创build脚本以启动/停止/重新启动服务的良好实践？

我想知道创build一个好的脚本来启动/停止/重启一些服务是一个很好的实践。 我会尽量让自己更清楚，好吗？ 现在，我做这样的事情：假设我想创build一个脚本来start/stop/restart一个服务，所以我创build一个文件夹/company/service name/然后把start.sh和stop.sh ，这是这样的：

start.sh

 #!/bin/bash #VARIABLES SERVICE_NAME="<service name>" USERDEPLOYER="<service name>_deployer" FOLDER=/company/<service name>/ KEYWORD="<keyword>" # #CHECKING SYSTEM STATUS PROC=`ps -ef | grep $SERVICE_NAME | grep $KEYWORD | grep -v grep | awk -F" " '{ print $2 }'`; if [ $PROC ]; then echo "$SERVICE_NAME is running!" echo "Stop then first!" exit fi ### # #STARTING if [[ `/usr/bin/whoami` == $USERDEPLOYER ]] then pushd . echo " " echo "Starting $SERVICE_NAME..." echo "cd $FOLDER" cd $FOLDER #COMMAND <command to start the service> & sleep 20 PROC=`ps -ef | grep $SERVICE_NAME | grep $KEYWORD | grep -v grep | awk -F" " '{ print $2 }'`; if [ -n "$PROC" ] && [ "$PROC" != "" ] then echo "OK: system started." else echo "ERROR: system process not found!" fi echo "script execution finished!" popd else echo "User must be $USERDEPLOYER !" fi 

stop.sh

 #!/bin/bash #VARIABLES SERVICE_NAME="<service name>" USERDEPLOYER="<service name>_deployer" KEYWORD="python" if [[ `/usr/bin/whoami` == $USERDEPLOYER ]] then pushd . echo "Stopping $SERVICE_NAME......" #KILLING PROCESS processPID=`ps -ef | grep $SERVICE_NAME | grep $KEYWORD | grep -v grep | awk -F" " '{ print $2 }'` echo "Trying to kill process with key $SERVICE_NAME - ignore error messages below." kill $processPID sleep 10 while [ -n "$processPID" ] do echo "Waiting process ($processPID) to shutdown...20s" sleep 20 processPID=`ps -ef | grep $SERVICE_NAME | grep $KEYWORD | grep -v grep | awk -F" " '{ print $2 }'` done echo "Ensured process with key $SERVICE_NAME is no longer running." popd else echo "User must be $USERDEPLOYER !" fi 

之后，我创build一个用户service name_deployer ，而不是给这个文件夹的所有权，这些scrits， start.sh和stop.sh ，给予read, write and execute的权限。

• Powershell脚本插入带有撇号错误的SQL语句
• 本地login脚本删除当前login用户的文件夹
• 哪些工具可以在多个Windows服务器上运行脚本？
• ＃！ 不会让linux运行一个解释器
• 似乎无法得到expr substr工作

然后在/etc/init.d/创build以下脚本作为service name-service ：

 #!/bin/bash # # Linux chkconfig stuff: # # chkconfig: 2345 56 10 # 2345 56 # 2345 10 # description: <description> # Source function library. SERVICE_NAME="<service name>-service" SERVICE_USER="<service name>_deployer" FOLDER="/company/<service name>/" start() { if [[ `/usr/bin/whoami` == $SERVICE_USER ]] then cd $FOLDER ./start.sh #NOT USER _root else cd $FOLDER su $SERVICE_USER ./start.sh fi } stop() { cd $FOLDER su $SERVICE_USER ./stop.sh } #Body main case "$1" in start) start ;; stop) stop ;; restart) echo "Restarting $SERVICE_NAME..." echo " " stop sleep 10 start ;; *) echo $"Usage: $0 {start|stop|restart}" exit 1 esac exit 0 

给定所有权为service name_deployer以及read, write and execute.的权限read, write and execute.

然后将服务添加到服务列表中，如下所示：/ sbin / chkconfig –add service name-service （suse和其他）或update-rc.d service name-service默认值（ubuntu）

就这样！ 你们认为这是一个好方法吗？ 我只是问，因为我想为这种脚本和程序创build一个很好的标准。 对不起，如果你们认为这是一个蹩脚的问题，但对我来说是非常重要的这种程序。

感谢你们！
