Windows下Redis中RedisQFork位置调整

Posted 2020-08-11

RedisQFork_4328.dat

启动windows版本的Redis会在C盘创建一个RedisQFork打头的文件，改变存放位置的办法：

在redis.windows.conf下更改参数heapdir为./，表示是在当前目录

# The Linux version of Redis relies on the system call fork() to perform
# point-in-time snapshots of the heap. In addition to the AOF and RDB backup
# mechanism, the master-slave synchronization and clustering features are 
# dependent on this behavior of fork(). In order for the Windows version to 
# perform like the Linux version we had to simulate this aspect of fork().
# Doing so meant moving the Redis heap into a memory mapped file that can
# be shared with a child process. 
#
# *** There must be disk space available for this file in order for Redis 
# to launch. *** The default configuration places this file in the local 
# appdata directory. If you wish to move this file to another local disk,
# use the heapdir flag as described below.
#
# The maxheap flag controls the maximum size of this memory mapped file,
# as well as the total usable space for the Redis heap. Running Redis
# without either maxheap or maxmemory will result in a memory mapped file 
# being created that is equal to the size of physical memory. During 
# fork() operations the total page file commit will max out at around:
#
#    (size of physical memory) + (2 * size of maxheap)
#
# For instance, on a machine with 8GB of physical RAM, the max page file 
# commit with the default maxheap size will be (8)+(2*8) GB , or 24GB. The
# default page file sizing of Windows will allow for this without having 
# to reconfigure the system. Larger heap sizes are possible, but the maximum
# page file size will have to be increased accordingly.
# 
# The Redis heap must be larger than the value specified by the maxmemory 
# flag, as the heap allocator has its own memory requirements and 
# fragmentation of the heap is inevitable. If only the maxmemory flag is 
# specified, maxheap will be set at 1.5*maxmemory. If the maxheap flag is 
# specified along with maxmemory, the maxheap flag will be automatically 
# increased if it is smaller than 1.5*maxmemory. 
#  
# maxheap <bytes>

# The heap memory mapped file must reside on a local path for heap sharing 
# between processes to work. A UNC path will not suffice here. For maximum 
# performance this should be located on the fastest local drive available.
# This value defaults to the local application data folder(e.g.,
# "%USERPROFILE%\AppData\Local"). Since this file can be very large, you
# may wish to place this on a drive other than the one the operating system  
# is installed on.
#
# Note that you must specify a directory here, not a file name.
# heapdir <directory path(absolute or relative)>
heapdir ./

启动redis服务器：run.bat

redis-server.exe  redis.windows.conf

 

Redis是可以安装成windows服务的，开机自启动

redis-server --service-install redis.windows.conf

但是安装好之后，Redis并没有启动，启动命令如下：

redis-server --service-start
停止命令：

redis-server --service-stop
还可以安装多个实例

redis-server --service-install –service-name redisService1 –port 10001
redis-server --service-start –service-name redisService1
redis-server --service-install –service-name redisService2 –port 10002
redis-server --service-start –service-name redisService2
redis-server --service-install –service-name redisService3 –port 10003
redis-server --service-start –service-name redisService3
卸载命令：

redis-server --service-uninstall
最后提示一下：2.8版本的不支持32位系统，32位系统要去下载2.6版本的。2.6版本的无法像上面一样方便的部署，它提供一个叫RedisWatcher的程序来运行redis server，Redis停止后会自动重启。

另外推荐一个Redis可视化管理工具：Redis Desktop Manager，官网的下载地址被墙了，可以在我的网盘下载 v0.7.6版
