CentOS 7 安装配置redis

1. 获取资源
   wget https://download.redis.io/releases/redis-6.0.8.tar.gz
2. 解压
   tar -zxvf redis-6.0.8.tar.gz
3. 安装
   cd redis-6.0.8
make
cd src
make install PREFIX=/usr/local/redis
4. 移动配置文件到安装目录
   cd ../
mkdir /usr/local/redis/etc
mv redis.conf /usr/local/redis/etc
5. 修改配置文件，vim /usr/local/redis/etc/redis.conf ，支持台启动和远程连接
   daemonize yes
protected-mode no
bind 0.0.0.0
6. 拷贝启动脚本至 /usr/local/bin目录
   cp /usr/local/redis/bin/redis-server /usr/local/bin
cp /usr/local/redis/bin/redis-cli /usr/local/bin
7. 启动
   redis-server /usr/local/redis/etc/redis.conf
8. 启动客户端
   redis-cli
9. 设置密码
   config set requirepass ****
10. 停止
    pkill redis

问题：6.x以后的版本安装时，可能会碰到如下问题
报错server.c:xxxx:xx: error: ‘xxxxxxxx’ has no member named ‘xxxxx’

……

         if (server.sofd > 0)

原因：查看gcc的版本是否在 5.3以上，centos7默认是4.8.5.我这里的就是4.8.5
gcc -v
解决方案：

yum -y install centos-release-scl
yum -y install devtoolset-9-gcc devtoolset-9-gcc-c++ devtoolset-9-binutils

scl enable devtoolset-9 bash  #scl命令启用只是临时的
echo "source /opt/rh/devtoolset-9/enable" >>/etc/profile  #永久生效
