问题一：

/var/log/messages系统日志报错如下

Apr 30 09:20:01 sr_web_server_01 systemd: Created slice user-0.slice.

通过以上报错日志：

Executable ‘/data/node-v12.14.1-linux-x64/bin/node‘ doesn‘t belong to any package and ProcessUnpackaged is set to ‘no‘

得知是因为无法创建ccpp文件导致的,可以修改/etc/abrt/abrt-action-save-package-data.conf文件中的ProcessUnpackaged参数为yes,

cat /etc/abrt/abrt-action-save-package-data.conf

# With this option set to "yes",

# only crashes in signed packages will be analyzed.

# the list of public keys used to check the signature is

# in the file gpg_keys

#

# How can I check the GPG key used to sign an installed pacakge on

# Red hat Enterprise Linux:

# https://access.redhat.com/solutions/1120013

#

# Product Signing (GPG) Keys:

# https://access.redhat.com/security/team/key

#

OpenGPGCheck = yes

# Blacklisted packages

#

BlackList = nspluginwrapper, valgrind, strace, mono-core

# Process crashes in executables which do not belong to any package?

#

ProcessUnpackaged = yes

# Blacklisted executable paths (shell patterns)

#

BlackListedPaths = /usr/share/doc/*, */example*, /usr/bin/nspluginviewer, /usr/lib/xulrunner-*/plugin-container

# interpreters names

Interpreters = python2, python2.7, python, python3, python3.3, perl, perl5.16.2

也可以使用sed命令进行关键字替换

sed -i ‘s/ProcessUnpackaged = no/ProcessUnpackaged = yes/g‘

修改配置文件完成之后，记得重启abrtd服务

systemctl restart abrtd

问题二：

如果配置了定时任务，正常情况下应该发送系统邮件，即cron没有将任务的执行结果发送邮件通知到用户

报错信息如下：

crond: sendmail: fatal: parameter inet_interfaces: no local interface found for ::1

解决方法：修改vim /etc/postfix/main.cf配置文件

inet_interfaces = all

重启postfix服务

systemctl restart postfix.service
