tomcat自动部署脚本+tomcat假死和异常

一个简单的tomcat自动化部署脚本 ，实现功能：

（1） 检查tomcat进程是否存在，如果存在则kill掉

（2） 备份现有war包到tomcat/backup目录

（3） 复制当前目录新war包到tomcat/webapps目录

（4） 启动tomcat

#!/bin/bash
now=`date +%Y%m%d%H%M%S`
tomcatPath=/home/tomcat/software/tomcat6
backupPath=/home/tomcat/software/tomcat6/backup
war=$1

if [ -e "$war.war" ]; then
  echo -e "\033[34m war archive: $war.war \033[0m"
else 
  echo -e "\033[31m war archive '$war.war' not exists \033[0m"
  exit -1
fi
# change color
echo -e "\033[34m"
#create backup dir
if [ ! -d "$backupPath" ]; then
  mkdir "$backupPath"
fi
echo "tomcat home: $tomcatPath"
echo "backup path: $backupPath"
echo 'try to stop tomcat...'

pid=`ps aux|grep "java"|grep "$tomcatPath"|awk '{printf $2}'`
if [ -n $pid ]; then
  echo "tomcat pid: $pid";
  kill -9 $pid;
fi

echo 'stop tomcat finished...'
echo 'backup old archive...'
if [ -f "$tomcatPath/webapps/$war.war" ]; then
  mv -v "$tomcatPath/webapps/$war.war" "$backupPath/$1_$now.war";
fi

rm -rf $tomcatPath/webapps/$war*
echo "copy $war.war archive to webapps.."
cp -v "$war.war" "$tomcatPath/webapps/"

echo -e "\033[32m"
echo 'startup tomcat...'

sh $tomcatPath/bin/startup.sh

tail -10f $tomcatPath/logs/catalina.out

使用时，需要先修改tomcatPath的值为实际tomcat路径。

保存该文件到autodeploy.sh， 执行命令:

2：看服务是不是假死状态

（1）第一种写法：

#!/bin/bash
# define url
export LANG=zh_CN.UTF8  
CURRENT_DATE="`date +%Y-%m-%d`"
TEMPFILEPATH=/home/ServiceCheck
# check url
cat $TEMPFILEPATH/urls.txt | while read url
do
    ALIVE=$(curl -o /dev/null -s -w %{http_code} ${url})
    if [ "$ALIVE" != "200" ]; then
            echo "'${url}' 网站无法访问,请检查" | mail -s "网站tomcat服务监控 ${url}" 
    else
        echo "网站tomcat服务监控  tomcat服务监控'${url}' is OK !"
    fi
done

（2）第二种写法
