linux安装多个Tomcat实现负载均衡

痛定思痛。 2022-04-22 22:06 208阅读 0赞

1，复制原tomcat并重命名tomcat

<table> 
 <tbody> 
 <tr> 
 <td> 1 </td> 
 <td> <code>cp</code>&nbsp;<code>/usr/local/tomcat</code>&nbsp;&nbsp;&nbsp;<code>/usr/local/tomcat2</code> </td> 
 </tr> 
 </tbody> 
</table>

修改外部环境

<table> 
 <tbody> 
 <tr> 
 <td> 1 2 3 4 5 6 7 8 9 10 11 12 13 </td> 
 <td> <code>vim&nbsp;</code><code>/etc/profile</code> &nbsp; <code>export</code>&nbsp;<code>JAVA_HOME=</code><code>/usr/java/jdk1</code><code>.8.0_73</code> <code>export</code>&nbsp;<code>PATH=$JAVA_HOME</code><code>/bin</code><code>:$PATH</code> <code>export</code>&nbsp;<code>CLASSPATH=.:$JAVA_HOME</code><code>/lib/dt</code><code>.jar:$JAVA_HOME</code><code>/lib/tool</code><code>.jar</code> &nbsp; <code>export</code>&nbsp;<code>TOMCAT_HOME=</code><code>/usr/local/tomcat</code> <code>export</code>&nbsp;<code>CATALINA_HOME=</code><code>/usr/local/tomcat</code> <code>export</code>&nbsp;<code>CATLINA_BASE=</code><code>/usr/local/tomcat</code> &nbsp; <code>export</code>&nbsp;<code>TOMCAT_HOME_2=</code><code>/usr/local/tomcat2</code> <code>export</code>&nbsp;<code>CATALINA_HOME_2=</code><code>/usr/local/tomcat2</code> <code>export</code>&nbsp;<code>CATLINA_BASE_2=</code><code>/usr/local/tomcat2</code> </td> 
 </tr> 
 </tbody> 
</table>

3，重载profile文件

<table> 
 <tbody> 
 <tr> 
 <td> 1 </td> 
 <td> <code>source</code>&nbsp;<code>/etc/profile</code> </td> 
 </tr> 
 </tbody> 
</table>

\[root@tomcat webapps\]\# echo $TOMCAT\_HOME  
/usr/local/tomcat

\[root@tomcat webapps\]\# echo $TOMCAT\_HOME\_2  
/usr/local/tomcat2

4，修改tomcat 配置文件

vim /usr/local/tomcat2/bin/catalina.sh

:%s/CATALINA\_HOME/CATALINA\_HOME\_2/g

39 次替换，共 33 行

notice：部署了vm还得在此文件中将vm的18999改成19999

5，修改conf里面的server.xml

<Connector port="8180" protocol="HTTP/1.1"

<Connector port="8109" protocol="AJP/1.3"
