linux下安装redis7.0.0 （集群）
上传安装包并解压
bash
cd /opt/redis-7.0.0
yum -y install gcc
//需要有gcc环境 可能需要连接外网 编译1分钟左右
make && make install
//默认安装/usr/local/bin

# So for instance if you have a four cores boxes, try to use 2 or 3 I/O
# threads, if you have a 8 cores, try to use 6 threads. In order to
# enable I/O threads use the following configuration directive:
# io-threads 4
# Setting io-threads to 1 will just use the main thread as usual.
# When I/O threads are enabled, we only use threads for writes, that is
# to thread the write(2) syscall and transfer the client buffers to the
# socket. However it is also possible to enable threading of reads and
# protocol parsing using the following configuration directive, by setting
# it to yes:
# io-threads-do-reads no
