Windows如何設(shè)置定時(shí)重啟Tomcat

更新時(shí)間：2024年01月02日 15:16:06 作者：謝小濤

本文主要介紹了Windows如何設(shè)置定時(shí)重啟Tomcat,可以使用Windows系統(tǒng)的計(jì)劃任務(wù)程序,在這里設(shè)置定時(shí)執(zhí)行的.bat批處理文件,具有一定的參考價(jià)值,感興趣的可以了解一下

項(xiàng)目場景：

系統(tǒng)：Windows 7

Tomcat：apache-tomcat-8.0.5

JDK：1.8

問題描述

最近項(xiàng)目的Tomcat隔一段時(shí)間就假死，最后想到的解決方式就是：每天凌晨1點(diǎn)重啟tomact。

解決方案：

使用Windows系統(tǒng)的計(jì)劃任務(wù)程序，可以在這里設(shè)置定時(shí)執(zhí)行的.bat批處理文件（將你要定時(shí)執(zhí)行的cmd命令放在這里）,這樣就可以實(shí)現(xiàn)讓電腦在某個(gè)時(shí)刻做你想讓它干的事。

實(shí)現(xiàn)步驟：

一、創(chuàng)建tomcat重啟的腳本

創(chuàng)建txt文件restart.txt，編輯內(nèi)容，把下面的內(nèi)容復(fù)制進(jìn)去，然后把綴改為.bat，最后文件名為：restart.bat

echo 正在關(guān)閉Tomcat服務(wù)，請(qǐng)稍等......

echo 啟動(dòng)Tomcat服務(wù)完成

把restart.bat 文件復(fù)制到apache-tomcat-8.0.50\bin目錄下，然后可以直接雙擊運(yùn)行，啟動(dòng)會(huì)報(bào)個(gè)錯(cuò)，是因?yàn)閠omcat沒啟動(dòng)，是正常的。

二、創(chuàng)建任務(wù)計(jì)劃程序

1、開始菜單搜索“任務(wù)計(jì)劃程序”

或者到控制面板里面找到“計(jì)劃任務(wù)”

2、彈出任務(wù)計(jì)劃程序界面，在右側(cè)點(diǎn)擊創(chuàng)建任務(wù)

3、輸入名稱和描述

4、點(diǎn)擊觸發(fā)器選項(xiàng)卡，點(diǎn)擊左下角新建，彈出新建操作，新建一個(gè)觸發(fā)器，每天凌晨一點(diǎn)觸發(fā)

5、點(diǎn)擊操作選項(xiàng)卡，點(diǎn)擊左下角新建，彈出新建操作，點(diǎn)擊瀏覽。選擇要執(zhí)行的腳本restart.bat ，點(diǎn)擊打開確定。

附加：

這里說下nginx配置集群和tomcat實(shí)現(xiàn)session共享

首先要啟動(dòng)兩個(gè)tomcat，然后端口不一樣，比如8889和8899

1、nginx.conf關(guān)鍵配置

upstream serverlist {
   #最少連接數(shù)，根據(jù)連接數(shù)多少自動(dòng)選擇后端服務(wù)器，連接數(shù)相等時(shí)根據(jù)權(quán)重選擇
   least_conn;
   #每個(gè)請(qǐng)求按訪問ip的hash結(jié)果分配，這樣每個(gè)訪客固定訪問一個(gè)后端服務(wù)器，可以解決session的問題
   #ip_hash; 
   #若120秒內(nèi)出現(xiàn)2次錯(cuò)誤，則下個(gè)120秒內(nèi)不再訪問此服務(wù)器，weight權(quán)重越大，請(qǐng)求機(jī)會(huì)越多
   server 127.0.0.1:8889 max_fails=2 fail_timeout=120s weight=1;#主服務(wù)
   server 127.0.0.1:8899 max_fails=2 fail_timeout=120s weight=1 backup;#備用tomcat服務(wù)，主服務(wù)掛了會(huì)調(diào)用備用服務(wù)
}

2、tomcat實(shí)現(xiàn)session共享

server.xml在Engine標(biāo)簽內(nèi)加上配置

<Engine name="Catalina" defaultHost="localhost">
    <!-- tomcat集群session共享 -->
    <Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster"/>
</Engine>

修改web項(xiàng)目，工程WEB-INF下的web.xml，添加如下一句配置
