WordPress + Redis Object Cache

处理遇到如 ”/var/redis/run/redis_6379.pid exists, process is already running or crashed“的问题

先命令：service redis start

遇到 ”/var/redis/run/redis_6379.pid exists, process is already running or crashed“

引起这类问题一般都是强制关掉电源或断电造成的，也是没等linux正常关机

科学的处理办法2种：

• 可用安装文件启动 redis-server /etc/redis/6379.conf

• shutdown -r now软重启让系统自动恢复下就行了
