Redis安裝后直接啟動會提示三個錯誤,如下:
[lb@centos-linux src]$ ./redis-server 1988:C 19 Apr 2021 00:33:16.869 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo 1988:C 19 Apr 2021 00:33:16.869 # Redis version=6.2.1, bits=64, commit=00000000, modified=0, pid=1988, just started 1988:C 19 Apr 2021 00:33:16.869 # Warning: no config file specified, using the default config.

為解決這個問題,可已通過如下配置進(jìn)行解決,具體操作如下:
修改linux系統(tǒng)配置
[root@centos-linux lb]# vim /etc/sysctl.conf
添加配置
net.core.somaxconn = 1024 vm.overcommit_memory = 1
添加完成后,刷新內(nèi)核參數(shù),立即生效
[redis-5.0.8]$ /sbin/sysctl -p
