# 方式一  /etc/rc.d/rc.local #

往 /etc/rc.d/rc.local 追加内容，

先配置java, 环境变量，再启动

以便tomcat开机启动

#cd /etc
    #FILE_NAME=/etc/rc.d/rc.local
    #ubuntu 44
    FILE_NAME=/etc/rc.local
    chmod 775 $FILE_NAME
    echo -e "export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64/" >> $FILE_NAME
    echo -e "export PATH=$""PATH:$""JAVA_HOME/bin" >> $FILE_NAME
    echo -e "/usr/email/start.sh" >> $FILE_NAME

脚本为

# 方式二，systemd #

照着下面的格式创建一个脚本，

添加权限

chmod +x /usr/email/email.service

加软链接

sudo ln -s /usr/email/email.service /etc/systemd/system/multi-user.target.wants/email.service

把脚本，的软连接，加入这个目录后，就会开机自启动
