我想重新启动Unicorn以查看我在某些视图上进行的本地编辑。
我能够阻止独角兽。由于某种原因，它不会重新启动。
这是它给我的错误：
Executing /etc/rc.d/init.d/unicorn_loadmax start ..
/etc/rc.d/init.d/unicorn_loadmax: line 20: kill: (24317) - No such process
master failed to start, check stderr log for details
这是我的独角兽脚本

我DID更改第26行昨天......
将2048改为50M
答案 0 :(得分：0)
您应该检查日志以确定错误。但是，一个简单的解决方法是终止进程并重新启动独角兽。
ps aux | grep unicorn
然后，在那里找到主进程。
kill <process-id>
然后，尝试再次启动服务器。
答案 1 :(得分：0)
您的脚本在以下行崩溃：
test -s "$PID" && kill -$1 `cat $PID`
$PID设置为：
PID=/home/deployer/loadmax/shared/pids/unicorn.pid
和test -s检查文件是否存在，并且大小大于零。
尝试删除此文件，然后再次运行脚本。
至于第26行 - 尝试删除M - 它不是一个数字...... - 只需放50
