bootstrap.memory_lock设置为true报错

报错信息如下:

[2021-02-20T08:56:57,870][WARN ][o.e.b.JNANatives         ] [Titlis] These can be adjusted by modifying /etc/security/limits.conf, for example:
        # allow user 'crate' mlockall
        crate soft memlock unlimited
        crate hard memlock unlimited

解决办法如下：

需要修改
/etc/security/limits.conf
crate soft memlock unlimited
crate hard memlock unlimited

这里的crate是运行crate程序的用户

修改：
/etc/sysctl.conf
vm.swappiness=0

不需要重启，执行下面的命令生效

systemctl daemon-reload

 

然后查看是否设置成功

ulimit -a检查是否设置成功
