Redis运维常用
以下是给自己看的。。。
yum -y install gcc
jemalloc/jemalloc.h：没有那个文件或目录
make MALLOC=libc
systemctl status firewalld
systemctl stop firewalld
systemctl stop iptables
service iptables status
service iptables stop
cluster nodes
redis-trib.rb check 10.1.241.47:6379 看是否全覆盖

只有一个节点
Not all 16384 slots are covered by nodes.
1. fix
./redis-cli --cluster fix 10.10.130.161:7001 x 6
./redis-cli --cluster fix 10.1.241.47:6379
2. create
3. aof , rdb 先备份后删除
4. 重启
5. 再create
将节点都加进去
