies = 1
kernel.msgmnb = 65536
kernel.msgmax = 65536
kernel.shmmax = 68719476736
kernel.shmall = 4294967296
net.ipv4.tcp_max_tw_buckets = 6000
net.ipv4.tcp_sack = 1
net.ipv4.tcp_window_scaling = 1
net.ipv4.tcp_rmem = 4096 87380 4194304
net.ipv4.tcp_wmem = 4096 16384 4194304
net.core.wmem_default = 8388608
net.core.rmem_default = 8388608
net.core.rmem_max = 16777216
net.core.wmem_max = 16777216
net.core.netdev_max_backlog = 262144
net.core.somaxconn = 262144
net.ipv4.tcp_max_orphans = 3276800
net.ipv4.tcp_max_syn_backlog = 262144
net.ipv4.tcp_timestamps = 0
net.ipv4.tcp_synack_retries = 1
net.ipv4.tcp_syn_retries = 1
net.ipv4.tcp_tw_recycle = 1
net.ipv4.tcp_tw_reuse = 1
net.ipv4.tcp_mem = 94500000 915000000 927000000
net.ipv4.tcp_fin_timeout = 1
net.ipv4.tcp_keepalive_time = 30
net.ipv4.ip_local_port_range = 1024 65000#允许系统打开的端口范围

使配置立即生效

/sbin/sysctl -p

制作一个重启全部的脚本

vi /root/restartall

内容如下：

#!/bin/sh##重启memcached进程
service memcached restart#清空日志
rm -f /usr/local/tomcat1/logs/*
rm -f /usr/local/tomcat2/logs/*#清空缓存
rm -rf /tmp/proxy_cache#重启动tomcat
/usr/local/tomcat1/bin/shutdown.sh
/usr/local/tomcat2/bin/shutdown.sh/usr/local/tomcat1/bin/startup.sh
/usr/local/tomcat2/bin/startup.sh#重启nginx
service nginx restart

给运行权限

chmod 777 /root/restartall

以后重启服务只需要：

/root/restartall
