journalctl more ways to check if Elasticsearch is running
You can test that the Elasticsearch node is running by sending an HTTP request to port 9200 on localhost:
Curl-xget ' Localhost:9200/?pretty '
We can get the following echo:
{
"name": "De-lrno",
"cluster_name": "Elasticsearch",
"Cluster_uuid": "Dejzplwhqqk5ugitxr8jja",
" Version ": {
" number ":" 5.1.1 ",
" Build_hash ":" 5395e21 "
card does not have this ability, these need to use CPU software decoding, then the computer run up more laborious.
A lot of laptops under 3500 yuan use integrated graphics, and the most common 2 integrated graphics are: Intel GMA 4500MHD and ATI Mobility Radeon HD3200. The latter performance is superior to the former.
More than 3500 yuan notebook computers are basically using a stand-alone graphics card.
Take Lenovo and Dell computers for example:
radeon 8500 is indeed not flattering. When the anti-sawtooth function is enabled, the performance will still decrease. Therefore, radeon 8500 automatically reduces the level of texture details after enabling the anti-aliasing function, thus reducing the throughput of the memory bandwidth. However, the texture quality becomes very bad. (Full screen anti-sawtooth is not enabled on 7 and 8, smoothvision 6x is
opinion, d3d11 has to run on the hardware of d3d11, but the hardware of d3d11 has not yet been popularized. This will affect the running of klayge on the hardware of d3d10. My answers to these questions are usually very cold. "Why did you add comments if you don't know d3d11 ".
One of the most basic knowledge of d3d11 is the feature level. In fact, this is not a new invention. It was proposed at the time of d3d 10.1, but because the usage of d3d 10.1 is too small, it is ignored directly. Featu
After Ubuntu is upgraded from 9.10 to 10.04, it is found that the screen is full-screen and transient striped. After some tossing, it was found that it was a problem with KMS. Ubuntu10.04 enabled KMS on Kernel 2.6.32 by default, so this problem occurs, and everything will be normal after 2.6.31 is selected as the boot option. After searching, ubuntuwiki has an introduction. After KMS is disabled, my video card is ninehills @ localhost :~ $ Lspci-nn |

What about the new MacBook Pro solo dominance?
The MacBook Pro product update, in addition to the appearance of the adjustment (more frivolous), the configuration is also upgraded, of which "low match" (13-inch also got 11488 yuan) the nuclear screen is Iris 540/550, while the high match is AMD Radeon Pro 450 Graphics (13 inch) and AMD Radeon Pro 455/460 Graphics Card (15 inch).

Elasticsearch is a distributed RESTful style search and data analysis engine. The biggest difference between the elasticsearch of personal understanding and the traditional relational database is that it can be structured search, full-text retrieval and data analysis. This article briefly describes how to complete the Elasticsearch RESTful API functionality with the Curl command in a Linux environment. A Elasticsearch request, like any HTTP request, consists of several identical parts:
Curl-x
/data
path.logs:/data/elk/logs
network.host:0.0.0.0
http.port:9200
Discovery.zen.ping.unicast.hosts: ["Es1", "Es2"]
bootstrap.memory_lock:false
Bootstrap.system_call_ Filter:false
(because CENTOS6 does not support Seccomp, and ES default bootstrap.system_call_filter is true for detection, which causes the detection to fail, which directly causes ES to fail to start. )
