redis安装配置参考

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
