问题一: max number of threads [2048] for user [work] likely too low, increase to at least [4096] 解决方法:进入limits.d下的配置文件:vi /etc/security/limits.d/90-nproc.conf ,修改配置。
问题二: system call filters failed to install; 解决方法 在elasticsearch.yml中配置bootstrap.system_call_filter为false,注意要在Memory下面: bootstrap.memory_lock: false bootstrap.system_call_filter: false
