#安装部署redis

本文提供了一套详细的Redis单实例部署流程，包括下载、安装、配置等步骤，并介绍了如何进行开机自启动设置。

本教程是单实例部署，根据公司实际情况，是否用于生产，不建议用于生产，生产至少需要部署一个集群，测试环境需要安装一个，简单记录下。

1. 下载

wget http://download.redis.io/releases/redis-5.0.8.tar.gz

2. 安装依赖包

yum -y install gcc*

3. 解压并编译

tar -zxf redis-5.0.8.tar.gz 
cd redis-5.0.8 && make

4. 安装

将/data/redis-5.0.8/src目录下的文件加到/usr/local/bin目录

[root@localhost redis-5.0.8]# cd src
[root@localhost 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
[root@localhost src]#

mkdir -p /data/redis/data/ && mkdir -p /data/redis/logs

6. 配置文件修改

[root@localhost redis-5.0.8]# cat redis.conf |grep -viP "^#"|grep -v "^$"

[root@localhost redis-5.0.8]#

7. 配置开机启动

配置文件移动到/etc/目录

cp /data/redis-5.0.8/redis.conf /etc/redis/redis.conf

编辑 systemctl 服务配置文件

cat /lib/systemd/system/redis.service


[Unit]
Description=Redis
After=network.target


[Service]
Type=forking
PIDFile=/data/redis/logs/redis_6379.pid
ExecStart=//usr/local/bin/redis-server /etc/redis/redis.conf
ExecReload=/bin/kill -s HUP $MAINPID
ExecStop=/bin/kill -s QUIT $MAINPID
PrivateTmp=true


[Install]
WantedBy=multi-user.target

8. 启动测试

[root@localhost logs]# systemctl daemon-reload
[root@localhost logs]# systemctl start redis
[root@localhost logs]# systemctl status redis
● redis.service - Redis
   Loaded: loaded (/usr/lib/systemd/system/redis.service; enabled; vendor preset: disabled)
   Active: active (running) since Wed 2020-04-15 14:37:42 CST; 8s ago
  Process: 32698 ExecStart=/usr/local/bin/redis-server /etc/redis/redis.conf (code=exited, status=0/SUCCESS)
 Main PID: 32699 (redis-server)
   CGroup: /system.slice/redis.service
           └─32699 /usr/local/bin/redis-server 0.0.0.0:6379


Apr 15 14:37:42 localhost.localdomain systemd[1]: Starting Redis...
Apr 15 14:37:42 localhost.localdomain systemd[1]: New main PID 32441 does not exist or is a zombie.
Apr 15 14:37:42 localhost.localdomain systemd[1]: Started Redis.
[root@localhost logs]#

9. 设置开机启动

[root@localhost logs]# systemctl enable redis
Created symlink from /etc/systemd/system/multi-user.target.wants/redis.service to /usr/lib/systemd/system/redis.service.
[root@localhost logs]#

10. 总结

Redis 安装相对简单，但集群部署方式适合用于生产，后续总结生产部署集群的方式。
