#創(chuàng)建elsearch用戶，Elasticsearch不支持root用戶運(yùn)行 
useradd elsearch
 
#解壓安裝包 
tar -xvf elasticsearch-8.3.3-linux-x86_64.tar.gz -C es/
 
#修改配置文件 
vim conf/elasticsearch.yml 
network.host: 0.0.0.0 #設(shè)置ip地址，任意網(wǎng)絡(luò)均可訪問
 
#說(shuō)明：在Elasticsearch中如果，network.host不是localhost或者127.0.0.1的話，就會(huì)認(rèn)為是生產(chǎn)環(huán)境， 會(huì)對(duì)環(huán)境的要求比較高，我們的測(cè)試環(huán)境不一定能夠滿足，一般情況下需要修改2處配置，如下： 
#1：修改jvm啟動(dòng)參數(shù) 
vim conf/jvm.options 
-Xms128m  #根據(jù)自己機(jī)器情況修改 
-Xmx128m 
#2：一個(gè)進(jìn)程在VMAs(虛擬內(nèi)存區(qū)域)創(chuàng)建內(nèi)存映射最大數(shù)量 
vim /etc/sysctl.conf 
vm.max_map_count=655360 
sysctl -p #配置生效
 
#啟動(dòng)ES服務(wù) 
su - elsearch 
cd bin 
./elasticsearch 或 ./elasticsearch -d #后臺(tái)啟動(dòng)
 
#通過(guò)訪問進(jìn)行測(cè)試，看到如下信息，就說(shuō)明ES啟動(dòng)成功了

[1]: max file descriptors [4096] for elasticsearch process is too low, increase to at least [65536] 
#解決：切換到root用戶，編輯limits.conf 添加類似如下內(nèi)容

添加如下內(nèi)容:

#解決：切換到root用戶，進(jìn)入limits.d目錄下修改配置文件。 
vi /etc/security/limits.d/90-nproc.conf 
#修改如下內(nèi)容：

添加：
