磁盘被谁占满了

磁盘被占满了,想知道被谁占满,怎么办?首先想到的是搜索所有超过GB大小的文件。
查看超过1GB的文件
#命令就是这样不用改别奇怪。查看/下所有单位是G的文件 du -h / |grep -E "G[[:space:]]"

create user 'repl'@'%' identified by 'password'; grant replication slave on *.* to 'repl'@'%';
#/etc/mysql/my.conf server-id=1 gtid_mode=ON enforce-gtid-consistency=true

change master TO master_host='192.168.50.111', master_port=3307, master_user='repl', master_password='password', master_auto_position=1;
start slave
#Slave_IO_Running/Slave_SQL_Running两个都是yes表示配置成功 show slave status;

BBR是来自Google的黑科技,通过优化和控制TCP的拥塞,充分利用带宽并降低延迟,起到神奇的加速效果。
centos7.5
加速效果,没有那么跨张,但是下载从50K加速到400K
rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org rpm -Uvh http://www.elrepo.org/elrepo-release-7.0-3.el7.elrepo.noarch.rpm yum --enablerepo=elrepo-kernel install kernel-ml -y
rpm -qa | grep kernel
egrep ^menuentry /etc/grub2.cfg | cut -f 2 -d \' grub2-set-default 0 # default 0 表示第一个内核设置为默认运行, 选择最新内核就对了 reboot
uname -r
modprobe tcp_bbr echo "tcp_bbr" | sudo tee --append /etc/modules-load.d/modules.conf
echo "net.core.default_qdisc=fq" | sudo tee --append /etc/sysctl.conf echo "net.ipv4.tcp_congestion_control=bbr" | sudo tee --append /etc/sysctl.conf sysctl -p
sysctl net.ipv4.tcp_available_congestion_control sysctl net.ipv4.tcp_congestion_control
如果结果都有 bbr, 则证明你的内核已开启 bbr
执行 lsmod | grep bbr, 看到有 tcp_bbr 模块即说明 bbr 已启动

尝试了很多方法,很奇怪它为什么不能应答。dnsmasq也不大,放在宿主机上运行吧。
