1，yum install wget
2,cd ~
3,mkdir soft
4,cd soft
5,wget http://download.redis.io/releases/redis-5.0.5.tar.gz
6,tar xf redis…tar.gz
7,cd redis-src
8,看README.md
9, make
….yum install gcc
…. make distclean
10,make
11,cd src ….生成了可执行程序
12, cd ..
13,make install PREFIX=/opt/redis5
14,vi /etc/profile
… export REDIS_HOME=/opt/redis5
… export PATH=$PATH:$REDIS_HOME/bin
..source /etc/profile
15,cd utils
16,./install_server.sh （可以执行一次或多次）
a) 一个物理机中可以有多个redis实例（进程），通过port区分
b) 可执行程序就一份在目录，但是内存中未来的多个实例需要各自的配置文件，持久化目录等资源
c) service redis_6379 start/stop/stauts > linux /etc/init.d/****
d)脚本还会帮你启动！
【注意】
在安装redis6时会报错
This systems seems to use systemd.
Please take a look at the provided example service unit files in this directory, and adapt and install them. Sorry!
修改这个install_server.sh
把下面这一段进行注释
#bail if this system is managed by systemd
#_pid_1_exe="$(readlink -f /proc/1/exe)"
#if [ "${_pid_1_exe##*/}" = systemd ]
#then
# echo "This systems seems to use systemd."
# echo "Please take a look at the provided example service unit files in this directory, and adapt and install them. Sorry!"
# exit 1
#fi
