Tomcat yum安装和Tomcat编译安装及应用部署-运维那些事

4、LNMT/LAMT

LNMT：


- nginx安装：

~]# yum -y install nginx

- 修改nginx配置文件
~]# cd /etc/nginx/
nginx]# vim nginx.conf
server {
listen 80 default_server;
listen [::]:80 default_server;
server_name localhost;
root /usr/share/nginx/html;

# Load configuration files for the default server block.
include /etc/nginx/default.d/*.conf;

#修改location /进行反代，由于我测试时nginx和tomcat是在同一台server上，所以使用localhost
location / {
proxy_pass http://localhost:8080/;
}

- 验证配置文件并启动nginx
nginx]# nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
nginx]# systemctl start nginx.service
nginx]# ss -tnl
State Recv-Q Send-Q Local Address:Port Peer Address:Port
LISTEN 0 50 *:3306 *:*
LISTEN 0 128 *:80 *:*
LISTEN 0 128 *:22 *:*
LISTEN 0 100 127.0.0.1:25 *:*
LISTEN 0 100 :::8009 :::*
LISTEN 0 128 :::80 :::*
LISTEN 0 100 :::8080 :::*
LISTEN 0 128 :::22 :::*
LISTEN 0 100 ::1:25 :::*
LISTEN 0 1 ::ffff:127.0.0.1:8005 :::*
此时进行访问测试，我访问http时已经不需要指定8080端口，使用默认端口即可访问我后端的tomcat


对HOST主机进行反代

- 服务器端
服务器端本地做好node的解析
~]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.150.138 node2
~]# vim /etc/nginx/nginx.conf
location / {
proxy_pass http://node2:8080/;
}

修改完配置文件后验证并reload nginx服务
~]# nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
~]# systemctl reload nginx.service

- 客户端访问测试，无需在添加8080端口号
~]# curl http://192.168.150.138

<html>
<head>
<title>JSP Test Page</title>
</head>
<body>
hello world from /data/webapps

</body>
</html>

动静分离测试：
- 服务器端：
~]# vim /etc/nginx/nginx.conf
修改nginx配置文件中的location
location / {
}
#如果用户访问jsp资源再进行反代，静态资源nginx自己解析
location ~* \.(jsp|do)$ {
proxy_pass http://node2:8080;
}

nginx]# nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
nginx]# systemctl reload nginx.service

提供一个静态资源给nginx
~]# mv 18.png /usr/share/nginx/html/
访问静态资源，会自动去nginx资源目录：



访问动态jsp资源，会自动去访问tomcat资源目录：



LAMT:


使用httpd的reverse_proxy_module模块反代至tomcat

1、proxy_module, proxy_http_module

- httpd的安装
yum -y install httpd

- 修改httpd配置文档
注释掉主配置文档中的DocumentRoot
~]# vim /etc/httpd/conf/httpd.conf
#DocumentRoot "/var/www/html"
创建http_tomcat.conf的子配置文档
~]# vim /etc/httpd/conf.d/http_tomcat.conf
<VirtualHost *:80>
ServerName tc1.com
ProxyRequests Off
ProxyVia On
ProxyPreserveHost On
<Proxy *>
    Require all granted
</Proxy>
ProxyPass / http://localhost:8080/
ProxyPassReverse / http://localhost:8080/
<Location />
    Require all granted
</Location>
</VirtualHost>

- 验证配置并启动httpd
~]# httpd -t
Syntax OK
~]# systemctl start httpd.service
访问此服务所有的网页均反代至tomcat 8080


2、proxy_module, proxy_ajp_module
httpd反代至tomcat的ajp 8009端口
~]# cd /etc/httpd/conf.d/
conf.d]# ls
autoindex.conf  http_tomcat.conf  README  userdir.conf  welcome.conf
conf.d]# cp http_tomcat.conf ajp_tomcat.conf
conf.d]# mv http_tomcat.conf http_tomcat.conf.bak
conf.d]# vim ajp_tomcat.conf 
<VirtualHost *:80>
    ServerName tc1.com
    ProxyRequests Off
    ProxyVia On
    ProxyPreserveHost On
    <Proxy *>
        Require all granted
    </Proxy>
    ProxyPass / ajp://localhost:8009/
    ProxyPassReverse / ajp://localhost:8009/
    <Location />
        Require all granted
    </Location>
</VirtualHost>

- 验证配置并启动httpd
~]# httpd -t
Syntax OK
~]# systemctl restart httpd.service
访问此服务所有的网页均反代至tomcat 8009
