linux – 我应该采取哪些措施来保护Tomcat 6.x？

我在/usr/java / tomcat(CATALINA_HOME)下安装了Tomcat应用程序,在/ var / lib / tomcat(CATALINA_BASE)下安装了一个实例：

cd /usr/java
sudo tar xzvf ~/downloads/apache-tomcat-6.0.18.tar.gz
sudo ln -s apache-tomcat-6.0.18 tomcat
sudo /usr/sbin/useradd -d /var/lib/tomcat -c "Apache Tomcat" -m -s /sbin/nologin tomcat
cd /var/lib/tomcat
sudo mkdir logs work temp
sudo chown tomcat:tomcat logs temp work
(cd /usr/java/tomcat && sudo tar cvf - conf webapps) | sudo tar xvf -
sudo chmod -R g+rw webapps conf
sudo chown -R tomcat:tomcat webapps conf
cd webapps/
sudo rm -rf docs examples manager host-manager
cd ../conf
sudo chmod g+r *

然后我构建了jsvc包装器：

cd
tar xzvf downloads/apache-tomcat-6.0.18.tar.gz
tar xzvf apache-tomcat-6.0.18/bin/jsvc.tar.gz
cd jsvc-src
chmod +x configure
./configure --with-java=$JAVA_HOME
make
./jsvc --help
sudo cp jsvc /usr/local/sbin/

最后,我收紧了实例目录的权限：

cd /var/lib/tomcat
sudo chmod -R 0700 conf
sudo chmod -R 0750 logs
sudo chmod -R 0700 temp
sudo chmod -R 0700 work
sudo chmod -R 0770 webapps/
sudo chown -R tomcat:tomcat conf
sudo chown -R tomcat:tomcat logs

现在运行Tomcat时,您需要使用jsvc启动它,因此请将此脚本添加为/etc/init.d/tomcat并对其进行符号链接：

#!/bin/sh
#
# tomcat       Startup script for the Apache Tomcat Server running under jsvc
#
# chkconfig: 345 85 15
# description: Apache Tomcat
# pidfile: /var/run/jsvc.pid
