云计算之部署Tomcat服务器

部署Tomcat服务器

安装部署JDK基础环境

yum –y install java-1.8.0-openjdk java-1.8.0-openjdk-headless

java -version

安装部署Tomcat服务器

tar –xf apache-tomcat-8.0.30.tar.gz

mv apache-tomcat-8.0.30 /usr/local/tomcat

mv /dev/random /dev/random.bak

ln –s /dev/urandom /dev/random

/usr/local/tomcat/bin/startup.sh

ss –anptu | grep java

à8005/8009/8080三个端口必须正常运行

实现开机自启，将启动命令写入启动文件中

vim /etc/rc.local

           /usr/local/tomcat/bin/startup.sh

创建测试页面

vim /usr/local/tomcat/webapps/ROOT/test.jsp

   <html>

            <body>

                     <center>

                               Now time is : <%=new java.util.Date()%>

                     </center>

            </body>

   </html>

客户端访问验证

firefox 192.168.1.1:8080/test.jsp

使用tomcat部署虚拟主机

基于两个域名的虚拟主机，www.a.com / www.b.com

# vim /usr/local/tomcat/conf/server.xml

<Host name="www.a.com"  appBase="a" unpackWARs="true" autoDeploy="true">

</Host>

<Host name="www.b.com"  appBase="b" unpackWARs="true" autoDeploy="true">

</Host>

# mkdir -p  /usr/local/tomcat/{a,b}/ROOT

# echo "AAA"   > /usr/local/tomcat/a/ROOT/index.html

# echo "BBB" > /usr/local/tomcat/b/ROOT/index.html

当用户访问 http://www.a.com/test ,打开/var/www/html目录下的内容

vim /usr/local/tomcat/conf/server.xml

    <Host name="www.a.com"  appBase="a" unpackWARs="true" autoDeploy="true">

        <Context path=”/test” docBase=”/var/www/html/” />

    </Host>

客户端测试

# firefox http://www.a.com:8080/test

配置tomcat日志

vim /usr/local/tomcat/conf/server.xml

    <Host name="www.a.com"  appBase="a" unpackWARs="true" autoDeploy="true">

        <Context path=”/test” docBase=”/var/www/html/” />

        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"

               prefix="a_access" suffix=".txt"

               pattern="%h %l %u %t &quot;%r&quot; %s %b" />

    </Host>

    <Host name="www.b.com"  appBase="b" unpackWARs="true" autoDeploy="true">

       <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"

               prefix="b_access" suffix=".txt"

               pattern="%h %l %u %t &quot;%r&quot; %s %b" />

    </Host>

配置tomcat集群

Nginx调度器上配置相应规则

vim /usr/local/nginx/conf/nginx.conf

           http {

                    upstream tomcat {

                             server 192.168.1.1:8080;

                             server 192.168.1.2:8080;

                    }

                    server {

                             listen 80;

                             server_name localhost;

                             location / {

                                   proxy_pass http://tomcat;

                            }

                    }

           }

Tomcat 安全性配置

隐藏tomcat版本信息

# yum –y install java-1.8.0-openjdk-devel

# cd /usr/local/tomcat/lib/

# jar –xf catalina.jar

# vim org/apache/catalina/util/ServerInfo.properties

    server.info=Ktz/1.0.0

    server.number=1.0.0

    server.built=Dec 1 2015 22:30:46 UTC

# vim /usr/local/tomcat/conf/server.xml

    <Connector port="8080" protocol="HTTP/1.1"

        connectionTimeout=”20000” redirectPort=”8443” server=”Ktz” />

tomcat降级启动

默认tomcat使用系统高级管理员账户root启动服务，启动服务尽量使用普通用户，防止别人通过tomcat服务供给服务器。

# useradd –s /sbin/nologin tomcat

# chown –R tomcat:tomcat /usr/local/tomcat/

# su –c /usr/local/tomcat/bin/startup.sh tomcat

# chmod +x /etc/rc.local

# vim /etc/rc.local

# su –c /usr/local/tomcat/bin/startup.sh tomcat
