redis笔记

gcc没装：

yum -y install gcc gcc-c++

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo

yum makecache

rm -fr  /etc/yum.repos.d/*

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo

yum makecache

make clean

make MALLOC=libc

说明： redis-3.2.8版本不需要make，不需要make test,不需要make install

            直接把src目录copy走就能用,这个就是make，只不过指定用libcmake

登陆进去之后不能用，是redis数据持久化问题

(error) MISCONF Redis is configured to save RDB snapshots, but is currently not able to persist on disk.

今天运行Redis时发生错误，错误信息如下：

(error) MISCONF Redis is configured to save RDB snapshots, but is currently not able to persist on disk. Commands that may modify the data set are disabled. Please check Redis logs for details about the error.

Redis被配置为保存数据库快照，但它目前不能持久化到硬盘。用来修改集合数据的命令不能用。请查看Redis日志的详细错误信息。

原因：

强制关闭Redis快照导致不能持久化。

解决方案：

运行config set stop-writes-on-bgsave-error no　命令后，关闭配置项stop-writes-on-bgsave-error解决该问题。

root@ubuntu:/usr/local/redis/bin# ./redis-cli

127.0.0.1:6379> config set stop-writes-on-bgsave-error no

OK

127.0.0.1:6379> lpush myColour "red"
