需要在服务器上执行sysctl vm.overcommit_memory=1或者执行一下语句: echo"vm.overcommit_memory = 1">> /etc/sysctl.conf \&& sysctl -p
很简单,按提示的操作(将vm.overcommit_memory 设为1)即可: 有三种方式修改内核参数,但要有root权限:(直接修改宿主机的配置文件) (1)编辑/etc/sysctl.conf ,改vm.overcommit_memory=1,然后sysctl -p 使配置文件生效 (2)sysctl vm.overcommit_memory=1 (3)echo 1 > /proc/sys/vm/overcommit_memory ——— ...
将vm.overcommit_memory设为1即可。 方式1、编辑/etc/sysctl.conf ,改vm.overcommit_memory=1,然后sysctl -p使配置文件生效 方式2、sysctl vm.overcommit_memory=1 方式3、echo 1 > /proc/sys/vm/overcommit_memory,然后sysctl -p永久生效,如果没有/etc/sysctl.conf,则每次开机都需要设置一次 方法二: 使用vfor...
// 内核模块中的参数设置module_param(overcommit_memory,int,0644);MODULE_PARM_DESC(overcommit_memory,"Memory overcommit mode"); 1. 2. 3. “通过熟悉内核源代码,能够精准定位及修改所需内核参数。” 以下是查找Docker源代码中对内核参数读写的简单示例: // Docker中调用内核参数设置syscall.Sysctl("vm.overc...
首先是 sysctl宿主主机查看 vm.overcommit_memory 默认是 0 : [root@localhost redis]# sysctl vm.overcommit_memoryvm.overcommit_memory=0 容器中查看 vm.overcommit_memory 默认也是 0 : [root@localhost redis]# docker exec -it redis sh/data # sysctl vm.overcommit_memoryvm.overcommit_memory=0 现在修改...

Background save may fail under low memory condition. To fix this issue add ‘vm.overcommit_memory = 1’ to /etc/sysctl.conf and then reboot or run the command ‘sysctl vm.overcommit_memory=1’ for this to take effect.”。有效性和必要性正在测试中。可以先忽略这一步。

docker run --rm -it --privileged ubuntu:22.04 sysctl vm.overcommit_memory=1 Then you can test it: docker run --rm -it ubuntu:22.04 sysctl vm.overcommit_memory You can’t make it permanent, but you can run it manually when you start Docker Desktop or use “depend_on” in a ...
