linux开机 自动挂载和启动jar包

一、 自动挂载和启动jar包

1、开机配置文件增加命令

vi /etc/rc.local

增加 sh  /home/startup.sh（需要启动的脚本）

2、startup.sh

#!/bin/sh
# 获取当前脚本所在路径
dir=$(cd `dirname $0`; pwd)
jar_name="test.jar"
conf_file="mount.conf"
file_path=${dir}/${conf_file}
log_file=${dir}/"startup.log";
# 加载环境配置
source /etc/profile
source ~/.bash_profile
java_path=${JAVA_HOME}

sudo echo -e "\n" runtime: `date '+%Y-%m-%d %H:%M:%S'` "\n" >> ${log_file}

if [[ ! -f ${dir}/${conf_file} ]];then
    echo -e "\033[31m ${dir}/${conf_file} does not exist! \033[0m" 
    echo -e "${dir}/${conf_file} does not exist! " >> ${log_file}
    exit 1
fi
# 挂载
# sed 过滤'#'开头的；while read -a line 逐行读取， $line第一列， ${line[1]}第二列
sed -e '/^#/d' ${file_path} | more | while read -a line || [ -n "$line" ]; do 
  # -n 不为空，-a 且
  if [ -n "$line" -a -n "${line[1]}" ]; then 
    echo mount "$line ${line[1]}" >> ${log_file}; 
    mount "$line" "${line[1]}";
  fi
done;

# 启动jar
cd ${dir}echo -e "\033[36m now start jar... \033[0m" 
pid=$(pgrep -f ${msg_jar})
if [[ -n $pid ]];then
    kill -9 $pid
fi
# nohup 程序不挂起
nohup ${java_path}/bin/java -jar ${dir}/${msg_jar} &
sleep 10
pid=$(pgrep -f ${msg_jar})
if [[ -z $pid ]];then
    echo -e "\033[31m start ${dir}/${msg_jar} occured error, please read ${jar_name} log.\033[0m" 
    echo -e "start ${dir}/${msg_jar} occured error, please read ${jar_name} log." >> ${log_file}
    exit 1
else
    echo -e "\033[36m start ${dir}/${msg_jar} successful, pid is $pid .\033[0m" 
    echo -e "start ${dir}/${msg_jar} successful, pid is $pid ." >> ${log_file}
fi

二、sudo 执行命令，获取不到环境配置

1、sudo visudo

修改 Defaults env_reset 为 Defaults !env_reset，不让sudo重置环境变量

2、sudo vi ~/.bashrc

增加 alias sudo=sudo PATH=$PATH

执行 source ~/.bashrc 生效

3、sudo java -version或者 java -jar 就能通过sudo执行。
