Doris 启动 BE 报错：file descriptors limit is too small

测试环境启动 BE 失败，提示如下：

E1216 10:50:15.593854  9129 storage_engine.cpp:419] File descriptor number is less than 60000. Please use (ulimit -n) to set a value equal or greater than 60000

F1216 10:50:15.594342  9129 doris_main.cpp:199] fail to open StorageEngine, res=file descriptors limit is too small

解决办法

修改 /etc/security/limits.conf, 执行命令：

echo "* soft nofile 204800" >> /etc/security/limits.conf
echo "* hard nofile 204800" >> /etc/security/limits.conf
echo "* soft nproc 204800" >> /etc/security/limits.conf
echo "* hard nproc 204800 " >> /etc/security/limits.conf

修改 /etc/sysctl.conf, 执行命令：

echo fs.file-max = 6553560 >> /etc/sysctl.conf

重启BE服务器，重启BE进程

注：此解决办法不适用在docker中启动的BE，docker 中启动的 BE 遇到此问题， 上面的方法不能解决，可参考: https://www.cnblogs.com/JenningsMao/p/9209689.html。
