NGINX+Tomcat负载均衡、动静分离
部署Tomcat页面
Tomcat1
[root@localhost ~]#cd /usr/local/tomcat1/webapps/
[root@localhost webapps]#ls
docs examples host-manager manager ROOT
[root@localhost webapps]#mkdir mm
[root@localhost webapps]#cd mm
[root@localhost mm]#vim test.jsp

Tomcat2
[root@localhost mm]#cd /usr/local/tomcat2/webapps/
[root@localhost webapps]#mkdir mm
[root@localhost webapps]#cd mm
[root@localhost webapps]#vim test.jsp

配置NGINX服务
yum安装NGINX
[root@localhost opt]# cd /etc/yum.repos.d
[root@localhost yum.repos.d]# ls
CentOS-Base.repo CentOS-Debuginfo.repo CentOS-Media.repo CentOS-Vault.repo
CentOS-CR.repo CentOS-fasttrack.repo CentOS-Sources.repo
[root@localhost yum.repos.d]# mkdir repo.bak
[root@localhost yum.repos.d]# mv *.repo repo.bak
[root@localhost yum.repos.d]# ls
repo.bak
[root@localhost yum.repos.d]# vim nginx.repo
[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/centos/$releasever/$basearch/
gpgcheck=1
enabled=1
gpgkey=https://nginx.org/keys/nginx_signing.key
module_hotfixes=true
[root@localhost yum.repos.d]# yum -y install nginx
验证中 : 1:nginx-1.24.0-1.el7.ngx.x86_64 1/1
已安装:
nginx.x86_64 1:1.24.0-1.el7.ngx
完毕！
部署NGINX页面
[root@localhost ~]# cd /usr/share/nginx/html/
[root@localhost html]# ls
50x.html index.html
[root@localhost html]# mkdir mm
[root@localhost html]# cd mm
[root@localhost html]# echo '<h1>this is nginx static web page!</h1>' >test.html
[root@localhost mm]# ls
test.html
实现动静分离
[root@localhost html]# cd /etc/nginx/
[root@localhost nginx]# vim nginx.conf
在 #gzip on;下一行加入
upstream tomcat {
server 192.168.65.101:8080 weight=1
server 192.168.65.102:8080 weight=1
server 192.168.65.102:8082 weight=1
}
[root@localhost nginx]# cd conf.d/
[root@localhost conf.d]# ls
default.conf
[root@localhost conf.d]# vim default.conf
location ~* .*\.jsp$ {
proxy_pass http://tomcat;
proxy_set_header HOST $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
[root@localhost nginx]# nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
[root@localhost conf.d]# systemctl restart nginx
负载均衡
将192.168.65.104主机的nginx.repo拷贝到192.168.65.103
[root@localhost ~]# cd /etc/yum.repos.d
[root@localhost yum.repos.d]# ls
nginx.repo repo.bak
[root@localhost yum.repos.d]# scp nginx.repo 192.168.65.103:`pwd`
