redis 5 安装
wget -c http://download.redis.io/releases/redis-5.0.5.tar.gz
redis_install_dir=/home/apps/redis
redis_ver=5.0.5
THREAD=4
tar xzf redis-${redis_ver}.tar.gz
pushd redis-${redis_ver} > /dev/null
make -j ${THREAD}
make PREFIX=/home/apps/redis #here
make distclean
#cd src && make install #这个才行 特别是cluster ? 2019年 8月16日 星期五 23时29分41秒 CST
make install PREFIX=/home/apps/redis # make install #这个有时没有创建出目录来呀
#这个我没做 根本没用 哈哈
#复制rb 或者放到安装的bin目录 然后再加path
#cp /opt/redis-5.0.0/src/redis-trib.rb /usr/local/bin
echo 'export PATH=/home/apps/redis/bin/:$PATH' >> /etc/profile && source /etc/profile
NOTE
redis5 用redis-cli创建整个redis集群(redis5以前的版本集群是依靠ruby脚本redis-trib.rb实现

添加redis集群密码
方式一：修改所有Redis集群中的redis.conf文件加入
# NOTE 还是这个办法好 不然可能有些 没加载到配置文件去呢 masterauth passwd123 requirepass passwd123 说明：这种方式需要重新启动各节点
方式二：进入各个实例进行设置 就是所有节点：
redis-cli -c -h 10.3.10.141 -p 7001 #好像不能一起执行 config set masterauth 36DbRGvv config set requirepass 36DbRGvv auth 36DbRGvv config rewrite 添加redis集群密码 一开始忘记加-c 导致 143 两个都加不上了 redis本身的密码这样就有了 -a 后 再执行命令就再 auth ， 而如果是进入后 auth password 要每次 都再验证一下密码 麻烦
