1.操作系统参数和服务配置： sed -i 's@SELINUX=enforcing@SELINUX=disabled@g' /etc/selinux/config systemctl stop firewalld systemctl disable firewalld
echo "vm.overcommit_memory=1" >> /etc/sysctl.conf echo "vm.swappiness=10" >> /etc/sysctl.conf echo 10 > /proc/sys/vm/swappiness echo "net.core.somaxconn=65535" >> /etc/sysctl.conf echo "net.ipv4.tcp_max_syn_backlog=65535" >> /etc/sysctl.conf echo "net.ipv4.tcp_max_syn_backlog=65535" >> /etc/sysctl.conf echo "net.core.somaxconn=65535" >> /etc/sysctl.conf echo "* soft nofile 288000" >> /etc/security/limits.conf echo "* hard nofile 288000" >> /etc/security/limits.conf 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：

启动Redis： redis-server /data/redis-6379/6379.conf 登录： 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
