Ubuntu Setup Redis boot up

Source: http://blog.chinaunix.net/uid-22312037-id-3484071.html

Today, calm down, the end of the Redis boot start regret. For me, this is a work of no small size, if it is to be fully understood. The difficulties are as follows:

1---Redis startup script, and shell script writing.

2---Linux service mechanism, how those processes will boot off.

Indeed, some difficulties have been encountered. Fortunately, today is a good state, all solved. So, the flow records are as follows.

Start the shell script as follows, of course, also refer to others.

#! /bin/sh

server_dir=/opt/redis-2.6.10
server_name=redis-server
demo= $server _dir/src/$server _name
configuration_file= $server _dir/redis.conf
pid_file= $server _dir/pid/redis.pid


start ()
{
  # Detects if the server exists and has execute permissions
  if test-x $demo
    echo "Starting Redis" 
  then
    #执行启动命令, returns the execution result
    if $demo $ Configuration_file 
    then
      echo  "OK"
    else
      echo  "Failed"
    fi
  Else
    Echo "Could not find Redis server ($demo)"
  fi
}

Stop ()
{
  #检测pid文件是否存在, if present, indicates running
  if TEST-E $pid _file
     then echo "Stopping Redis"
    #pid文件中只存储了进程号, so get the process number directly and kill
    if Kill ' cat $pid _file '
    Then
      echo "OK"
    else
      echo "Failed"
    fi
  Else
    echo "No server is running!"
    Exit 0
  Fi
} 

restart ()
{
  stop
  start
}


#检测输入的命令 case $ in 
  start)
    start
    ;;
  Stop)
    stop
    ;;
  restart|reload)
    restart
    ;;
  *)
    echo  "Bad command"
    exit 1
Esac

exit 0

Problems encountered:

Use of 1--shell case

Use of the 2--shell test command

3--shell Space (Assignment/judgment)

If the script passes after the test, you can do the next task: Set the script to start execution.
