WARNING - script '/etc/keepalived/XXXXXX' is not executable for uid:gid 0:0 - disabling.
Unsafe permissions found for script '/etc/keepalived/XXXXXXX'
WARNING - default user 'keepalived_script' for script execution does not exist - please create.
背景
在使用keepalived的时候,我们可能会作息配置,配置一些脚本,例如检测服务的脚本,例如当keepalived成为主节点的时候。如下脚本就是当keepalived成为主节点的时候,执行的脚本。
notify_master "/etc/keepalived/bin/recover.sh"
但是这个脚本的权限却被keepalived检测出来是不安全的,或者被检测出来是不可执行的,或者会有其他的一些警告。让我们一一解决。
WARNING - script '/etc/keepalived/bin/check.sh' is not executable for uid:gid 0:0 - disabling.
首先我们先去查看脚本的权限,如下图所示,脚本在没有执行权限,需要赋予执行权限。
chmod 744 /etc/keepalived/bin/check.sh
Unsafe permissions found for script '/etc/keepalived/bin/recover.sh'.
查看脚本权限,发现权限是777,这样不行,改成744.
chmod 744 /etc/keepalived/bin/recover.sh
WARNING - default user 'keepalived_script' for script execution does not exist - please create.
这个错误的原因在于配置文件的错误,在global_defs中加入如下两行即可。
script_user root
enable_script_security
打开配置文件。
vi /etc/keepalived/keepalived.conf
找到相应位置添加即可。
重启服务,测试结果
systemctl stop keepalived
systemctl start keepalived
