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
