sync && echo 1 > /proc/sys/vm/drop_caches
执行 echo N > /proc/sys/vm/drop_caches,再free –m查看内存使用情况,输入不同的N值,free –m内存中缓存buffers会有差异,现在我们就是要解释/proc/sys/vm、drop_caches, 这个文件到底是什么?另外可以写入哪些数值,具体适用于什么场景
查看linux内核文档,可以得到以下信息:
修改 /etc/systemd/system.conf ,添加如下配置项:
[Manager]
DefaultLimitCORE=infinity
DefaultLimitNOFILE=10240000
DefaultLimitNPROC=10240000
使配置生效:
sudo systemctl daemon-reload
用户服务需要重启,如:
sudo systemctl restart nginx
验证:
cat /proc/[PID]/limits
使用 chromium 内核的全新浏览器,全平台下载地址:
在 wp-config.php
文件中,添加以下代码(可以放在 DEBUG
后面)
$_SERVER['HTTPS'] = 'on';
define('FORCE_SSL_LOGIN', true);
define('FORCE_SSL_ADMIN', true);
停止cluster 服务
systemctl stop pve-cluster.service
systemctl stop corosync.service
设置本地模式
pmxcfs -l
删除corosync 配置文件
rm /etc/pve/corosync.conf
rm -rf /etc/corosync/*
重启cluster集群服务
killall pmxcfs
systemctl start pve-cluster.service
删除 WEB-UI 上的除当前 node 外的 node
cd /etc/pve/nodes
rm -rf node_name
单文件
mkisofs -o mirr.iso /path/to/file
目录
mkisofs -r -o mirr.iso /path/to/dir
针对 manjaro ,但理论上适用于大多数 linux 系统。
先用 live 启动盘引导进入系统,按如下操作进行。
