CentOS-6.5安装配置Tengine

一、安装pcre:

cd /usr/local/src
wget http://downloads.sourceforge.net/project/pcre/pcre/8.34/pcre-8.34.tar.gz

tar zxvf pcre-8.34.tar.gz
cd pcre-8.34
./configure --prefix=/usr/local/pcre
make
make install

二、下载proxy_cache插件

cd /usr/local/src

wget http://labs.frickle.com/files/ngx_cache_purge-2.1.tar.gz

tar zxvf ngx_cache_purge-2.1.tar.gz

三、安装tengine

yum install openssl openssl-devel -y

cd /usr/local/src
wget http://tengine.taobao.org/download/tengine-2.0.0.tar.gz
tar zxvf tengine-2.0.0.tar.gz
cd tengine-2.0.0
./configure --add-module=/usr/local/src/ngx_cache_purge-2.1 --prefix=/usr/local/nginx --with-http_stub_status_module --with-pcre=/usr/local/src/pcre-8.34 
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-8.21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-2.1 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.
. /etc/rc.d/init.d/functions
# Source networking configuration.
. /etc/sysconfig/network
# Check that networking is up.
[ ${NETWORKING} = "no" ] && exit 0
[ -x $nginxd ] || exit 0
# Start nginx daemons functions.
start() {
if [ -e $nginx_pid ];then
echo "tengine already running...."
exit 1
fi
echo -n $"Starting $prog: "
daemon $nginxd -c ${nginx_config}
RETVAL=$?
echo
[ $RETVAL = 0 ] && touch /var/lock/subsys/nginx
return $RETVAL
}
# Stop nginx daemons functions.
stop() {
echo -n $"Stopping $prog: "
killproc $nginxd
RETVAL=$?
echo
[ $RETVAL = 0 ] && rm -f /var/lock/subsys/nginx /usr/local/nginx/logs/nginx.pid
}
reload() {
echo -n $"Reloading $prog: "
#kill -HUP `cat ${nginx_pid}`
killproc $nginxd -HUP
RETVAL=$?
echo
}
# See how we were called.
case "$1" in
start)
start
;;
stop)
stop
;;
reload)
reload
;;
restart)
stop
start
;;

status)
status $prog
RETVAL=$?
;;
*)
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  

四、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www

groupadd www
useradd -g www www

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          50m;    #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/ROOT
root /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

#!/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
