Redis安裝后直接啟動(dòng)會(huì)提示三個(gè)錯(cuò)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. In order to specify a config file use ./redis-server /path/to/redis.conf 1988:M 19 Apr 2021 00:33:16.870 # You requested maxclients of 10000 requiring at least 10032 max file descriptors. 1988:M 19 Apr 2021 00:33:16.870 # Server can't set maximum open files to 10032 because of OS error: Operation not permitted. 1988:M 19 Apr 2021 00:33:16.870 # Current maximum open files is 4096. maxclients has been reduced to 4064 to compensate for low ulimit.

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. 1988:M 19 Apr 2021 00:33:16.872 * Ready to accept connections
為解決這個(gè)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
