Linux安装redis和基本配置（linux redis安装步骤）

Redis是一个非关系型数据库管理系统（NoSQL-Not Only SQL），NoSQL意思是不仅仅是SQL，泛指非关系型数据库，不需要预先定义数据存储结构，每条记录都可以有不同的数据类型和字段个数。

安装Redis编译所需要的依赖库文件，我这里以CentOS来演示，其它版本的Linux发行版操作类似。

yum -y install gcc
yum -y install make

下载最新稳定的源码包6.2.6

wget https://download.redis.io/releases/redis-6.2.6.tar.gz

也可以去radis的官方网站下载。https://redis.io/download/

对源码包进行解包

tar -zxvf redis-6.2.6.tar.gz

进入到源码目录并编译源码文件，编译时间根据机器配置决定，请耐心等待。

cd redis-6.2.6/
make && make install

执行安装命令，这个是作者为我们写好的安装脚本，执行它就能把redis安装到我们的机器上。

./utils/install_server.sh

如果出现上面图片中的警告，注释掉脚本中的代码，约在80行左右。

#bail if this system is managed by systemd
#_pid_1_exe="$(readlink -f /proc/1/exe)"
#if [ "${_pid_1_exe##*/}" = systemd ]
#then
# echo "This systems seems to use systemd."
# echo "Please take a look at the provided example service unit files in this directory, and adapt and install them. Sorry!"
# exit 1
#fi
unset _pid_1_exe

然后重新执行脚本。一路回车，按照默认的路径安装Redis

[root@iZ2zefpm1mc6a69pa4afwjZ redis-6.2.6]# ./utils/install_server.sh
Welcome to the redis service installer
This script will help you easily set up a running redis server
Please select the redis port for this instance: [6379]
Selecting default: 6379
Please select the redis config file name [/etc/redis/6379.conf]
Selected default - /etc/redis/6379.conf
Please select the redis log file name [/var/log/redis_6379.log]
Selected default - /var/log/redis_6379.log
Please select the data directory for this instance [/var/lib/redis/6379]
Selected default - /var/lib/redis/6379
Please select the redis executable path [/usr/local/bin/redis-server]
Selected config:
Port : 6379
Config file : /etc/redis/6379.conf
Log file : /var/log/redis_6379.log
Data dir : /var/lib/redis/6379
Executable : /usr/local/bin/redis-server
Cli Executable : /usr/local/bin/redis-cli
Is this ok? Then press ENTER to go on or Ctrl-C to abort.
Copied /tmp/6379.conf => /etc/init.d/redis_6379

一路回车，端口 6379，配置文件 /etc/redis/6379.conf

看起是否启动，已经默认启动了。

ps -ef|grep redis

[root@iZ2zefpm1mc6a69pa4afwjZ redis-6.2.6]# ps -ef|grep redis
root 38675 1 0 18:37 ? 00:00:00 /usr/local/bin/redis-server 127.0.0.1:6379
root 38681 34173 0 18:38 pts/0 00:00:00 grep --color=auto redis

安装完成后，就可以启动服务了，使用以下的命令。

#启动redis
/etc/init.d/redis_6379 start
#关闭redis
/etc/init.d/redis_6379 stop

连接redis测试

[root@iZ2zefpm1mc6a69pa4afwjZ redis-6.2.6]# redis-cli
127.0.0.1:6379> set name zhu
OK
127.0.0.1:6379> get name
"zhu"
127.0.0.1:6379> exit
[root@iZ2zefpm1mc6a69pa4afwjZ redis-6.2.6]#

安装后自动默认配置，127.0.0.1 端口6379

找到配置文件 /etc/redis/6379.conf vi /etc/redis/6379.conf

# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
bind 127.0.0.1 -::1
# Protected mode is a layer of security protection, in order to avoid that
# Redis instances left open on the internet are accessed and exploited.

绑定ip地址，默认配置中只有一行bind 127.0.0.1，所以只有本地可以访问，如果想要别的ip能够访问，那么需要bind新的ip。

配置端口

# Accept connections on the specified port, default is 6379 (IANA #815344).
# If port 0 is specified Redis will not listen on a TCP socket.
port 6379
# TCP listen() backlog.
