centos7安装redis设置开机启动

1. 首先下载redis源码，并使用tar进行解压缩

wget http://download.redis.io/releases/redis-4.0.8.tar.gz
tar xvzf redis-4.0.8.tar.gz
2.使用gcc进行编译

make
make test
编译后的可执行文件在redis-4.0.8/src目录下

3.使用root权限创建redis文件目录,并复制redis-server redis-cli

mkdir -p /usr/local/redis
cp src/redis-server /usr/local/redis/
cp src/redis-cli /usr/local/redis/
cp redis.conf /usr/local/redis/

sudo gropdadd redis
sudo useradd -g redis redis --no-create-home
sudo chown -R redis:redis /usr/local/redis
4.编辑配置文件redis.conf，将daemonize 改为yes支持后台运行

cd /usr/local/redis/
vim redis.conf

5.添加开机启动服务

vim /etc/systemd/system/redis-server.service
添加如下内容

[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=/usr/local/redis/redis-server /usr/local/redis/redis.conf
ExecStop=/usr/local/redis/redis-cli shutdown
Restart=always

[Install]
WantedBy=multi-user.target
设置为开机启动

systemctl daemon-reload
systemctl start redis-server.service
systemctl enable redis-server.service
创建redis-cli软连接

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