2.下载Redis
Redis官方下载链接
下载安装包：
wget http://download.redis.io/releases/redis-5.0.7.tar.gz
3.解压/编译/安装
- 先准备个文件夹 /usr/local/redis 将解压后的文件存放在该目录
tar -zxvf redis-5.0.7.tar.gz -C /usr/local/redis
- 等待解压完成 cd 到/usr/local/redis目录下 查看解压后的文件
- cd到redis-4.0.9目录下 运行编译命令
make MALLOC=libc
- 等待编译完成 cd 到redis-4.0.9下的src目录 运行安装命令
make install
- 等待安装完成 会自动在/usr/local/bin目录下生成redis相关的可执行文件 可以cd到该目录下查看一下
4. 启动Redis
我们以后也可以在该目录下用./redis-server来启动redis 也可以在刚刚的src目录下运行./redis-server
无论用哪个目录下的./redis-server都可以启动redis 我们来试一下
/usr/local/bin目录 启动redis【./redis-server】
/usr/local/redis/redis-5.0.7/src 目录启动redis 【./redis-server】
[root@instance-6uz2q7zs bin]# ./redis-server

15886:C 02 Feb 2020 14:53:32.730 # Warning: no config file specified, using the default config. In order to specify a config file use ./redis-server /path/to/redis.conf

如上图 redis就成功启动了 当然这种并不是后台启动(守护线程)的方式 因为退出该窗口redis就关闭了 接下来我来教大家如何以守护线程启动redis
5.守护线程(后台启动)方式启动redis
首先按ctrl+c退出该窗口 我们cd 到redis的解压目录下 我们可以看到有个redis.conf文件 这个文件是redis的配置文件
vim 打开redis.conf文件
我们可以看到有个daemonize配置项 这个就是后台启动的意思 将no改成yes即可 修改完之后 保存退出(修改配置文件并保存退出这里我就不介绍了哈)
5.1 启动Redis
这时候我们再去启动 要知道启动文件在src目录下 cd 到src目录 运行如下命令
./redis-server ../redis.conf
运行该目录下的启动文件redis-server 再将上级目录下的redis.conf配置文件带进去 就可成功后台启动redis了
这时候 我们可以去看一下redis是否启动成功
如上图 redis我们成功后台启动了
到此完成
若关闭redis 可以直接 kill -9 16582
6 远程连接redis
6.1 修改redis配置文件
找到redis的安装目录
vim redis.conf
bind 0.0.0.0
protected-mode no
关闭redis后重启redis
远程连接Redis 成功
