一、在Nginx服务器上搭建LNMP服务,并且能够对外提供Discuz论坛服务,在Web1、Web2服务器上搭建Tomcat 服务
三、对基于www.benet.com域名的虚拟机主机的nginx服务调优:隐藏nginx版本号,缓存静态图片网页时间为1天,设置防盗链功能
方法二:因为我们根本身就是逻辑卷;所以就不另外添加磁盘了,就在根下面做
六、在Nginx服务器上对基于www.benet.com域名的虚拟机主机设置动静分离由nginx提供静态页面服务,将对 .jsp文件的动态页面请求转发到Tomcat 服务器处理,并实现负载均衡
七、在网关服务器上设置SNAT/DNAT,使client使用网关服务器的ens36接口的IP地址访问也可实现上一题的效果。
拓扑图:
Centos7-5作为Client(12.0.0.12/24);Centos7-1作为网关服务器(配置两块网卡ens33 192.168.246.7/24,ens36 12.0.0.1/24);Centos7-2作为Web1(192.168.246.8/24 提供web1服务);Centos7-3作为Web2(192.168.246.9/24 提供web2服务);Centos7-4作为Nginx服务器(192.168.246.10/24)
五台机器都关闭防火墙、防护
7-1网关服务器配置双网卡

搭好论坛会生成它,注意题目访问www.kgc.com跳到论坛,注意位置,在www.kgc.com域名下面
再编辑域名www.benet.com
- server {
- listen 80;
- server_name www.benet.com;
- root /var/www/html;
- }
- [root@zzzcentos4 conf]#mkdir -p /var/www/html
- [root@zzzcentos4 conf]#cd /var/www/html/
- [root@zzzcentos4 html]#ls
- [root@zzzcentos4 html]#echo hello /var/www/html/ > index.html
- [root@zzzcentos4 html]#cat index.html
- hello /var/www/html/
C:\Windows\System32\drivers\etc
使用http://www.benet.com则访问/var/www/html/目录中的index.html文件的内容
使用http://www.kgc.com/index.php可访问上一题的Discuz论坛页面
[root@zzzcentos4 ~]#vim /usr/local/nginx/conf/nginx.conf
- server {
- listen 80;
- server_name www.benet.com;
- root /var/www/html;
- expires 1d;

- valid_referers none bloaced *.benet.com benet.com;
- if ( $invalid_referer ) {

- }
- }

使用另一台机器检测,就随意选7-2吧
- [root@zzzcentos2 ~]#yum install httpd -y
- [root@zzzcentos2 ~]#cd /var/www/html/
- [root@zzzcentos2 html]#systemctl start httpd
- [root@zzzcentos2 html]#vim index.html

Centos7-1作为网关服务器
①文件系统使用LVM类型
方法一:新加盘做一个LVM类型
- [root@localhost ~]#lsblk
- [root@localhost ~]#echo "- - -" > /sys/class/scsi_host/host0/scan;echo "- - -" > /sys/class/scsi_host/host1/scan;echo "- - -" > /sys/class/scsi_host/host2/scan

- #建逻辑卷 指定名称lvm 指定大小30G 存放在/dev/vg下
- Logical volume "lvm" created.
- [root@localhost ~]#mkfs.xfs /dev/vg/lvm

