下载地址，本案例下载的是jfrog-artifactory-jcr-7.59.11-linux.tar.gz：
https://releases.jfrog.io/artifactory/bintray-artifactory/org/artifactory/jcr/jfrog-artifactory-jcr/
2、解压下载下来的压缩包
tar zxf jfrog-artifactory-jcr-7.59.11-linux.tar.gz
解压出来的是文件夹 artifactory-jcr-7.59.11
3、修改配置，连接 postgresql数据库
注意：数据库一定要用干净的新建的数据库，否则启动服务会报错！
从 /home/zengyanhui/jfrog/artifactory/artifactory-jcr-7.59.11/var/etc目录下将 system.basic-template.yaml 复制到新文件 system.yaml
cp system.basic-template.yaml system.yaml修改 /home/zengyanhui/jfrog/artifactory/artifactory-jcr-7.59.11/var/etc/system.yaml文件，添加 以下内容：
## Database Configurationdatabase:## To run Artifactory with any database other than PostgreSQL allowNonPostgresql set to true.#allowNonPostgresql: false## One of mysql, oracle, mssql, postgresql, mariadb## Default Embedded derby## Example for postgresqltype: po
