  安装时添加 MALLOC=libc

• 启动 Redis

~]# ln -s /usr/local/redis/bin/* /usr/local/sbin/
~]# mkdir /usr/local/redis/etc
~]# cp /usr/local/src/redis-4.0.14/redis.conf /usr/local/redis/etc/
~]# redis-server /usr/local/redis/etc/redis.conf

• 解决办法

# 第一个问题
~]# vim /usr/local/redis/etc/redis.conf
tcp-backlog 128
# 或者修改 /etc/sysctl.conf
~]# vim /etc/sysctl.conf
net.core.somaxconn = 512
~]# sysctl -p
net.core.comaxconn = 512
# 第二个问题
~]# vim /etc/sysctl.conf
vm.overcommit_memory = 1
~]# sysctl -p
sysctl vm.overcommit_memory = 1
# 第三个问题
~]# echo never > /sys/kernel/mm/transparent_hugepage/enabled
~]# vim /etc/rc.d/rc.local
echo never > /sys/kernel/mm/transparent_hugepage/enabled
~]# chmod a+x /etc/rc.d/rc.local
~]# reboot
# 重启查看 Redis 启动状态
~]# vim /usr/lib/systemd/system/redis.service
