一台服务部署多个tomcat注意事项

第一步

添加tomcat环境变量

# vim /etc/profile
加入下代码

# TOMCAT

ATALINA_BASE=/usr/local/tomcat8
CATALINA_HOME=/usr/local/tomcat8
TOMCAT_HOME=/usr/local/tomcat8
export ATALINA_BASE CATALINA_HOME TOMCAT_HOME

修改应用环境变量，是配置生效
# source /etc/profile

第二步

cd /usr/local/tomcat8/conf

vim server.xml
