Centos7安装Redis并设置远程访问

下载安装文件

wget http://download.redis.io/releases/redis-4.0.2.tar.gz

安装编译器

yum install gcc-c++

Redis安装文件复制到/usr/local/src目录下，进入/usr/local/src目录下，解压redis安装文件

cd /usr/local/src
tar -xzvf redis-4.0.2.tar.gz

进入解压后的文件目录，之后直接编译即可

cd /usr/local/src/redis-4.0.2

make

创建存储redis文件目录,复制redis-server redis-cli到新建立的文件夹

mkdir -p /usr/local/redis
cp /usr/local/src/redis-4.0.2/src/redis-server /usr/local/redis/
cp /usr/local/src/redis-4.0.2/src/redis-cli /usr/local/redis/

设置Redis开机自动启动

进入/usr/local/src/redis-4.0.2的util目录, 执行./install_server.sh

[root@localhost utils]# ./install_server.sh 
Welcome to the redis service installer

查看Redis进程

ps -ef|grep redis

Redis开启远程访问

# 查找Redis配置（注意不是安装目录下的redis.conf）
# 打开第五步设计的Redis配置，默认为：/etc/redis/6379.conf
# 修改配置文件如下几项，其它保持不变
daemonize yes
#bind 127.0.0.1 （注释，不限制IP）
protected-mode no
将 requirepass foobared前的“#”去掉，密码改为你想要设置的密码（我设置为123456）

# 重启服务
[root@172 redis-3.2.11]# service redis_6379 restart
Stopping ...
Redis stopped
Starting Redis server...

# 开放6379端口
firewall-cmd --zone=public --add-port=6379/tcp --permanent
# 重启防火墙，否则开放端口不起作用
firewall-cmd --reload

创建redis命令软连接

ln -s /usr/local/redis/redis-cli /usr/bin/redis
# 这样就可以输入进入redis进行控制台了
[root@localhost ~]# redis
127.0.0.1:6379> auth "123456"
OK
127.0.0.1:6379> 

关闭redis服务

service redis_6379 stop
Stopping ...
OK
(error) NOAUTH Authentication required.

## 报错

解决方法：修改redis服务脚本，加入如下所示的信息即可：

vim /etc/init.d/redis_6379
# 修改 添加 -a "password"
$CLIEXEC -a "123456" -p $REDISPORT shutdown
# 关闭redis服务
[root@localhost init.d]# service redis_6379 stop
Stopping ...
Warning: Using a password with '-a' or '-u' option on the command line interface may not be safe.
Redis stopped
