Mongodb rpm安装,自启动报错--got signal 1 (Hangup), will terminate after current cmd ends

今天被问到 mongodb,centos 7.6的自启动,报错

Jun 16 11:34:39 localhost rc.local: ERROR: child process failed, exited with error number 1
Jun 16 11:34:39 localhost rc.local: To see additional information in this output, start without the "--fork" option.

查看log日志

发现是启动mongodb后,被某个进程给kill掉了

一开始的启动脚本

在/etc/init.d 下面一个脚本,比如auto_mongo.sh,

/usr/bin/mongod --fork -f /etc/mongod.conf

然后添加chkconfig,单独运行脚本是可以的,就是开机启动不行。

检查了涉及到的文件和文件夹的权限

chown -R mongod:mongod /home/data/mongodb
chown -R mongod:mongod /usr/bin/mongo

在启动的时候 也显式的加了--fork,还是报错

 

于是新找了一台centos 7.4 ,进行rpm安装

使用root权限都不能编辑某个文件,很可能是使用chattr命令锁定该文件了。通过chattr命令修改属性能够提高系统的安全性,
但是它并不适合所有的目录。chattr命令不能保护/、/dev、/tmp、/var目录。lsattr命令是显示chattr命令设置的文件属性。
# chattr +i /etc/shadow ##使用chattr -i file加锁

[root@iscsi opt]# lsattr /etc/shadow
----i----------- /etc/shadow
[root@iscsi opt]# chattr -i /etc/shadow

然后重启是ok的。

-----------------

在出问题的机器上进行调试

在/etc/rc.d/rc.local加入strace命令,进行启动程序跟踪(在正常启动与不正常的日志中进行对比)

strace -tt -s 10000 -f -o  mongo.txt /usr/bin/mongod --fork -f /etc/mongod.conf

Mongodb rpm安装,自启动报错--got signal 1 (Hangup), will terminate after current cmd ends

 

 发现有涉及selinux;;这个时候,他们说他们安装的时候没有关闭selinux,于是他们关闭了selinux,然后自启动,就可以了~~~~

请注意:我在另外安装rpm的时候,一开始就关闭selinux,所以没有第一时间想到这里,走了一定的弯路。。。。
