一、安装pcre:
复制代码

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

复制代码
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
按 Ctrl+C 复制代码
按 Ctrl+C 复制代码

/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
复制代码

#!/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

复制代码

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:
复制代码

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
}

复制代码

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:
复制代码

#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;

复制代码

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:
复制代码

#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

复制代码

编辑配置文件:

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

内容如下:
复制代码

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
}



复制代码

为Tengine配置一下系统的TCP设置,优化一下:

vi /etc/sysctl.conf

内容如下:
复制代码

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

复制代码

使配置立即生效

/sbin/sysctl -p

制作一个重启全部的脚本

vi /root/restartall
复制代码

#!/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


复制代码

给运行权限

chmod 777 /root/restartall

以后重启服务只需要:

/root/restartall
