CentOS 7.7系统安装Redis 6.0.3
<h1 id="前提操作">前提操作</h1><p>避免出现如下的错误</p>
<pre><code>yum -y install gcc tcl
yum -y install centos-release-scl
yum -y install devtoolset-9-gcc devtoolset-9-gcc-c++ devtoolset-9-binutils
echo "source /opt/rh/devtoolset-9/enable" >> /etc/profile

<pre><code>tar -zxv -f redis-6.0.3.tar.gz -C /usr/local/
cd redis-6.0.3
make MALLOC=libc
make test
</code></pre>
<p>在redis根目录下执行make install命令，此命令会将redis/src下的一些脚本拷贝到/usr/local/bin/目录下，<br>
因为/usr/local/bin/目录已经在path环境变量中配置了，所以执行此命令的目的是在任何目录下都可以直接启动停止redis。</p>

<p>解决办法：<br>
查看gcc版本是否在5.3以上，CentOS7默认安装4.8.5。<br>
升级gcc到5.3以上版本，升级到gcc 9</p>
<pre><code>gcc -v
