tomcat脚本:
原始脚本:
[[email protected] scripts]# cat Tomcat-init #!/bin/bash ### BEGIN INIT INFO # Provides: tomcat # Required-Start: $remote_fs $syslog # Required-Stop: $remote_fs $syslog # Default-Start: 2 3 4 5 # Default-Stop: 0 1 6 # Short-Description: tomcat-server daemon # Description: tomcat-server daemon ### END INIT INFO # # chkconfig: - 95 15 # description: Tomcat start/stop/status script #Location of JAVA_HOME (bin files) export JAVA_HOME= #Add Java binary files to PATH export PATH=$JAVA_HOME/bin:$PATH #CATALINA_HOME is the location of the configuration files of this instance of Tomcat CATALINA_HOME=/usr/local/tomcat #TOMCAT_USER is the default user of tomcat TOMCAT_USER=www #TOMCAT_USAGE is the message if this script is called without any options TOMCAT_USAGE="Usage: $0 {e[00;32mstarte[00m|e[00;31mstope[00m|e[00;32mstatuse[00m|e[00;31mrestarte[00m}" #SHUTDOWN_WAIT is wait time in seconds for java proccess to stop SHUTDOWN_WAIT=20 tomcat_pid() { echo `ps -ef | grep $CATALINA_HOME/ | grep -v grep | tr -s " "|cut -d" " -f2` } start() { pid=$(tomcat_pid) if [ -n "$pid" ]; then echo -e "e[00;31mTomcat is already running (pid: $pid)e[00m" else echo -e "e[00;32mStarting tomcate[00m" if [ `user_exists $TOMCAT_USER` = "1" ]; then su $TOMCAT_USER -c $CATALINA_HOME/bin/startup.sh else $CATALINA_HOME/bin/startup.sh fi status fi return 0 } status() { pid=$(tomcat_pid) if [ -n "$pid" ]; then echo -e "e[00;32mTomcat is running with pid: $pide[00m" else echo -e "e[00;31mTomcat is not runninge[00m" fi } stop() { pid=$(tomcat_pid) if [ -n "$pid" ]; then echo -e "e[00;31mStoping Tomcate[00m" $CATALINA_HOME/bin/shutdown.sh let kwait=$SHUTDOWN_WAIT count=0; until [ `ps -p $pid | grep -c $pid` = '0' ] || [ $count -gt $kwait ] do echo -n -e "e[00;31mwaiting for processes to exite[00m "; sleep 1 let count=$count+1; done if [ $count -gt $kwait ]; then echo -n -e " e[00;31mkilling processes which didn't stop after $SHUTDOWN_WAIT secondse[00m" kill -9 $pid fi else echo -e "e[00;31mTomcat is not runninge[00m" fi return 0 } user_exists() { if id -u $1 >/dev/null 2>&1; then echo "1" else echo "0" fi } case $1 in start) start ;; stop) stop ;; restart) stop start ;; status) status ;; *) echo -e $TOMCAT_USAGE ;; esac exit 0 [[email protected] scripts]#
tomcat启动的时候看不出异常,关闭的时候回报错类似:
SEVERE: Could not contact localhost:8005. Tomcat may not be running.
即为8005端口未运行,使用命令netstat -ant 发现 没有找到8005端口
[[email protected] scripts]# netstat -lntup|grep java tcp 0 0 :::8009 :::* LISTEN 10373/java tcp 0 0 :::8080 :::* LISTEN 10373/java
解决办法:
修改$JAVA_HOME/jre/lib/security/Java.security 文件中 securerandom.source 配置项:
将 securerandom.source=file:/dev/random 修改为: securerandom.source=file:/dev/urandom(网上查询的结果,我改完这个就可以了,下面的未测试) 如果,仍然不生效,则修改为: file:/dev/./urandom
实战如下:
[[email protected] scripts]# vim /usr/java/jdk/jre/lib/security/java.security securerandom.source=file:/dev/random 修改为 securerandom.source=file:/dev/urandom
再次启动tomcat就有8005端口了
[[email protected] scripts]# netstat -lntup|grep java tcp 0 0 ::ffff:127.0.0.1:8005 :::* LISTEN 10615/java tcp 0 0 :::8009 :::* LISTEN 10615/java tcp 0 0 :::8080 :::* LISTEN 10615/java
最后脚本被修改为:
验证脚本:
脚本在root下面可以正常运行,在设置的普通账号可以运行,但是在非设置非root提示没有权限。
