无法启动Unicorn

Question

我想重新启动Unicorn，看看我在本地做的一些视图编辑。

我阻止了独角兽。由于某些原因，它将不会重新启动。

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

这是我的独角兽剧本

# since nginx and unicorn accept the same signals

Answer 1

您的脚本崩溃在以下一行：

test -s "$PID" && kill -$1 `cat $PID`

$PID设置为：

PID=/home/deployer/loadmax/shared/pids/unicorn.pid

test -s检查该文件是否存在，并且其大小大于零。

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.-简单地说是50

Answer 2

您应该检查日志中是否有确切的错误。但是，一个简单的修复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，再试着启动服务器。
