sysctl -p

关闭大页内存：
echo never > /sys/kernel/mm/transparent_hugepage/enabled
echo never > /sys/kernel/mm/transparent_hugepage/defrag
echo "echo never > /sys/kernel/mm/transparent_hugepage/enabled" >> /etc/rc.d/rc.local
echo "echo never > /sys/kernel/mm/transparent_hugepage/defrag" >> /etc/rc.d/rc.local
chmod a+x /etc/rc.d/rc.local

操作系统ntp服务设置：
#检查当前系统时区，如果不是上海，修改为上海
timedatectl |grep "Time zone"
timedatectl set-timezone Asia/Shanghai
cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

安装ntp服务
yum install ntpdate -y
#写入定时任务同步时间
crontab -e
0-59/10 /usr/sbin/ntpdate ntp1.aliyun.com | logger -t NTP
#测试同步时间是否可以成功
/usr/sbin/ntpdate ntp1.aliyun.com

服务部署、依赖部署：
yum install gcc wget -y

2.redis软件下载及安装:
cd /usr/local
wget http://download.redis.io/releases/redis-4.0.11.tar.gz
tar xvzf redis-4.0.11.tar.gz
ln -s redis-4.0.11 redis
cd redis
make
make install
cd ~

vim .bash_profile
PATH=$PATH:$HOME/bin:/usr/local/redis/src
source .bash_profile
#验证是否安装成功,如果出现版本号则说明安装成功：
redis-cli -v

mkdir -p /data/redis-6379/logs/
mkdir -p /data/redis-6379/run/
编辑redis配置文件：
根据需要修改maxmemory和port参数以及对应的bind，例如端口号为6379，sed -i 's/6379/xxxx/g' xxxx.conf
配置文件port6379，IP地址192.168.56.201：

redis-cli -p 6379
添加定时任务定时做rdb备份和aof备份：
0 redis-cli -p 6379 bgsave
0 1 * redis-cli -p 6379 BGREWRITEAOF
