j**a環境變數還是原來的配置
把以前的tomcat刪除
tar xf apache-tomcat-8.5.40.tar.gz -c /usr/local/
mkdir -p /usr/local/tomcat_instance/tomcat1
mkdir -p /usr/local/tomcat_instance/tomcat2
cp -r /usr/local/apache-tomcat-8.5.40/conf/ /usr/local/tomcat_instance/tomcat1
cp -r /usr/local/apache-tomcat-8.5.40/conf/ /usr/local/tomcat_instance/tomcat2
mkdir /usr/local/tomcat_instance//bin
touch /usr/local/tomcat_instance/tomcat1/bin/startup.sh
chmod +x /usr/local/tomcat_instance/tomcat1/bin/startup.sh
touch /usr/local/tomcat_instance/tomcat2/bin/startup.sh
chmod +x /usr/local/tomcat_instance/tomcat2/bin/startup.sh
[root@localhost ~]# vim /usr/local/tomcat_instance/tomcat1/bin/startup.sh
#!/bin/bash
export catalina_home="/usr/local/apache-tomcat-8.5.40"
export catalina_base="/usr/local/tomcat_instance/tomcat1"
export catalina_tmpdir="$catalina_base/temp"
export catalina_pid="$catalina_base/bin/tomcat.pid"
export j**a_opts="-server -xms1024m -xmx1024m -dj**a.awt.headless=ture -dtomcat.name=tomcat1"
#建立logs目錄
if [ ! -d "$catalina_base/logs" ];then
mkdir $catalina_base/logs
fi#建立temp目錄
if [ ! -d "$catalina_base/temp" ];then
mkdir $catalina_base/temp
fi#呼叫tomcat啟動指令碼
bash $catalina_home/bin/startup.sh "$@"
[root@localhost ~]# vim /usr/local/tomcat_instance/tomcat2/bin/startup.sh
#!/bin/bash
export catalina_home="/usr/local/apache-tomcat-8.5.40"
export catalina_base="/usr/local/tomcat_instance/tomcat2"
export catalina_tmpdir="$catalina_base/temp"
export catalina_pid="$catalina_base/bin/tomcat.pid"
export j**a_opts="-server -xms1024m -xmx1024m -dj**a.awt.headless=ture -dtomcat.name=tomcat2"
#建立logs目錄
if [ ! -d "$catalina_base/logs" ];then
mkdir $catalina_base/logs
fi#建立temp目錄
if [ ! -d "$catalina_base/temp" ];then
mkdir $catalina_base/temp
fi#呼叫tomcat啟動指令碼
bash $catalina_home/bin/startup.sh "$@"
[root@localhost ~]# vim /usr/local/tomcat_instance/tomcat1/bin/shutdown.sh
export catalina_home="/usr/local/apache-tomcat-8.5.40"
export catalina_base="/usr/local/tomcat_instance/tomcat1"
export catalina_tmpdir="$catalina_base/temp"
export catalina_pid="$catalina_base/bin/tomcat.pid"
bash $catalina_home/bin/shutdonw.sh "$@"
[root@localhost ~]#chmod +x /usr/local/tomcat_instance/tomcat1/bin/shutdown.sh
內容差不多修改個成tomcat2
[root@localhost ~]#chmod +x /usr/local/tomcat_instance/tomcat2/bin/shutdown.sh
[root@localhost ~]# vim /usr/local/tomcat_instance/tomcat2/conf/server.xml
只要tomcat2的埠不與tomcat1的埠衝突即可
檢視是否有兩個pid號不一樣j**a程序
192.168.200.112:8080
192.168.200.112:8090
在做個例項很簡單：
[root@localhost ~]#
[root@localhost ~]# cd /usr/local/tomcat_instance/
[root@localhost tomcat_instance]# cp -r tomcat2 tomcat3
[root@localhost ~]#
[root@localhost tomcat_instance]# vim tomcat3/bin/shutdown.sh
把2全改成3
[root@localhost tomcat_instance]# vim tomcat3/bin/startup.sh
把2全改成3
[root@localhost tomcat_instance]# rm -rf tomcat3/bin/tomcat.pid
[root@localhost ~]#
[root@localhost tomcat_instance]# vim tomcat3/conf/server.xml
該那三個埠號即可：注意不要與tomcat1和tomcat2埠號衝突
把裡面的內容2改成3即可
[root@localhost ~]# /usr/local/tomcat_instance/tomcat3/bin/startup.sh
j**a埠號變成三對
測試即可
測試時找一台nginx機器，修改配置檔案

tomcat單機多例項配置及啟動（linux環境）
也有幾個月沒更新csdn，主要是由於現在的工作環境是封閉式的，禁止外網訪問，還有保密之類的，所以一些在專案上用到的東西來不及記錄上來，現在基本上算是忙過去了，空閒下來整理一下過去幾個月裡用到的東西。關於tomcat的多例項有兩種，多機和單機，一般工作上都是單機多例項配置，我們在配置時也是用的這個，主...
