本文详细介绍了如何解决Redis在运行过程中出现的警告信息，包括调整TCP backlog设置、解决内存过度承诺问题以及禁用透明大页功能，通过修改sysctl.conf配置文件和执行特定命令来提升Redis性能。

WARNING: The TCP backlog setting of 511 cannot be enforced because /proc/sys/net/core/somaxconn is set to the lower value of 128.

解决办法: vi etc/sysctl.conf 在配置文件中添加 net.core.somaxconn= 1024 这句话

WARNING overcommit_memory is set to 0! 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.

解决办法: vi /etc/sysctl.conf 在配置文件中添加 vm.overcommit_memory = 1 这句话,保存之后运行
echo never > /sys/kernel/mm/transparent_hugepage/enabled 这句命令

WARNING you have Transparent Huge Pages (THP) support enabled in your kernel. This will create latency and memory usage issues with Redis. To fix this issue run the command ‘echo never > /sys/kernel/mm/transparent_hugepage/enabled’ as root, and add it to your /etc/rc.local in order to retain the setting after a reboot. Redis must be restarted after THP is disabled.

解决办法: echo never > /sys/kernel/mm/transparent_hugepage/enabled 运行这句话之后就好了
