Linux 安装和配置Redis

1、上传Redis安装压缩包到服务器/opt目录上

2、redis是由C语言编写，运行需要C环境，安装gcc等

yum install -y gcc gcc-c++ tcl

3、创建redis用户组和用户

groupadd redis
useradd redis -g redis -s /sbin/nologin

4、解压

cd /opt
tar -zxvf redis-4.0.14.tar.gz

5、编译、指定目录安装

cd redis-4.0.14
make MALLOC=libc
make PREFIX=/opt/redis install

6、配置Redis环境变量

echo "export PATH=/opt/redis/bin:\$PATH" >> /etc/profile
source /etc/profile 

7、创建Redis存放日志、数据的目录

mkdir -pv /opt/redis/logs /opt/redis/data

8、修改redis.conf配置文件，下面“内网ip”根据实际修改

cp /opt/redis-4.0.14/redis.conf /opt/redis/
sed -i 's/bind 127.0.0.1/bind 内网ip/g' /opt/redis/redis.conf
sed -i 's/daemonize no/daemonize yes/g' /opt/redis/redis.conf
sed -i "s#^logfile.*#logfile /opt/redis/logs/redis.log#" /opt/redis/redis.conf
sed -i "s#^dir ./#dir /opt/redis/data#" /opt/redis/redis.conf

9、修改Redis所属权限

chown -R redis:redis /opt/redis

10、配置redis系统服务启动

vim /usr/lib/systemd/system/redis.service

编辑内容如下后保存：

[Unit]

Description=Redis Server Manager

After=syslog.target

After=network.target

 

[Service]

Type=simple

User=redis

Group=redis

PIDFile=/var/run/redis_6379.pid

ExecStart=/opt/redis/bin/redis-server /opt/redis/redis.conf --daemonize no

ExecStop=/opt/redis/bin/redis-cli shutdown

Restart=always

 

[Install]

WantedBy=multi-user.target

11、重新加载新的服务、设置Redis开机自启、启动服务、查看启动状态

systemctl daemon-reload
systemctl enable redis
systemctl start redis
systemctl status redis

备注：
Redis默认端口号6379不允许进行远程连接，需要在防火墙中设置6379允许远程连接。
