在LNMP的环境下其中一条很重要的优化就是安装Redis&＃xff0c;而对于Memcache和Redis的选择的话&＃xff0c;Memcache支持多核多线程&＃xff0c;Redis单线程操作并且只使用单核&＃xff0c;单核下存储数据较小的时候Redis要比Memcache性能更好&＃xff0c;但当数据大于100K时&＃xff0c;Memcache优秀之处便体现出来。
因为大象网是个很小的站点&＃xff0c;所以我便选择了opcache&＃43;Redis&＃xff0c;前者先不说&＃xff0c;因为操作很简单直接修改PHP.INI就可以&＃xff0c;所以这里就简单说下我的腾讯云服务器在LNMP下无法安装Redis的解决方法。
本来服务器的环境是LNMP1.5&＃xff0c;正常情况下&＃xff0c;我们直接进入LNMP1.5的的目录&＃xff0c;执行一条命令就可以正常安装Redis&＃xff0c;如果有其它要做的那就是需要等待就可以了。
但我执行命令后却报错了&＃xff0c;我没有保存&＃xff0c;但我找到了别人的错误显示结果&＃xff0c;虽然版本不太一样&＃xff0c;但是显示的错误信息却是一样的。

如果你也遇到这个问题&＃xff0c;那么你是很幸运的&＃xff0c;因为解决起来很简单。这个问题是因为无法下载Redis所以引起的错误&＃xff0c;我们修改一下该服务器的DNS就好了&＃xff0c;将第一个DNS服务器地址修改为114.114.114.114&＃xff0c;第二个DNS服务器地址是否修改并不影响。
vi /etc/resolv.conf
nameserver 114.114.114.114
nameserver 8.8.8.8

修改完成后&＃xff0c;我们再执行安装Redis命令的话&＃xff0c;一般就不会出现问题了&＃xff0c;祝你好运哈。
我在整个过程中还是遇到了很多坑&＃xff0c;在报错之后我认为是脚本的问题&＃xff0c;其实安装Redis并且在下载的它的时候会出现一个Redis的URL链接&＃xff0c;我还特意把这个链接复制到本地PC上下载测试却是正常&＃xff0c;这就能证明并不是被墙的原因。
由于我对Linux的了解并不多&＃xff0c;所以几番尝试之后没有搞定&＃xff0c;就重装了&＃xff0c;但坑并没有结束&＃xff0c;比如如下报错。

skying查找资料更换下载地址可以解决&＃xff0c;但是还是302跳转到上面那个IP上&＃xff0c;最后便安装了LNMP1.6的完整版&＃xff0c;当时看了看时间&＃xff0c;好像去年还是前年就是在五一前后出的问题&＃xff0c;好吧&＃xff0c;具体命令如下。
wget https://upyun.vpser.net/lnmp/lnmp1.6-full.tar.gz-cO lnmp1.6-full.tar.gz && tar zxf lnmp1.6-full.tar.gz && cd lnmp1.6-full && ./install.sh lnmp
