**Docker安装redis**
|
||||||
|
**1.首先下载redis镜像:**
|
||||||
|
docker pull redis
|
||||||
|
**2.然后创建一个文件夹用来存放redis的配置文件、数据等(也就是所谓的挂载目录,作用就是将此目录中的文件或文件夹覆盖掉容器内部的文件或文件夹)**
|
||||||
|
**3.在上面创建的目录下使用命令启动redis容器**
|
||||||
|
docker run -d -p 6379:6379 -v $PWD/conf/redis.conf:/usr/local/etc/redis/redis.conf -v $PWD/data:/data --name docker-redis docker.io/redis redis-server /usr/local/etc/redis/redis.conf --appendonly yes
|
||||||
|
**解释一下上面命令的意义:**
|
||||||
|
-d:表示后台运行,不加-d执行上面的命令你就会看到redis启动的日志信息了
|
||||||
|
-p:表示端口映射,冒号左面的是我们的宿主机的端口,也就是我们虚拟机的端口,而右侧则表示的是mysql容器内的端口
|
||||||
|
--name:是我们给redis容器取的名字
|
||||||
|
-v:表示挂载路径,$PWD表示当前目录下,冒号左面的表示我们宿主机的挂载目录,也就是我们虚拟机所在的文件路径,冒号右边则表是的是redis容器在容器内部的路径,上面的命令我分别挂载了redis.conf(redis的配置文件),如需使用配置文件的方式启动redis,这里则需要加上,还有redis存放数据所在的目录
|
||||||
|
--appendonly yes:表示redis开启持久化策略

其中:

V为观测值的残差;

P为观测值的权;

n-f为观测值的总数减去未知数个数。

RMS表明了观测值的质量。RMS越小,观测值质量越好;

反之,表明观测值质量越差。它不受观测条件(如卫星分布好坏)的影响。

依照数理统计的理论,观测值误差落在1.96 倍RMS 的范围内的概率

1、 同步闭合环
|
||||||
|
同步环闭合差是由同步观测基线所组成的闭合环的闭合差。
|
||||||
|
由于同步观测基线间具有一定的内在联系,从而使得同步环闭合差在
|
||||||
|
理论上应总是为0 的。如果同步环闭合差超限,则说明组成同步环的基线
|
||||||
|
中至少存在一条基线向量是错误的。但反过来,如果同步环闭合差没有超
|
||||||
|
限,只能认为静态基线在质量上,绝大部分情况下是合格的,还不能说明
|
||||||
|
组成同步环的所有基线在质量上绝对合格。
|
||||||
|
2、异步闭合环
|
||||||
|
不是完全由同步观测基线所组成的闭合环称为异步环。异步环的闭合
|
||||||
|
差称为异步环闭合差。
|
||||||
|
当异步环闭合差满足限差要求时,则表明组成异步环的基线向量的质
|
||||||
|
量是合格的。当异步环闭合差不满足限差要求时,则表明组成异步环的基
|
||||||
|
线向量中至少有一条基线向量的质量不合格。要确定出哪些基线向量的质
|
||||||
|
量不合格可以通过多个相邻的异步环或重复基线来进行。
|
||||||
|
3、重复基线

不同观测时段对相同的两个测站间的观测结果就是所谓重复基线。这

||||||

些观测结果之间的差异就是重复基线较差。
