CentOS7中编译安装redis5.0 环境介绍CentOS7 (未安装Development Tools)下载Redis5.0-rc3 wget -O redis-5.0-rc3.tar.gz https://github.com/antirez/redis/archive/5.0-rc3.tar.gz解压redis tar -zxvf redis-5.0-rc3.tar.gz -C /usr/local编译并安装 cd /usr/local/redis-5.0-rc3 make此时会出错： compilation terminated. make[1]: *** [adlist.o] Error 1 make[1]: Leaving directory `/usr/local/redis-5.0-rc3/src' make: *** [all] Error 2安装Development Tools yum groupinstall 'Development Tools'再次执行，还会报错 make cd src && make all make[1]: Entering directory `/usr/local/redis-5.0-rc3/src' CC adlist.o In file included from adlist.c:34:0: zmalloc.h:50:31: fatal error: jemalloc/jemalloc.h: No such file or directory #include <jemalloc/jemalloc.h> ^ compilation terminated. make[1]: *** [adlist.o] Error 1 make[1]: Leaving directory `/usr/local/redis-5.0-rc3/src' make: *** [all] Error 2最后解决方案如下： cd /usr/local/redis-5.0-rc3/deps; make hiredis lua jemalloc linenoise编译完成后再次在/usr/local/redis-5.0-rc3中执行make命令 cd /usr/local/redis-5.0-rc3 make出现如下即编译成功 Hint: It's a good idea to run 'make test' ? make[1]: Leaving directory `/usr/local/redis-5.0-rc3/src'然后在/usr/local/redis-5.0-rc3/src中执行安装命令： cd /usr/local/redis-5.0-rc3/src make install会出现如下日志信息 Hint: It's a good idea to run 'make test' ? INSTALL install INSTALL install INSTALL install INSTALL install INSTALL install修改redis.conf配置文件 vim /usr/local/redis-5.0-rc3/redis.conf只需要调整如下几个即可 protected-mode no # 关闭保护模式 daemonize yes # 守护进程模式开启启动redis5.0 /usr/local/redis-5.0-rc3/src/redis-server /usr/local/redis-5.0-rc3/redis.conf其实我们在执行make install的时候会将src下面的几个命令复制到/usr/local/bin/下面去，也可以执行如下命令启动redis5.0 /usr/local/bin/redis-server /usr/local/redis-5.0-rc3/redis.conf检查端口 netstat -ltnp |grep 6379如果有端口监听，说明redis已经启动成功。连接下试试 redis-cli 127.0.0.1:6379> info # Server redis_version:4.9.103 redis_git_sha1:00000000 redis_git_dirty:0 redis_build_id:207f31cf830c081e redis_mode:standalone os:Linux 3.10.0-693.17.1.el7.x86_64 x86_64 arch_bits:64 multiplexing_api:epoll atomicvar_api:atomic-builtin gcc_version:4.8.5 process_id:20361 run_id:4835668974ad86f1db9b3c8b98e02be1a87a7b9b tcp_port:6379 uptime_in_seconds:689 uptime_in_days:0 hz:10 lru_clock:3944003 为什么能在任意目录执行redis-cli命令呢，因为redis-cli命令在/usr/local/bin目录里面，而该目录又配置在PATH中，所以你可以向执行ls、mkdir等命令的方式去执行redis-cli或者redis-server等命令。一般我们在安装完redis后就会将其安装包给删除，那么我们只需要将redis.conf配置文件移动的其他目录，比如：/etc/redis/redis.conf中，具体位置在哪请按照自己的习惯或者规范放置即可。

PHP实现无顺序连贯操作 想必大家都用过tp的Db类吧,连贯操作是不是很酷实现很简单不需要用到__call方法简单分析一下tp框架的Db类 Db::name('user')->where('id', 1)->find()以上这行代码 首先调用name方法不过是静态的最后返回当前对象继续调用其他方法重点:结束时是return当前对象,静态方法使用 return new self() 返回,非静态使用 return $this;下面举一个小例子: <?php /** * @author anderyly * @email anderyly@sina.com * @link https://blog.aaayun.cc * @copyright Copyright (c) 2019 */ namespace ay; class Test { public static $name; public static function set($name) { self::$name = $name; return new self(); } public function add() { self::$name = "an" . self::$name; return $this; } public function get() { return self::$name; } }调用Test类 $name = Test::set('deryly')->add()->get(); echo $name; // 输出 anderyly
