Redis安装

这里介绍两种安装方式：使用docker安装Redis，以及直接在CentOS7下安装。

1. 使用Docker方式安装

搜索redis镜像：‍

使用docker拉取官方最新的redis镜像：

[root@localhost ~]# docker pull redis:latest
Trying to pull repository docker.io/library/redis ... 
latest: Pulling from docker.io/library/redis
e5ae68f74026: Pull complete 
37c4354629da: Pull complete 
b065b1b1fa0f: Pull complete 
6954d19bb2e5: Pull complete 
6333f8baaf7c: Pull complete

Status: Downloaded newer image for docker.io/redis:latest

查看本地镜像：

[root@localhost ~]# docker images
REPOSITORY                     TAG                 IMAGE ID            CREATED             SIZE
docker.io/redis                latest              aea9b698d7d1        4 days ago          113 MB

运行一个redis容器，默认使用6379端口：‍

[root@localhost ~]# docker run -itd --name docker_redis_server -p 6379:6379 redis
18352188dd9ecb617a32e3f061bf196c6271d13b98fd7d562e7f468c3204dd25

查看容器运行：

root@localhost ~]# docker ps -a
CONTAINER ID        IMAGE               COMMAND                  CREATED              STATUS              PORTS                              NAMES
18352188dd9e        redis               "docker-entrypoint..."   6 seconds ago        Up 5 seconds        0.0.0.0:6378->6378/tcp   docker_redis_server

测试使用redis：

[root@localhost ~]# docker exec -it docker_redis_server /bin/bash
root@18352188dd9e:/data# redis-cli
127.0.0.1:6379> set name zhangsan
OK
127.0.0.1:6379> get name
"zhangsan"
127.0.0.1:6379> quit
root@18352188dd9e:/data# exit
exit

2. 直接安装

下载、解压安装包：

[root@localhost ~]# yum install -y gcc 
[root@localhost ~]# wget https://download.redis.io/releases/redis-5.0.4.tar.gz
[root@localhost ~]# tar -zxvf redis-5.0.4.tar.gz

进入解压目录中，编译，安装：

[root@localhost ~]# cd redis-5.0.4
[root@localhost ~]# make
[root@localhost ~]# make install PREFIX=/usr/local/redis

至此，到这里安装完成，启动即可。下面启动它：

[root@localhost ~]# cd /usr/local/redis/bin/
[root@localhost bin]# ./redis-server

上面这种启动方式是在前台启动了。

创建一个redis客户端的软链接，测试一下：

[root@localhost bin]# ln -s /usr/local/redis/bin/redis-cli /usr/bin/redis-cli
[root@localhost ~]# redis-cli
127.0.0.1：6379> set name zhangsan
OK
127.0.0.1：6379> get name
"zhangsan"

前台启动一旦窗口关闭，就终止了。下面通过后台启动它：

# 拷贝一个配置文件
[root@localhost bin]# cp /usr/local/redis-5.0.4/redis.conf /usr/local/redis/bin/

# 编辑配置文件，把daemonize no改为daemonize yes
[root@localhost bin]# vim redis.conf
daemonize yes

# 启动服务
[root@localhost bin]# ./redis-server redis.conf
# 查看服务进程
[root@localhost bin]# ps -ef|grep redis
root      7954  5604  0 17:45 pts/1    00:00:00 grep --color=auto redis
root     21755     1  0 Aug30 ?        02:23:05 /usr/local/redis/bin/redis-server *:6379

现在，将它设置成开启启动：

# 编辑一个redis.service文件，添加下面内容
[root@localhost bin]# vim /etc/systemd/system/redis.service
[Unit]
Description=redis-server
After=network.target


[Service]
Type=forking
ExecStart=/usr/local/redis/bin/redis-server /usr/local/redis/bin/redis.conf
PrivateTmp=true


[Install]
WantedBy=multi-user.target


# 让文件生效
[root@localhost bin]# systemctl daemon-reload
# 启动服务
[root@localhost bin]# systemctl start redis.service
# 开机启动
[root@localhost bin]# systemctl enable redis.service
