构建Nginx+fastcgi+heartbeat高可用
一、准备实验环境二、安装nginx服务器(nginx1,nginx2)
三、安装FastCgi服务器
四、安装http服务器(用于静态服务器)
五、测试nginx是否实现负载均衡以及动静分离
六、配置Nginx的高可用服务
一、准备实验环境
1、IP地址规划
VIP: 172.16.10.8
nginx1:172.16.10.1
nginx2:172.16.10.2
php1:172.16.10.3
php2:172.16.10.4
web:172.16.10.6
2、网络拓扑图

3、服务器配置
nginx1服务器
1234sed -i 's@\(HOSTNAME=\).*@\1nginx1.xiaodong.com@g'/etc/sysconfig/networkecho "172.16.10.2 nginx1.xiaodong.com nginx2">> /etc/hostsssh-keygen -t rsassh-copy-id .ssh/id_rsa.pub ngix2 nginx2服务器
1234sed -i 's@\(HOSTNAME=\).*@\1nginx2.xiaodong.com@g'/etc/sysconfig/networkecho "172.16.10.1 nginx1.xiaodong.com nginx1">> /etc/hostsssh-keygen -t rsassh-copy-id .ssh/id_rsa.pub ngix2 二、安装nginx服务器(nginx1,nginx2)
12345678910111213141516171819202122232425262728# tar xf nginx-1.4.2.tar.gz -C /usr/local/# cd /usr/local/# groupadd -r nginx# useradd -r -g nginx nginx# cd nginx-1.4.2/# ./configure \--prefix=/usr \--sbin-path=/usr/sbin/nginx \--conf-path=/etc/nginx/nginx.conf \--error-log-path=/var/log/nginx/error.log \--http-log-path=/var/log/nginx/access.log \--pid-path=/var/run/nginx/nginx.pid \--lock-path=/var/lock/nginx.lock \--user=nginx \--group=nginx \--with-http_ssl_module \--with-http_flv_module \--with-http_stub_status_module \--with-http_gzip_static_module \--http-client-body-temp-path=/var/tmp/nginx/client/ \--http-proxy-temp-path=/var/tmp/nginx/proxy/ \--http-fastcgi-temp-path=/var/tmp/nginx/fcgi/ \--http-uwsgi-temp-path=/var/tmp/nginx/uwsgi \--http-scgi-temp-path=/var/tmp/nginx/scgi \--with-pcre# make && make install# chmod +x /etc/init.d/nginx# service nginx start 注意:在安装的过程中可能会缺少一些包,但是不必担心,只要使用yum install 就可用解决问题喽
1、nginx支持php的配置(nginx1,nginx2)
12345678910111213141516171819# vim /etc/nginx/fastcgi_paramsfastcgi_param GATEWAY_INTERFACE CGI/1.1;fastcgi_param SERVER_SOFTWAREnginx;fastcgi_param QUERY_STRING $query_string;fastcgi_param REQUEST_METHOD $request_method;fastcgi_param CONTENT_TYPE $content_type;fastcgi_param CONTENT_LENGTH $content_length;fastcgi_param SCRIPT_FILENAME$document_root$fastcgi_script_name;fastcgi_param SCRIPT_NAME $fastcgi_script_name;fastcgi_param REQUEST_URI $request_uri;fastcgi_param DOCUMENT_URI $document_uri;fastcgi_param DOCUMENT_ROOT $document_root;fastcgi_param SERVER_PROTOCOL$server_protocol;fastcgi_param REMOTE_ADDR $remote_addr;fastcgi_param REMOTE_PORT $remote_port;fastcgi_param SERVER_ADDR $server_addr;fastcgi_param SERVER_PORT $server_port;fastcgi_param SERVER_NAME $server_name;~ 2、修改nginx配置文件(nginx1,nginx2),实现动静分离并记录访问者的IP
12345678910111213141516171819202122232425262728293031323334353637383940414243444546474849505152535455565758worker_processes 2;events {worker_connections 1024;}http {includemime.types;default_type application/octet-stream;sendfile on;keepalive_timeout 65;proxy_connect_timeout 5;proxy_read_timeout 60;proxy_send_timeout 5;proxy_buffer_size 16k;proxy_buffers 464k;proxy_busy_buffers_size 128k;proxy_temp_file_write_size 128k;proxy_temp_path /home/temp_dir;proxy_cache_path /home/cache levels=1:2keys_zone=cache_one:200m inactive=1d max_size=30g;gzip on;gzip_min_length 1k;gzip_buffers 416k;gzip_http_version 1.1;gzip_comp_level 2;gzip_types text/plain application/x-javascript text/css application/xml;gzip_vary on;gzip_disable "MSIE \.";upstream web {server 172.16.10.3:9000max_fails=3fail_timeout=30s;server 172.16.10.4:9000max_fails=3fail_timeout=30s;server 172.16.10.1:80backup;}server {listen 80;server_name localhost;location / {roothtml;index index.html index.htm;}error_page500502503504/50x.html;location = /50x.html {roothtml;}location ~ \.php$ {root /web/htdoc;fastcgi_passweb;fastcgi_index index.php;fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;includefastcgi_params;proxy_set_header X-Real-IP $remote_addr;}location ~ \.