我有一个命令,如果我从命令行执行它,它可以正常工作...但是当我将它放在 init.d 脚本中时,它不会启动(嗯..它可以启动,但行为与直接运行时不同)。
知道为什么这在初始化脚本上不起作用吗?
命令是:bluepill load /var/www/html/bluepill.conf
init.d 脚本是:
#!/bin/sh
## Based on http://www.novell.com/coolsolutions/feature/15380.html
# chkconfig: 345 99 1
# processname: solr
# Provides: bluepill
# Default-Start: 3 4 5
# Default-Stop: 0 1 2 6
# Short-Description: bluepill daemon, providing process monitoring
# Description: Bluepill
# Check for missing binaries
BLUEPILL_BIN=/usr/local/bin/bluepill
test -x $BLUEPILL_BIN || { echo "$BLUEPILL_BIN not installed";
if [ "$1" = "stop" ]; then exit 0;
else exit 5; fi; }
# Check for existence of needed config file and read it
BLUEPILL_CONFIG=/var/www/html/bluepill.conf
test -r $BLUEPILL_CONFIG || { echo "$BLUEPILL_CONFIG not existing";
if [ "$1" = "stop" ]; then exit 0;
else exit 6; fi; }
case "$1" in
start)
echo -n "Starting bluepill "
$BLUEPILL_BIN load $BLUEPILL_CONFIG
;;
stop)
echo -n "Shutting down bluepill "
$BLUEPILL_BIN quit
;;
restart)
## Stop the service and regardless of whether it was
## running or not, start it again.
$0 stop
$0 start
;;
*)
## If no parameters are given, print which are avaiable.
echo "Usage: $0 {start|stop|restart}"
exit 1
;;
esac
更新(回答几个问题):
我还添加了脚本以便在启动时执行:
chkconfig --add bluepill_script
chkconfig --level 345 bluepill_script on
答案1
尝试添加
PATH=/sbin:/bin:/usr/sbin:/usr/bin:/usr/local/sbin:/usr/local/bin
到初始化脚本的顶部。
答案2
我将在运行时响应卡米尔 (Kamil) 的输出调用。
此外,您是否尝试过chkconfig --add bluepill
和chkconfig bluepill on
。
否则,我敢打赌它是脚本中的某种环境变量。尝试在开始时通过. /etc/profile
或类似方式获取环境。特别是因为它看起来像是安装在 /usr/local/bin 中。它可能需要正确设置 PATH 或 LD_LIBRARY_PATH。

我正在使用以下 init.d 脚本,并且遇到了类似的问题,因为 bluepill gem 安装在 rvm 安装下。请注意,必须获取 rvm 环境变量,但也可以获取 /etc/profile(因为它也在那里设置)来实现相同的目的。我正在使用 Opscode cookbook 配方来设置这些,因此这些路径被设置为变量,具体取决于 rvm cookbook 安装其 gem 的位置。
#!/bin/bash
#
# Bluepill
#
# chkconfig: - 85 15
# description: start, stop, restart bluepill

RETVAL=0
if [[ -s /usr/local/rvm/scripts/rvm ]] ; then source /usr/local/rvm/scripts/rvm ; fi
case "$1" in
start)
for i in /etc/bluepill/*.pill; do
/usr/local/rvm/gems/ruby-1.9.2-p180/bin/bluepill load $i
done
RETVAL=$?
;;
stop)
/usr/local/rvm/gems/ruby-1.9.2-p180/bin/bluepill stop
/usr/local/rvm/gems/ruby-1.9.2-p180/bin/bluepill quit
RETVAL=$?
;;
restart)
/usr/local/rvm/gems/ruby-1.9.2-p180/bin/bluepill restart
RETVAL=$?
;;
status)
/usr/local/rvm/gems/ruby-1.9.2-p180/bin/bluepill status
RETVAL=$?

*)
echo "Usage: bluepill {start|stop|restart|status}"
exit 1

esac
exit $RETVAL

还有一个愚蠢的问题,脚本运行后 bluepill 是否会加载到内存中?ps -ef | grep bluepill
