system call filters failed to install; check the logs and fix your configuration or disable system call filters at your own risk

cantOS 6.x版本

elasticsearch 6.x版本

es6.x版本默认bootstrap.system_call_filter检测为true, centos版本不支持, 导致检测失败

在elasticsearch.yml添加配置

#
# Lock the memory on startup:
#
bootstrap.memory_lock: false
#
# Make sure that the heap size is set to about half the memory available
# on the system and that the owner of the process is allowed to use this
# limit.
#
# Elasticsearch performs poorly when the system is swapping the memory.
#
bootstrap.system_call_filter: false
