Complete!Install Elasticsearch 7.x using RPM package
To manually install Elasticsearch 7.x on Fedora 30 sing RPM package, download the RPM package.
wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.1.1-x86_64.rpmNext, download the checksum for verifying the integrity of the RPM package.
wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.1.1-x86_64.rpm.sha512
Run the integrity check by comparing the checksums. Before that, install perl-Digest-SHA -y which provides shasum for checksum comparison.
dnf install perl-Digest-SHA -y
shasum -a 512 -c elasticsearch-7.1.1-x86_64.rpm.sha512If all is well, then you will get an OK output.
elasticsearch-7.1.1-x86_64.rpm: OKNext, Install Elasticsearch 7.x on Fedora 30

...You need to check if some Machine Learning X-pack controller Module libraries are missing. Hence, run the command below to verify this.
ldd /usr/share/elasticsearch/modules/x-pack-ml/platform/linux-x86_64/bin/controller | grep "not found"
libcrypt.so.1 => not found
libcrypt.so.1 => not found
libcrypt.so.1 => not foundTherefore, to fix the issue, install the missing libraries. For this case, this libraries can sorted by install the libxcrypt-compat.
dnf install libxcrypt-compatVerify the missing libraries again.
ldd /usr/share/elasticsearch/modules/x-pack-ml/platform/linux-x86_64/bin/controller | grep "not found"Next, restart Elasticsearch and verify that it is actually running by executing the command below
curl -XGET localhost:9200
{
"name" : "pdns.example.com",
"cluster_name" : "elasticsearch",
"cluster_uuid" : "VmhyYe9KTnud1y4voHKdrg",
"version" : {
"number" : "7.1.1",
"build_flavor" : "default",
"build_type" : "rpm",

"minimum_wire_compatibility_version" : "6.8.0",
"minimum_index_compatibility_version" : "6.0.0-beta1"
},
"tagline" : "You Know, for Search"
}Another Solution to fix this issue is by disabling the Machine learning capability of Elasticsearch by appending the line xpack.ml.enabled: false to the Elasticsearch configuration file.
echo "xpack.ml.enabled: false" >> /etc/elasticsearch/elasticsearch.ymlIf FirewallD is running, you need to open tcp port 9200 on it.
sudo firewall-cmd --add-port=9200/tcp --permanent
sudo firewall-cmd --reloadGreat, that is all it takes to install Elasticsearch 7 on Fedora 30.
