解压

[root@test bak]# tar -zxvf redis-4.0.10.tar.gz 
[root@test bak]# cd redis-4.0.10
[root@test redis-4.0.10]#

编译安装

make
[root@test redis-4.0.10]# make MALLOC=libc
新建/usr/local/redis目录,将当前src目录下面的文件复制到/usr/local/redis中

[root@test redis-4.0.6]# cd src && make install
    CC Makefile.dep 
Hint: It's a good idea to run 'make test' ;)
 
    INSTALL install
    INSTALL install
    INSTALL install
    INSTALL install
    INSTALL install

启动redis

切找到/usr/local/redis目录下启动redis

[root@test redis]# ./redis-server

Redis must be restarted after THP is disabled.

后台启动redis

打开redis.conf,把daemonize设置为yes
daemonize yes

[root@test redis]# ./redis-server /usr/local/redis/redis.conf
10324:C 06 Jul 10:57:09.129 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo
10324:C 06 Jul 10:57:09.129 # Redis version=4.0.10, bits=64, commit=00000000, modified=0, pid=10324, just started
10324:C 06 Jul 10:57:09.129 # Configuration loaded

今天发现无法后台启动,需要修改daemonize值为yes

# By default Redis does not run as a daemon. Use 'yes' if you need it.
# Note that Redis will write a pid file in /var/run/redis.pid when daemonized.
# daemonize no
# 修改为yes值
# daemonize yes

设置访问密码

打开redis.conf配置文件，找到requirepass，然后修改如下:
requirepass yourpassword
重启redis生效

开启远程访问权限

解决办法：注释掉bind 127.0.0.1可以使所有的ip访问redis
若是想指定多个ip访问，但并不是全部的ip访问，可以bind

在redis3.2之后，redis增加了protected-mode，在这个模式下，即使注释掉了bind 127.0.0.1，再访问redisd时候还是报错，如下
修改办法：protected-mode no
