修改/data/app_platform/redis/conf/redis.conf配置,具体配置根据各自需要进行设置
redis 2.8中新增加的配置
# TCP listen() backlog. # # In high requests-per-second environments you need an high backlog in order # to avoid slow clients connections issues. Note that the Linux kernel # will silently truncate it to the value of /proc/sys/net/core/somaxconn so # make sure to raise both the value of somaxconn and tcp_max_syn_backlog # in order to get the desired effect. tcp-backlog 511

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. [16854] 24 Jan 22:31:27.114 # 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.

根据日志提示调整系统配置
echo "vm.overcommit_memory = 1" >> /etc/sysctl.conf ;sysctl -p
echo never > /sys/kernel/mm/transparent_hugepage/enabled 并且把这行添加到/etc/rc.local中使主机重启后仍然生效
echo "net.core.somaxconn = 2048" >> /etc/sysctl.conf;sysctl -p
然后再重新启动Redis