- exportfs: No options for /opt/nfs *: suggest *(sync) to avoid warning
- [root@localhost ~]#exportfs -v
- /opt/nfs <world>(ro,sync,wdelay,hide,no_subtree_check,sec=sys,secure,root_squash,no_all_squash)
- [root@localhost ~]#hostname zzzcentos1
- [root@localhost ~]#su
- [root@zzzcentos1 ~]#
方法二:因为我们根本身就是逻辑卷;所以就不另外添加磁盘了,就在根下面做
②设置共享目录
- [root@zzcentos1 ~]#mkdir /opt/nfs
- [root@zzcentos1 ~]#vim /etc/exports
- [root@zzcentos1 ~]#cat /etc/exports
- /opt/nfs *
- [root@zzcentos1 ~]#exportfs -r
- exportfs: No options for /opt/nfs *: suggest *(sync) to avoid warning
- [root@zzcentos1 ~]#exportfs -v
- /opt/nfs <world>(ro,sync,wdelay,hide,no_subtree_check,sec=sys,secure,root_squash,no_all_squash)
- [root@zzcentos1 ~]#
③nginx 服务挂载共享目录
编辑脚本:
- #!/bin/bash
- pid=`cat /usr/local/nginx/logs/nginx.pid`
- cd /opt
- mv benet.log /mnt/`date +%F`
- touch benet.log
- kill -USR1 ${pid}
再去页面访问:
编写crontab计划
绝对路径加脚本有执行权限,如上图就可以执行,到此结束
方法二:脚本也可以如下写法
- #!/bin/bash
- day=`date "+%Y-%m-%d"`
- log="/usr/local/nginx/logs"
- pid=`cat /usr/local/nginx/logs/nginx.pid`
-
- mv /${log}/access.log /opt/${day}
- kill -USR1 ${pid}
- sed -i '/.*bbs.*/!p' /opt/${day}
(1)要求配置location匹配请求地址http://www.kgc.com/test/XXXX,使用户访问该路径下的文件时返回/var/share/nginx/html/目录下的文件内容
- location /test {
- alias /var/share/nginx/html;
- }
(2)要求使用rewrite将使用域名www.benet.com 请求以 .php 结尾的访问都跳转到域名www.kgc.com上,而且后面的参数保持不变,比如访问http://www.benet.com/bbs/index.php跳转到http://www.kgc.com/bbs/index.php
①Nginx服务配置
- location ~* \.php$ {
- rewrite ^/(.*) http://www.kgc.com/$1 permanent;
- }
②去浏览器检测:
成功跳转
①Nginx服务器配置
- upstream tomcat {
- server 192.168.246.8:8080;
- server 192.168.246.9:8080;
- }
- location / {
- root /var/www/html;
- index index.html index.htm;
- }
- location ~*\.jsp$ {
- proxy_pass http://tomcat;
- }
②配置Tomcat服务器
tomcat 7-2配置:
tomcat 7-3配置:
- [root@zzzcentos3 ~]#systemctl stop firewalld
- [root@zzzcentos3 ~]#setenforce 0
- [root@zzzcentos3 ~]#cd /usr/local/tomcat/webapps/ROOT/
- [root@zzzcentos3 ROOT]#ls
- asf-logo-wide.svg bg-middle.png bg-upper.png index.jsp tomcat.css tomcat.png tomcat.svg
- bg-button.png bg-nav.png favicon.ico RELEASE-NOTES.txt tomcat.gif tomcat-power.gif WEB-INF
- [root@zzzcentos3 ROOT]#cp index.jsp index.jsp.bak #先备份
- [root@zzzcentos3 ROOT]#ls
- asf-logo-wide.svg bg-nav.png index.jsp tomcat.css tomcat-power.gif
- bg-button.png bg-upper.png index.jsp.bak tomcat.gif tomcat.svg
- bg-middle.png favicon.ico RELEASE-NOTES.txt tomcat.png WEB-INF
- [root@zzzcentos3 ROOT]#echo tomcat 7-3 > index.jsp #输入内容
- [root@zzzcentos3 ROOT]#cat index.jsp
- tomcat 7-3
- [root@zzzcentos3 ROOT]#
③浏览器检测:
理解:
我们想要 客户机 用 网关服务器的ens36接口IP地址(12.0.0.1)去访问www.benet.com/index.jsp,从而得到我们在 Tomcat服务器中配置的 动态页面;
所以这是外网(7-5 IP:12.0.0.12)可以访问内网(7-1 ip: 192.168.246.7),所以我们需要配置的是DNAT
①客户机地址配置
②网关服务器配置
- [root@zzcentos1 network-scripts]#sysctl -a |grep "ip_forward"
- net.ipv4.ip_forward = 0
- net.ipv4.ip_forward_use_pmtu = 0
- sysctl: reading key "net.ipv6.conf.all.stable_secret"
- sctl: reading key "net.ipv6.conf.default.stable_secret"
- ?ysctl: reading key "net.ipv6.conf.ens33.stable_secret"
- sysctl: reading key "net.ipv6.conf.ens36.stable_secret"
- sysctl: reading key "net.ipv6.conf.lo.stable_secret"
- sysctl: reading key "net.ipv6.conf.virbr0.stable_secret"
- sysctl: reading key "net.ipv6.conf.virbr0-nic.stable_secret"
- [root@zzcentos1 network-scripts]#vim /etc/sysctl.conf
- [root@zzcentos1 network-scripts]#sysctl -p
- net.ipv4.ip_forward = 1
- [root@zzcentos1 network-scripts]#
③做SNAT与DNAT
- [root@zzcentos1 network-scripts]#iptables -t nat -A POSTROUTING -o ens36 -s 192.168.246.0/24 -j SNAT --to 12.0.0.1
- [root@zzcentos1 network-scripts]#
- [root@zzcentos1 network-scripts]#iptables -t nat -A PREROUTING -i ens36 -d 12.0.0.1 -p tcp --dport 80 -j DNAT --to 192.168.246.7
- [root@zzcentos1 network-scripts]#iptables -t nat -vnL
- Chain PREROUTING (policy ACCEPT 1 packets, 71 bytes)
- pkts bytes target prot opt in out source destination
- 0 0 DNAT tcp -- ens36 * 0.0.0.0/0 12.0.0.1 tcp dpt:80 to:192.168.246.7
-
- Chain INPUT (policy ACCEPT 1 packets, 71 bytes)
- pkts bytes target prot opt in out source destination
-
- Chain OUTPUT (policy ACCEPT 0 packets, 0 bytes)
- pkts bytes target prot opt in out source destination
-
- Chain POSTROUTING (policy ACCEPT 0 packets, 0 bytes)
- pkts bytes target prot opt in out source destination
- 0 0 SNAT all -- * ens36 192.168.246.0/24 0.0.0.0/0 to:12.0.0.1
- [root@zzcentos1 network-scripts]#
