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:
