tomcat 自启动脚本（守护模式）

tomcat以daemon模式启动

跳转到最新脚本

1.jsvc简介

Jsvc 是专为 Java 应用程序开发的一个工具包，其目标是把 Java 应用程序的普通运行转换为可以配置某个普通用户以 Unix 守护进程即daemon模式运行。这样的话，可以很方便地启动 / 停止应用程序，同时也可以支持开机自启，这样每次重启后，不需要手动重启tomcat就可以自动恢复服务。

生产中daemon守护进程的好处有以下三点

• 以daemon方式运行tomcat可使tomcat不受终端影响，不会因为退出终端而停止运行。
• 可以让tomcat以普通用户身份运行。
• 可以让tomcat在系统启动时自动运行。

2.安装jsvc

Tomcat 安装包的 bin 子目录下就包含了 Jsvc 工具包的源码。

1、将tomcat和jdk安装包上传到服务器。

上传apache-tomcat-9.0.46.tar.gz和jdk-8u181-linux-x64.tar.gz到/tomcat目录下

2、解压缩tomcat和jdk的tar包

假设jdk8的安装目录是 /tomcat/java_home/,Tomcat的安装目录是/tomcat/catalina_home/

tar zxvf /tomcat/apache-tomcat-9.0.46.tar.gz –C /tomcat/catalina_home/

tar zxvf /tomcat/jdk-8u181-linux-x64.tar.gz –C /tomcat/java_home/

3、解压jsvc安装包commons-daemon-native.tar.gz

cd /tomcat/apache-tomcat-9.0.46/bin

tar xzvf commons-daemon-native.tar.gz

4、编译安装jsvc，如果没有配置java环境需要使用参数--with-java指出jdk安装位置

cd commons-daemon-1.1.0-native-src/unix/

./configure --with-java=/tomcat/catalina_home/jdk1.8.0_181

make

5、将解压的jsvc复制到tomcat的bin/目录下

cp jsvc ../../ 

3.使用deamon.sh模式

Tomcat的bin/目录下有个deamon.sh脚本，可以调用deamon.sh start和deamon stop启动/关闭tomcat的守护模式

---

Tomcat8 守护模式开机自启动。

1. cd /etc/init.d

2. vi tomcat8 粘帖一下文本

*)    echo "Usage: $prog {start|stop|restart}"     ;;esacexit 0

3. 保存退出、chmod 755 tomcat8 赋权限

4. 启动 service tomcat8 start

5. chkconfig tomcat8 on，chkconfig --list tomcat 查看启动状态