(html|htm|gif|jpg|jpeg|bmp|png|ico|txt|js|css)$ {proxy_pass http://172.16.10.6;proxy_set_header X-Real-IP $remote_addr;}}} 注释:
第10行-18行 :开启代理缓存功能
第19行-26行: 开启压缩功能
第44行-51行: 转发动态网页
第50 行: 修改头部信息,使得后端web服务器可以看到访问端的地址
第53行—56行: 转发静态网页
三、安装FastCgi服务器
1、php1与php2服务器
12345#yum install gcc libxml2-devel openssl-devel bzip2-devel libmcrypt-devel -y# tar xf php-5.4.19.tar.bz2# cd php-5.4.19# ./configure --prefix=/usr/local/httpd/php --with-mysql=mysqlnd --with-openssl --with-mysqli=mysqlnd --enable-mbstring --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir=/usr --enable-xml --enable-sockets --enable-fpm --with-mcrypt --with-config-file-path=/etc --with-config-file-scan-dir=/etc/php.d --with-bz2# make && make install 2、为php提供配置文件 (php1与php2)
1# cp /usr/local/httpd/php/etc/php-fpm.conf.default/usr/local/httpd/php/etc/php-fpm.conf1# cp php.ini-production /etc/php.ini 3、为php-fpm提供Sysv init脚本,并将其添加至服务列表(php1与php2)
123# cp sapi/fpm/init.d.php-fpm /etc/rc.d/init.d/php-fpm# chmod +x /etc/rc.d/init.d/php-fpm# chkconfig --add php-fpm# chkconfig php-fpm on 4、修改配置文件(php1与php2)
12# vim /usr/local/httpd/php/etc/php-fpm.conflisten = 172.16.10.3:9000 5、启动服务(php1与php2)
1root@php1 php-5.4.19]# service php-fpm start 6、创建php网址目录(php1)
123456# mkdir -pv /web/htdoc/# vim /web/htdoc/index.php php1 7、创建php网址目录(php2)
123456# mkdir -pv /web/htdoc/# vim /web/htdoc/index.php php2 四、安装http服务器(用于静态服务器)
123# yum install httpd -y#echo "stati html 172.16.10.6 "> >/var/www/html/index.html#service httpd start 五、测试nginx是否实现负载均衡以及动静分离
1、访问动态页面测试
http://img1.运维网.com/attachment/201309/200202922.png
http://img1.运维网.com/attachment/201309/200206459.png
2、访问静态页面测试
http://img1.运维网.com/attachment/201309/200252219.png
此时虽然实现了Nginx的负载均衡以后动静分离,但是无法保证nginx服务器的高可用,下面配置nginx的高可用
六、配置Nginx的高可用服务
1、安装heartbeat(nginx1,nginx2)
1# yum install heartbeat -y 2、复制模块文件
12# cd /usr/share/doc/heartbeat-3.0.4/# cp authkeys ha.cf haresources /etc/ha.d/ 注释:
authkeys #是节点之间的认证key文件
ha.cf #heartbeat的主配置文件
haresources #集群资源管理配置文件
3、修改authkeys配置文件
1234567# openssl rand -hex 8>> /etc/ha.d/authkeys 生成随机数# vim authkeysauth 2#1crc#2sha1 HI!#3md5 Hello!2sha1 07cc87ff210e92e0 4、修改权限
1# chmod 600authkeys 5、修改主配置文件
12345678# vim ha.cflogfile /var/log/ha-logkeepalive 2deadtime 30warntime 10ucast eth0 172.16.10.2#指向nginx2的IPnode nginx1.xiaodong.comnode nginx2.xiaodong.com 6、修改资源配置文件
12# vim /etc/ha.d/haresourcesngnix1.xiaodong.com172.16.10.8/16/eth0nginx 注意:此处说明,nginx1为主节点
7、复制配置文件到nginx2
12# cd /etc/ha.d/# scp -p authkeys haresources ha.cf nginx2:/etc/ha.d/ 8、启动heartbeat服务
12# service heartbeat start# service heartbeat start 9、测试heartbeat与nginx是否结合
查看nginx1的启动日志
http://img1.运维网.com/attachment/201309/210931144.png
10、停止nginx1服务
1# service heartbeat stop 当nginx1停掉之后,查看nginx2日志信息
http://img1.运维网.com/attachment/201309/210953889.png
以上信息反馈出来了,当nginx1 down掉之后,nginx2立刻检测到,并启动nginx服务,保证了nginx的高可用性。
