gcc环境
Redis是由C语言开发，因此安装之前必须要确保服务器已经安装了gcc
查看gcc环境，查看到版本号输出，说明已经安装gcc
[hadoop@node2 installfile]$ gcc --version gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-44) Copyright (C) 2015 Free Software Foundation, Inc. This is free software; see the source for copying conditions. There is NO warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
1）安装或更新C语言的编译环境
[hadoop@node2 installfile]$ sudo yum install -y centos-release-scl scl-utils-build [hadoop@node2 installfile]$ sudo yum install -y devtoolset-8-toolchain[hadoop@node2 installfile]$ sudo scl enable devtoolset-8 bash
注意: 执行sudo scl enable devtoolset-8 bash会自动切换到 root 用户
效果如下
[hadoop@node2 installfile]$ sudo scl enable devtoolset-8 bash [root@node2 installfile]#
2）测试 gcc版本
[root@node2 installfile]# su hadoop [hadoop@node2 installfile]# gcc --version gcc (GCC) 8.3.1 20190311 (Red Hat 8.3.1-3) Copyright (C) 2018 Free Software Foundation, Inc. This is free software; see the source for copying conditions. There is NO warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
发现执行第1）步命令后，gcc版本更新了。
Redis安装包的下载及解压
下载安装包redis-6.0.8.tar.gz
[hadoop@node2 installfile]# wget https://download.redis.io/releases/redis-6.0.8.tar.gz
解压
[hadoop@node2 installfile]$ tar -zxvf redis-6.0.8.tar.gz -C ~/soft/
进入解压后目录
[hadoop@node2 installfile]$ cd ~/soft/redis-6.0.8/ [hadoop@node2 redis-6.0.8]$
编译
[hadoop@node2 redis-6.0.8]$ make
安装
[hadoop@node2 redis-6.0.8]$ sudo make install
默认安装目录：/usr/local/bin
[hadoop@node2 redis-6.0.8]$ ls /usr/local/bin/ redis-benchmark redis-check-aof redis-check-rdb redis-cli redis-sentinel redis-server
如果想更换安装目录，可使用如下命令
sudo make install PREFIX=/usr/local/redis
这里的操作使用默认的安装目录
配置Redis
拷贝一份redis.conf到其他目录
[hadoop@node2 redis-6.0.8]$ cp redis.conf ~/my_redis.conf
修改my_redis.conf
vim ~/my_redis.conf
修改如下内容：
1）添加在bind 127.0.0.1一行行首添加#，允许外部机器连接访问。
#bind 127.0.0.1
2）protected-mode yes改为no
protected-mode no
3）后台启动设置daemonize no 改成 yes
protected-mode no
4）将 daemonize no 改为 yes，让服务在后台启动
daemonize yes
Redis启动
[hadoop@node2 redis-6.0.8]$ /usr/local/bin/redis-server ~/my_redis.conf [hadoop@node2 redis-6.0.8]$ /usr/local/bin/redis-cli 127.0.0.1:6379> ping PONG 127.0.0.1:6379> exit [hadoop@node2 redis-6.0.8]$
设置环境变量
修改my_env.sh
[hadoop@node2 redis-6.0.8]$ sudo vim /etc/profile.d/my_env.sh
添加如下环境变量
#REDIS export PATH=$PATH:/usr/local/bin
让环境变量生效
[hadoop@node2 redis-6.0.8]$ source /etc/profile
关闭Redis
查看redis进程
[hadoop@node2 redis-6.0.8]$ ps -ef | grep redis hadoop 6335 1 0 00:04 ? 00:00:00 /usr/local/bin/redis-server *:6379 hadoop 6403 1898 0 00:10 pts/0 00:00:00 grep --color=auto redis
Redis关闭
[hadoop@node2 redis-6.0.8]$ redis-cli shutdown [hadoop@node2 redis-6.0.8]$ ps -ef | grep redis hadoop 6406 1898 0 00:12 pts/0 00:00:00 grep --color=auto redis
也可以进入终端后执行shutdown命令关闭
[hadoop@node2 redis-6.0.8]$ redis-server ~/my_redis.conf [hadoop@node2 redis-6.0.8]$ ps -ef | grep redis hadoop 6408 1 0 00:14 ? 00:00:00 redis-server *:6379 hadoop 6414 1898 0 00:14 pts/0 00:00:00 grep --color=auto redis [hadoop@node2 redis-6.0.8]$ redis-cli 127.0.0.1:6379> shutdown not connected> not connected> not connected> quit [hadoop@node2 redis-6.0.8]$ ps -ef | grep redis hadoop 6417 1898 0 00:14 pts/0 00:00:00 grep --color=auto redis
指定端口关闭
[hadoop@node2 redis-6.0.8]$ redis-server ~/my_redis.conf [hadoop@node2 redis-6.0.8]$ ps -ef | grep redis hadoop 6420 1 0 00:17 ? 00:00:00 redis-server *:6379 hadoop 6432 1898 0 00:17 pts/0 00:00:00 grep --color=auto redis [hadoop@node2 redis-6.0.8]$ redis-cli -p 6379 shutdown [hadoop@node2 redis-6.0.8]$ ps -ef | grep redis hadoop 6435 1898 0 00:17 pts/0 00:00:00 grep --color=auto redis
完成！enjoy it!
