Linux Web服务器部署LNMT(Linux+Ngnix+MySQL/Mariadb+Tomcat)

操作系统：中标麒麟服务器端操作系统（方法与Cenos相似）

目录

1.安装tomcat

 2.tomcat应用部署

3.安装Nginx

4.同一个项目启动2个tomcat

 5.配置Nginx实现负载均衡

6.MySQL/Mariadb安装

1.安装tomcat

官网下载

https://tomcat.apache.org/

下载tomcat 8
选择Binary Distributions->Core->tar.gz
apache-tomcat-8.5.53.tar.gz

下载好之后

root$ cp apache-tomcat-8.5.53.tar.gz /opt/
root$ cd /opt
root$ tar xf apache-tomcat-8.5.53.tar.gz
root$ rm apache-tomcat-8.5.53.tar.gz
root$ cd apache-tomcat-8.5.53/bin
root$ ./catalina.sh run

运行之后看到下面信息说明启动成功

23-Mar-2020 17:27:43.021 信息 [main] org.apache.catalina.startup.Catalina.start

Server startup in 3181 ms

 2.tomcat应用部署

root$ cd /opt/apache-tomcat-8.5.53/webapps/
root$ cp docs/appdev/sample/sample.war ./
root$ cd ../bin/
root$ ./shutdown.sh
root$ ./catalina.sh run

我们可以通过访问http://localhost:8080进行访问，远程可以通过http://服务器ip地址:8080

如果远程访问出错，可能是防火墙，设置防火墙开放8080端口访问

firewall-cmd --zone=public --add-port=8080/tcp --permanent
systemctl restart firewalld

3.安装Nginx

yum install nginx -y

启动nginx之前，必须保证apache服务为关闭状态，否则nginx启动会失败，因为apache和nginx默认端口都为80

systemctl stop httpd
systemctl start ngnix

我们可以通过http://localhost进行访问

配置Nginx实现反向代理和负载均衡

4.同一个项目启动2个tomcat

再复制一份tomcat,并修改端口号等，进行启动

cd /opt
cp -r apache-tomcat-8.5.53 apache-tomcat-8.5.53-copy2

 修改apache-tomcat-8.5.53-copy2/conf/server.xml，修改三个端口号

将对外端口改为8081，保证和apache-tomcat-8.5.53的对外端口不发生冲突，

    <!-- A "Connector" represents an endpoint by which requests are received
         and responses are returned. Documentation at :
         Java HTTP Connector: /docs/config/http.html
         Java AJP  Connector: /docs/config/ajp.html
         APR (HTTP/AJP) Connector: /docs/apr.html
         Define a non-SSL/TLS HTTP/1.1 Connector on port 8081
    -->
    <Connector port="8081" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />

把8005改成8006

<Server port="8006" shutdown="SHUTDOWN">
  <Listener className="org.apache.catalina.startup.VersionLoggerListener" />
  <!-- Security listener. Documentation at /docs/config/listeners.html
  <Listener className="org.apache.catalina.security.SecurityListener" />
  -->
  <!--APR library loader. Documentation at /docs/apr.html -->
  <Listener className="org.apache.catalina.core.AprLifecycleListener" SSLEngine="on" />
  <!-- Prevent memory leaks due to use of particular java/javax APIs-->
  <Listener className="org.apache.catalina.core.JreMemoryLeakPreventionListener" />
  <Listener className="org.apache.catalina.mbeans.GlobalResourcesLifecycleListener" />

把8009改成8010

    <!-- Define an AJP 1.3 Connector on port 8010 -->
    <!--
    <Connector protocol="AJP/1.3"
               address="::1"
               port="8010"
               redirectPort="8443" />
    -->
 

 

 5.配置Nginx实现负载均衡

vi /etc/nginx/nginx.conf

        include /etc/nginx/default.d/*.conf;

        location / {

      proxy_pass http://tomcat_server;

    }

    }

# Settings for a TLS enabled server.

#    }

}

 配置文件里添加红色部分

systemctl restart nginx

通过查看日志来查看浏览器请求次数

tail -f /opt/apache-tomcat-8.5.53/logs/localhost_access_log.2020-03-23.txt
