linux开机自启动方法

服务开机自启

docker 开机自启方法

容器没有自启 执行一下 docker update --restart=always NAMES[容器名称]

java 服务器开机自启方法

第一种：利用 rc.local 文件完成开机自启，vi /etc/rc.local

#!/bin/bash
# THIS FILE IS ADDED FOR COMPATIBILITY PURPOSES
#
# It is highly advisable to create own systemd services or udev rules
# to run scripts during boot instead of using this file.
#
# In contrast to previous versions due to parallel execution during boot
# this script will NOT be run after all other services.
#
# Please note that you must run 'chmod +x /etc/rc.d/rc.local' to ensure
# that this script will be executed during boot.
# 这边键入需要启动的脚本
/home/xxx/xx/xx/auto-restart.sh 

auto-restart.sh 脚本模版

#!/bin/sh
#chkconfig: 2345 80 05

#如果有mysql和redis 或者其他docker容器需要关联重启的可放一起。
#echo "等待Mysql和Redis启动..."
#sleep 90s
#echo "启动nginx"
#/usr/local/nginx/sbin/nginx
#sleep 2s
# java服务路径
cd /xx/xx/xxx-xx/xxx/xx 
echo "启动xxxx服务"
sh rsbc.sh stop
sleep 10s
sh rsbc.sh start
echo "xxxx startup"
tail -f /dev/null
exit $?

rsbc.sh 脚本模版可根据需要进行调整这边给出常见脚本例子

#!/bin/sh

# shell directory
SH_DIR=$(cd "$(dirname "$0")"; pwd)
cd ${SH_DIR}

ACTIVE=$2
ACTIVE=${ACTIVE:=prod}

#[ ! -e "${JAVA_HOME}/bin/java" ]
#export JAVA_HOME
#JAVA="/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.151-5.b12.el7_4.x86_64/bin/java"
JAVA=${JAVA_HOME}/bin/java

第二种：/etc/systemd/system/ 路径下面新建对应的xxx.service

# 开机自启
systemctl enable xxx.service

# 开启服务
systemctl start xxx.service

# 查询服务状态
systemctl status xxx.service

xxx.service例子

[Unit]

ExecStop=/bin/sh /xxx/xx/xx/xx/rsbc.sh stop

以上两种方法看实际业务情况而定用那种。
