Redis部署

安装前准备

下载安装包

安装依赖
yum -y install gcc automake autoconf libtool make

创建用户

useradd redis
passwd redis

[root@myhost redis]# mkdir /home/redis/6379

[root@myhost redis]# chown -R redis:redis /home/redis/6379/

tar -zxvf redis-4.0.10.tar.gz 
ln -s redis-4.0.10 redis
cd redis
make
vim ~/.bash_profile
export PATH=/home/redis/redis/src:$PATH
source ~/.bash_profile

启动
redis-server &

连接
[redis@myhost ~]$ redis-cli
127.0.0.1:6379> 
127.0.0.1:6379> set num 100
OK
127.0.0.1:6379> get num
"100"

配置文件

cp redis/redis.conf 6379/redis.conf

修改配置文件
去掉注释，保存到6379.conf 
grep -Ev "$^|#" 6379/redis.conf  > 6379/6379.conf
