tomcat多server配置实例

前言
通过tomcat多server配置，实现一台机器启动多个tomcat服务并监听不同端口。实现各server单独启停、war包统一管理、端口分离、配置文件分离、日志分离。
一、tomcat目录规划
其中粗体为文件夹，红色为需要修改的重要配置文件
一级目录
二级目录
说明
三级目录
四级conf下配置文件
tomcat
apache-tomcat-9.0.60
tomcat源文件所在目录
    
app
war包存放位置
project1_name.war
project2_name.war
  
app_soft
依赖包存放位置
    
java
java环境存放位置
    
server1
server1
conf
logs
temp
tomcat.pid
webapps
work
Catalina
catalina.policy
catalina.properties
context.xml
logging.properties
server.xml
tomcat-users.xml
tomcat-users.xsd
web.xml
server2
server2
    
server3
server3
    
tomcat.keysore
安全要求，密钥文件
    
tomcat.sh
启动脚本
    
二、创建目录及配置文件
cd /data/tomcat
mkdir app server1 server2 server3
touch tomcat.sh
#给脚本文件加上可执行权限
chmod +x tomcat.sh
cp -r conf server1
cd server1
mkdir logs temp webapps work
touch tomcat.pid
三、配置文件修改
1、修改Catalina配置文件
该配置涉及启动路径，修改后可多server从同一文件夹读取war包启动
#进入配置所在目录
cd /data/tomcat/server1/conf/Catalina
#改名
mv localhost server1
cd server1
#编辑工程名.xml文件
vi project1_name.xml
#添加启动路径
<?xml version="1.0" encoding="UTF-8"?>
<Context antiJARLocking="true" docBase="/data/tomcat/app/project1_name.war" path="/enodeb-fault"/>
2、修改server.xml配置文件
该配置涉及监听端口号
vi /data/tomcat/server1/conf/server.xml
#可用该命令查看现有配置
perl -lne 'print unless (/<!--/../-->/)' server.xml
配置文件如下，一般分配与server编号一致的端口号避免端口冲突，以server2为例
其中2、21、23、27、35行为修改的部分
 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <Server port="8002" shutdown="SHUTDOWN">
 3   <Listener className="org.apache.catalina.startup.VersionLoggerListener" />
 4   <Listener className="org.apache.catalina.core.AprLifecycleListener" SSLEngine="on" />
 5   <Listener className="org.apache.catalina.core.JreMemoryLeakPreventionListener" />
 6   <Listener className="org.apache.catalina.mbeans.GlobalResourcesLifecycleListener" />
 7   <Listener className="org.apache.catalina.core.ThreadLocalLeakPreventionListener" />
 8 
 9   <GlobalNamingResources>
10     <Resource name="UserDatabase" auth="Container"
11               type="org.apache.catalina.UserDatabase"
12               description="User database that can be updated and saved"
13               factory="org.apache.catalina.users.MemoryUserDatabaseFactory"
14               pathname="conf/tomcat-users.xml" />
15   </GlobalNamingResources>
16 
17   <Service name="Catalina">
18 
19 
20 
21     <Connector port="8082" protocol="HTTP/1.1"
22                connectionTimeout="20000"
23                redirectPort="8442" />
24 
25 
26 
27     <Engine name="Catalina" defaultHost="server2">
28 
29 
30       <Realm className="org.apache.catalina.realm.LockOutRealm">
31         <Realm className="org.apache.catalina.realm.UserDatabaseRealm"
32                resourceName="UserDatabase"/>
33       </Realm>
34 
35       <Host name="server2"  appBase="webapps"
36             unpackWARs="true" autoDeploy="true">
37 
38 
39         <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
40                prefix="localhost_access_log" suffix=".txt"
41                pattern="%h %l %u %t &quot;%r&quot; %s %b" />
42 
43       </Host>
44     </Engine>
45   </Service>
46 </Server>
server.xml
3、修改context.xml配置文件
该配置涉及数据源配置，由于该实例不涉及，略
四、启动脚本编写
启动脚本如下：
  1 #!/bin/sh
  2 ## ./tomcat.sh serverX restart 重启
  3 ## ./tomcat.sh serverX start   启动
  4 ## ./tomcat.sh serverX stop    停止
  5 
  6 #tomcat 目录
  7 export SERVER_ID=$1
  8 export CATALINA_HOME="/data/tomcat"
  9 export CATALINA_BASE="/data/tomcat/$SERVER_ID"
 10 export CATALINA_TMPDIR="$CATALINA_BASE/temp"
 11 export CATALINA_PID="$CATALINA_BASE/tomcat.pid"
 12 
 13 #变量
 14 USER=`whoami`
 15 
 16

 18 if [ $USER == "cnms_user" ];then
 19

 23 
 24        else
 25            echo "$CATALINA_BASE不存在"
 26            exit
 27        fi
 28   elif [ $1 == "server2" ];then

 31        else
 32            echo "$CATALINA_BASE不存在"

 40            exit

五、配置环境变量快捷启动
vi $HOME/.bashrc
#添加如下内容
alias tstart='tomcat_start() { /data/tomcat/tomcat.sh $1 start;};tomcat_start'
alias tstop='tomcat_stop() { /data/tomcat/tomcat.sh $1 stop;};tomcat_stop'
alias trestart='tomcat_restart() { /data/tomcat/tomcat.sh $1 restart;};tomcat_restart'
#立即生效
source $HOME/.bashrc
