linux安装redis
wget http://download.redis.io/releases/redis-4.0.8.tar.gz
二、解压
tar -xzvf /usr/local/redis-4.0.8.tar.gz
三、安装
cd /usr/local/redis-4.0.8 #切换到解压目录
make #编译
make install PREFIX=/usr/local/redis-4.0.8 #安装到该目录下
四、
五、配置redis后台启动，不bind ip（可以远程访问）
vi /usr/local/redis-4.0.8/redis.conf #编辑配置文件
修改daemonize no==》daemonize yes 后台启动
修改bind 127.0.0.1==》#bind 127.0.0.1（注释掉才可以远程访问）
修改protected-mode yes==》 protected-mode no (no才可以远程访问)
六、将redis设置开机启动
vi /etc/rc.local
添加配置：
/usr/local/redis-4.0.8/bin/redis-server /usr/local/redis-4.0.8/redis.conf #开机时会调用该文件里面的命令
七、开启redis
/usr/local/redis-4.0.8/bin/redis-server /usr/local/redis-4.0.8/redis.conf
八、将redis-cli,redis-server拷贝到local/bin下,就可以全局使用这两个命令了
cp /usr/local/redis-4.0.8/bin/redis-server /usr/local/bin/
cp /usr/local/redis-4.0.8/bin/redis-cli /usr/local/bin/
九、设置密码
1、进入客户端输入命令:
config set requirepass "123456" #服务重启时失效
2、修改配置文件
vi /usr/local/redis-4.0.8/redis.conf
在#requirepass foobared下添加配置
requirepass 123456（你的密码）
重启redis即可
netstat -tunlp | grep 6379 #获取redis进程
kill -9 pid #杀掉redis进程
/usr/local/redis-4.0.8/bin/redis-server /usr/local/redis-4.0.8/redis.conf #启动
十、开放6397端口
systemctl start firewalld #开启防火墙
firewall-cmd --zone=public --add-port=6397/tcp --permanent #开放指定端口
firewall-cmd --reload #重启防火墙
firewall-cmd --zone=public --list-ports #查看开放的端口
脚本一键安装：
chmod 755 redis-install.sh && sh redis-install.sh 4.0.10
脚本：
#! /usr/bin/bash
##redis任何版本全程自动化源码编译安装
##用法：sh redis-install.sh 4.0.10 （后面跟的是你需要的版本号，需要什么版本就写什么版本），我这里安装的4.0.10

usage(){
echo "usage: $0 version"
