tomcat多实例部署

java不同于php,单个站点更新维护都会影响到其他站点，一般都会将几个站点放在一个实例下。今天全称演示单台服务器如何配置多个tomcat实例。

环境

tomcat：/usr/local/tomcat-7.0.50
a.ttlsa.com
站点程序：/data/site/a.ttlsa.com
端口：8080

b.ttlsa.com
站点程序：/data/site/b.ttlsa.com
端口：8081

1. tomcat安装

安装很简单，配置好jdk与解压tomcat即可，关于《tomcat安装》我这边不再重复了。

如果连接失效，请复制http://www.ttlsa.com/web/install-tomcat7-on-linux/

2. 配置多实例目录

在tomcat安装目录下创建a.ttlsa.com、b.ttlsa.com，并且将conf、logs、webapp、temp、work目录拷贝到这两个目录，然后tomcat安装目录只需要留下bin、a.ttlsa.com、b.ttlsa.com、lib这4个目录即可。配置后的目录结构如下：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18

# pwd / usr / local / tomcat - 7.0.50 # tree -d -L 2 ├── bin ├── a . ttlsa . com │ ├── conf │ ├── logs │ ├── target │ ├── temp │ ├── webapp │ └── work ├── lib └── b . ttlsa . com ├── conf ├── logs ├── temp ├── webapp └── work

3. 配置站点server.xml

3.1 配置a.ttlsa.com

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

# vim /usr/local/tomcat-7.0.50/a.ttlsa.com/conf/server.xml //注释ajp < ! -- < Connector port = "8009" protocol = "AJP/1.3" redirectPort = "8443" / > -- >   //server端口8005改为8001 < Server port = "8001" shutdown = "SHUTDOWN" >   //在<Engine name="Catalina" defaultHost="localhost">增加host配置，如下 < Host name = "a.ttlsa.com" appBase = "/data/site/a.ttlsa.com"       unpackWARs = "true" autoDeploy = "true"       xmlValidation = "false" xmlNamespaceAware = "false" >       < Context path = "" docBase = ""  reloadable = "true" >         < valve className = "org.apache.catalina.valves.RemoteAddrValve" / >       < / Context > < / Host >

 

3.2 配置b.ttlsa.com

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

# vim /usr/local/tomcat-7.0.50/a.ttlsa.com/conf/server.xml //注释ajp < ! -- < Connector port = "8009" protocol = "AJP/1.3" redirectPort = "8443" / > -- >   //server端口8005改为8002 < Server port = "8002" shutdown = "SHUTDOWN" >   //在<Engine name="Catalina" defaultHost="localhost">增加host配置，如下 < Host name = "b.ttlsa.com" appBase = "/data/site/b.ttlsa.com"       unpackWARs = "true" autoDeploy = "true"       xmlValidation = "false" xmlNamespaceAware = "false" >       < Context path = "" docBase = ""  reloadable = "true" >         < valve className = "org.apache.catalina.valves.RemoteAddrValve" / >       < / Context > < / Host >

4. 多实例启动脚本

在a.ttlsa.com、b.ttlsa.com目录下分别创建启动脚本tomcat.sh
4.1 脚本内容tomcat.sh

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32

#!/bin/sh # AuthName：凉白开 # Website：http://www.ttlsa.com # DateTime：2014-05-04 # description: 启动tomcat多实例. . / etc / init . d / functions RETVAL = $ ? # tomcat实例目录 export CATALINA_BASE = "$PWD" # tomcat安装目录 export CATALINA_HOME = "/usr/local/tomcat-7.0.50" # 可选 export JVM_OPTIONS = "-Xms128m -Xmx1024m -XX:PermSize=128m -XX:MaxPermSize=512m" case "$1" in start ) if [ - f $ CATALINA_HOME / bin / startup . sh ] ; then echo $ "Start Tomcat" $ CATALINA_HOME / bin / startup . sh fi ; ; stop ) if [ - f $ CATALINA_HOME / bin / shutdown . sh ] ; then echo $ "Stop Tomcat" $ CATALINA_HOME / bin / shutdown . sh fi ; ; * ) echo $ "Usage: $0 {start|stop}" exit 1 ; ; esac exit $ RETVAL

4.2 启动脚本赋权限

1	# chmod a+x tomcat.sh

5. 启动测试

5.1 启动/关闭a.ttlsa.com

1 2 3 4 5 6

启动 # cd /usr/local/tomcat-7.0.50/a.ttlsa.com/ # ./tomcat.sh start 关闭 # cd /usr/local/tomcat-7.0.50/a.ttlsa.com/ # ./tomcat.sh stop

5.2 启动/关闭b.ttlsa.com

1 2 3 4 5 6

启动 # cd /usr/local/tomcat-7.0.50/a.ttlsa.com/ # ./tomcat.sh start 关闭 # cd /usr/local/tomcat-7.0.50/a.ttlsa.com/ # ./tomcat.sh stop

备注：一定需要cd到tomcat.sh的当前目录下执行才可以

6. 结束

配置到此结束，如果需要操作多个实例显得比较麻烦，大家可以自行写统一的脚本，我这边有自己的一份，有需要的可以找我要。内容比较多，就不贴出来了。
