概述： 很多时候我们通过系统本身yum、apt等方式，安装的redis的时候，安装的版本都不是较新的版本或我们所需要的版本，这时我们需要用源码安装，这样就就可以随意的选择我们自己指定的版本了，下面我们来简单介绍通过源码包的方式，安装redis6.0版本。

版本环境：redis 6.2.1

1、准备安装目录：

#mkdir -p /usr/local/redis6csdb/6379/{conf,data,log}

2、下载安装包编译安装（需提前安装好编译工具如gcc、make）

#wget https://download.redis.io/releases/redis-6.2.1.tar.gz && tar -zxvf redis-6.2.1.tar.gz

#cd redis-6.2.1 && make && make install

3、配置文件编辑

#vim /usr/local/redis6csdb/6379/conf/redis.conf

bind 0.0.0.0

protected-mode no

port 6379

hz 10

dynamic-hz yes

aof-rewrite-incremental-fsync yes

rdb-save-incremental-fsync yes

jemalloc-bg-thread yes

4、增加redis6在系统中自启动

#vin /usr/lib/systemd/system/redis.service

[Unit]

Description=redis-server6379

After=network.target

[Service]

Type=forking

ExecStart=/usr/local/redis6/bin/redis-server /usr/local/redis6csdb/6379/conf/redis.conf

ExecStop=/usr/local/redis6/bin/redis-cli -h 127.0.0.1 -p 6379 shutdown

PrivateTmp=true

#systemctl restart redis && systemctl enable redis

5、系统参数调整

####sysctl.conf

#echo "vm.overcommit_memory = 1" >> /etc/sysctl.conf

#echo "net.core.somaxconn = 2048" >> /etc/sysctl.conf

#sysctl vm.overcommit_memory=1

#sysctl net.core.somaxconn=2048

#sysctl -p

6、关于自带的保护模式：

1、设置protected-mode no模式，此时外部网络可以直接访问

2、设置protected-mode yes保护模式，需配置bind ip或者设置访问密码
