# usage 1:
|

# sh deploy.sh start /usr/local/tank/single-boot/single-boot-1.0.jar
|
||
|
||
# EN:start starts the server, the absolute path is very important,[/usr/local/tank/single-boot/single-boot-1.0.jar] is the absolute path of the jar package，
|
||

||
# CN:start启动服务器，绝对路径很重要，[/usr/local/tank/single-boot/single-boot-1.0.jar]是jar包的绝对路径

# usage 2:
|
||
# sh deploy.sh stop single
|

|
||
# EN:stop closes the server, use command jps | grep single，grab the java process that needs to be closed, so you don't need to enter the full name of single-boot
|
||
# If you have two launchers named [single-boot1.jar], [single-boot2], both will be turned off
|
||
|
||
# CN:stop关闭服务器，会使用jps | grep single，抓取需要关闭的java进程，所以不需要输入single-boot的全名（不是绝对路径）
|
||
# 如果你有两个名称为[single-boot1.jar]，[single-boot2]的启动程序，则会把这两个都关闭

# usage 3:
|
||
# sh deploy.sh update /usr/local/tank/single-boot/single-boot-1.0.jar
|
||
|
||
# EN:update updates the jar package. By default, the jar package under the root path [single-boot-1.0.jar] will be
|
||
# used to update the jar package of [/usr/local/tank/single-boot/single-boot-1.0.jar]
|
||
# In this way, the jar must be placed in the root directory (the topmost directory, not the root directory, don't make a mistake),
|
||
# it is very important, because the jar of the root path is used by default to update the jar at the location you specify
|
||
|
||
# CN:update更新jar包，默认会使用根路径[/single-boot-1.0.jar]下的jar包去更新[/usr/local/tank/single-boot/single-boot-1.0.jar]的jar包
|
||
# 此种方式jar必须放在 / 根目录(最上层的目录，不是root目录，不要弄错了)，非常重要，因为默认使用根路径的jar取更新你指定位置的jar

# usage 4:

# sh deploy.sh stopUpdateStart /usr/local/tank/single-boot/single-boot-1.0.jar

# EN:stop Update Start, execute the commands stop, update, start, three-in-one commands in order,
|
||
# because there is an update, so you must put your jar in the root directory
|
||
|
||
# CN:stopUpdateStart，按顺序执行命令stop，update，start，三合一的命令，因为有个update，所以必须把你的jar放在根目录（非常重要）
|
||
# stop的是[single-boot-1.0.jar]，会分割字符串[/usr/local/tank/single-boot/single-boot-1.0.jar]获取到最后的分号后的名称
|

# update的是[/usr/local/tank/single-boot/single-boot-1.0.jar]，所以必须把jar放在 / 根目录(最上层的目录，不是root目录，不要弄错了)，非常重要
