CentOS7 安装 Redis 并设置开机启动

1.下载

https://redis.io/download
cd /usr/local/src
wget -c http://download.redis.io/releases/redis-3.2.6.tar.gz

2.解压

cd /usr/local/src
tar xzf redis-3.2..tar.gz

3.编译

cd /usr/local/src/redis-3.2.6make

若出现错误则说明未安装gcc

yum install gcc && make MALLOC=libccd /usr/local/src/redis-3.2. &&
make

4.创建redis目录

mkdir -p /usr/local/redis

5.复制主要配置文件到新文件夹

cp /usr/local/src/redis-3.2./src/redis-server /usr/local/redis/
cp /usr/local/src/redis-3.2./src/redis-cli /usr/local/redis/
cp /usr/local/src/redis-3.2./redis.conf /usr/local/redis/

6.开启后台运行

vim /usr/local/redis/redis.conf
修改redis.conf文件中的daemonize no为daemonize yes并保存

7.创建redis命令软连接

ln -s /usr/local/redis/redis-cli /usr/bin/redis

在任意命令行执行redis

8.添加开机启动服务

vim /etc/systemd/system/redis-server.service

粘贴以下内容

[Unit]
Description=The redis-server Process Manager
After=syslog.target network.target

[Service]
Type=simple
PIDFile=/var/run/redis_6379.pid
ExecStart=/usr/local/redis/redis-server /usr/local/redis/redis.conf
ExecReload=/bin/kill -USR2 $MAINPID
ExecStop=/bin/kill -SIGINT $MAINPID

[Install]
WantedBy=multi-user.target

9.设置开机启动

systemctl daemon-reload
systemctl start redis-server.service
systemctl enable redis-server.servic

10.检查是否安装成功

ps -A|grep redis

11.连接登录

#交互式

#redis-cli -h {host} -p {port}
$redis-cli -h 127.0.0.1 -p
127.0.0.1：>set hello world
OK
127.0.0.1：>get hello
"world"

#命令式

#redis-cli -h {host} -p {port} {command}
$redis-cli -h 127.0.0.1-p  get hello
"world"

12.永久设置Redis密码

vim /etc/redis.conf
#在配置文件中有个参数：requirepass 这个就是配置redis访问密码的参数；
#比如 requirepass test123；

需重启Redis才能生效

13.临时设置Redis密码

redis 127.0.0.1:> config set requirepass test123

#查询密码：

redis 127.0.0.1:> config get requirepass
(error) ERR operation not permitted

#密码验证：

redis 127.0.0.1:> auth test123
OK

#再次查询：

redis 127.0.0.1:> config get requirepass
) "requirepass"
) "test123"

14.登陆有密码的Redis

redis-cli -p  -a test123

15.先登陆后验证

redis-cli -p
redis 127.0.0.1:> auth test123
OK

16.开启后台运行

将redis.conf中的"daemonize no"为"daemonize yes"并保存,重启redis生效。
