Shell Redis单机版本部署

Reids编译安装出错

make PREFIX=/usr/local/redis install

[root@mmjredis redis-6.0.1]# make PREFIX=/usr/local/redis install

出现错误如下：

 解决办法：

# 查看gcc版本是否在5.3以上，centos7.6默认安装4.8.5
gcc -v
# 升级gcc到5.3及以上,如下：
升级到gcc 9.3：
yum -y install centos-release-scl
yum -y install devtoolset-9-gcc devtoolset-9-gcc-c++ devtoolset-9-binutils
scl enable devtoolset-9 bash
需要注意的是scl命令启用只是临时的，退出shell或重启就会恢复原系统gcc版本。
如果要长期使用gcc 9.3的话：
 
echo "source /opt/rh/devtoolset-9/enable" >>/etc/profile
这样退出shell重新打开就是新版的gcc了
以下其他版本同理，修改devtoolset版本号即可。

 Reids安装脚本

要使用redis安装脚本安装redis先要手动将gcc升级，因为执行scl enable devtoolset-9 bash升级会跳出shell脚本，所以先要手动升级，这一点比较麻烦！
gcc -v
yum install  centos-release-scl  devtoolset-9-gcc devtoolset-9-gcc-c++ devtoolset-9-binutils  -y
echo "source /opt/rh/devtoolset-9/enable" >>/etc/profile
scl enable devtoolset-9 bash
