MySQL，nginx，tomcat檢查進程是否存在以及啟動
#!/bin/bash
if [
netstat -tlunp|grep mysql|wc -l -gt 0 ] #過濾進程名為mysql,轉成數字 then
echo "MySQL is Running."
else
echo "MySQL is Stopped."
/etc/init.d/mysql start

vi nginx_mon.sh
#!/bin/bash
if [ netstat -tlunp|grep nginx|wc -l -gt 0 ] #過濾進程名為nginx,轉成數字
then

vi tomcat_mon.sh
#!/bin/sh
func:自動監控tomcat腳本並且執行重啟操作
獲取tomcat進程ID
TomcatID=$(ps -ef |grep tomcat |grep -w ‘tomcat‘|grep -v ‘grep‘|awk ‘{print $2}‘)
tomcat啟動程序(這裏註意tomcat實際安裝的路徑)
StartTomcat=/usr/local/tomcat/bin/startup.sh
TomcatCache=/usr/local/tomcat/work
定義要監控的頁面地址
WebUrl=http://192.168.254.131:8080/
日誌輸出
GetPageInfo=/tmp/TomcatMonitor.Info
TomcatMonitorLog=/tmp/TomcatMonitor.log
Monitor()
{
echo "[info]開始監控tomcat...[$(date +‘%F %H:%M:%S‘)]"
if [[ $TomcatID ]];then # 這裏判斷TOMCAT進程是否存在
echo "[info]當前tomcat進程ID為:$TomcatID,繼續檢測頁面..."
檢測是否啟動成功(成功的話頁面會返回狀態"200")
TomcatServiceCode=$(curl -s -o $GetPageInfo -m 10 --connect-timeout 10 $WebUrl -w %{http_code})
if [ $TomcatServiceCode -eq 200 ];then
echo "[info]頁面返回碼為$TomcatServiceCode,tomcat啟動成功,測試頁面正常......"
else
echo "[error]tomcat頁面出錯,請註意......狀態碼為$TomcatServiceCode,錯誤日誌已輸出到$GetPageInfo"
echo "[error]頁面訪問出錯,開始重啟tomcat"
kill -9 $TomcatID # 殺掉原tomcat進程
sleep 3
rm -rf $TomcatCache # 清理tomcat緩存
$StartTomcat
fi else
echo "[error]tomcat進程不存在!tomcat開始自動重啟..."
echo "[info]$StartTomcat,請稍候......"
rm -rf $TomcatCache
$StartTomcat
fi
echo "------------------------------"
