Neo4j圖數據庫配置文件詳解

1. For more details and a complete list of settings, please see https://neo4j.com/docs/operations-manual/current/reference/configuration-settings/
2.  
    
3.  
   # 若是想自定義neo4j數據庫數據的存儲路徑，要同時修改dbms.active_database 和 dbms.directories.data 兩項配置，
4.  
   # 修改配置後，數據會存放在${dbms.directories.data}/databases/${dbms.active_database} 目錄下
5.  
   # 安裝的數據庫的名稱，默認使用${NEO4J_HOME}/data/databases/graph.db目錄
6.  
   # The name of the database to mount
7.  
   #dbms.active_database=graph.db
8.  
    
9.  
   #安裝Neo4j數據庫的各個配置路徑，默認使用$NEO4J_HOME下的路徑
10.  
    #Paths of directories in the installation.
11.  
    # 數據路徑
12.  
    #dbms.directories.data=data
13.  
    # 插件路徑
14.  
    #dbms.directories.plugins=plugins
15.  
    #dbms.directories.certificates=certificates 證書路徑

19.  
     
20.  
    #默認狀況下想load csv文件，只能把csv文件放到${NEO4J_HOME}/import目錄下，把下面的#刪除後，能夠在load csv時使用絕對路徑，這樣可能不安全
21.  
    #This setting constrains all `LOAD CSV` import files to be under the `import` directory. Remove or comment it out to allow files to be loaded from anywhere in the filesystem; this introduces possible security problems. See the `LOAD CSV` section of the manual for details.
22.  
    #此設置將全部「LOAD CSV」導入文件限制在`import`目錄下。刪除註釋容許從文件系統的任何地方加載文件;這引入了可能的安全問題。
23.  
    dbms .directories.import=import
24.  
     
25.  
    #把下面這行的#刪掉後，鏈接neo4j數據庫時就不用輸密碼了
26.  
    #Whether requests to Neo4j are authenticated. 是否對Neo4j的請求進行了身份驗證。
27.  
    #To disable authentication, uncomment this line 要禁用身份驗證，請取消註釋此行。
28.

32.  
     
33.  
    #Java Heap Size: by default the Java heap size is dynamically calculated based on available system resources. Java堆大小：默認狀況下，Java堆大小是動態地根據可用的系統資源計算。
34.  
    #Uncomment these lines to set specific initial and maximum heap size. 取消註釋這些行以設置特定的初始值和最大值
35.  
    #dbms.memory.heap.initial_size=512m
36.  
    #dbms.memory.heap.max_size=512m
37.  
     
38.  
    #The amount of memory to use for mapping the store files, in bytes (or kilobytes with the 'k' suffix, megabytes with 'm' and gigabytes with 'g'). 用於映射存儲文件的內存量（以字節爲單位）千字節帶有'k'後綴，兆字節帶有'm'，千兆字節帶有'g'）。
39.  
    #If Neo4j is running on a dedicated server, then it is generally recommended to leave about 2-4 gigabytes for the operating system, give the JVM enough heap to hold all your transaction state and query context, and then leave the rest for the page cache. 若是Neo4j在專用服務器上運行，那麼一般建議爲操做系統保留大約2-4千兆字節，爲JVM提供足夠的堆來保存全部的事務狀態和查詢上下文，而後保留其他的頁面緩存 。
40.  
    #The default page cache memory assumes the machine is dedicated to running Neo4j, and is heuristically set to 50% of RAM minus the max Java heap size. 默認頁面緩存存儲器假定機器專用於運行Neo4j，而且試探性地設置爲RAM的50％減去最大Java堆大小。
41.  
    #dbms.memory.pagecache.size=10g

43.  
     
44.  
    ### Network connector configuration
45.  
     
46.  
    #With default configuration Neo4j only accepts local connections. Neo4j默認只接受本地鏈接(localhost)
47.  
    #To accept non-local connections, uncomment this line: 要接受非本地鏈接，請取消註釋此行
48.  
    dbms .connectors.default_listen_address=0.0.0.0 (這是刪除#後的配置，能夠經過ip訪問)
49.  
     
50.  
    #You can also choose a specific network interface, and configure a non-default port for each connector, by setting their individual listen_address. 還能夠選擇特定的網絡接口，並配置非默認值端口，設置它們各自的listen_address
51.  
     
52.  
    #The address at which this server can be reached by its clients. This may be the server's IP address or DNS name, or it may be the address of a reverse proxy which sits in front of the server. This setting may be overridden for individual connectors below. 客戶端能夠訪問此服務器的地址。這能夠是服務器的IP地址或DNS名稱，或者能夠是位於服務器前面的反向代理的地址。此設置可能會覆蓋如下各個鏈接器。
53.  
    #dbms.connectors.default_advertised_address=localhost
54.  
     
55.  
    #You can also choose a specific advertised hostname or IP address, and configure an advertised port for each connector, by setting their individual advertised_address. 您還能夠選擇特定廣播主機名或IP地址，
56.  
    爲每一個鏈接器配置通告的端口，經過設置它們獨特的advertised_address。

     #Make sure that `initmemory` is not only allocated, but committed to the process, before starting the database. This reduces memory fragmentation, increasing the effectiveness of transparent huge pages. It also reduces the possibility of seeing performance drop due to heap-growing GC events, where a decrease in available page cache leads to an increase in mean IO response time. Try reducing the heap memory, if this flag degrades performance. 確保在啓動數據庫以前，「initmemory」不只被分配，並且被提交到進程。這減小了內存碎片，增長了透明大頁面的有效性。它還減小了因爲堆增加的GC事件而致使性能降低的可能性，其中可用頁面緩存的減小致使平均IO響應時間的增長。若是此標誌下降性能，請減小堆內存。
