【问题描述】：

cd /tmp

wget http://www-us.apache.org/dist/lucene/solr/6.2.0/solr-6.2.0.tgz

tar xzf solr-6.2.0.tgz solr-6.2.0/bin/install_solr_service.sh --strip-components=2

[root@ns52132 tmp]# sudo ./install_solr_service.sh solr-6.2.0.tgz

id: solr: no such user
Creating new user: solr
adduser: group '--disabled-password' does not exist

Extracting solr-6.2.0.tgz to /opt


Installing symlink /opt/solr -> /opt/solr-6.2.0 ...


Installing /etc/init.d/solr script ...


/etc/default/solr.in.sh already exist. Skipping install ...


/var/solr/data/solr.xml already exists. Skipping install ...


/var/solr/log4j.properties already exists. Skipping install ...

chown: invalid spec: ‘solr:’

许多网站都提到了相同的步骤，我关注的是https://www.howtoforge.com/tutorial/how-to-install-and-configure-solr-on-ubuntu-1604/

【解决方案1】：

编辑install_solr_service.sh，找到下面一行

adduser --system --shell /bin/bash --group --disabled-password --home "$SOLR_VAR_DIR" "$SOLR_USER"

并替换为

adduser --system --shell /bin/bash --home "$SOLR_VAR_DIR" "$SOLR_USER"

根据man page for adduser：

The default is to disable the password. 因此，在更改命令后删除--disabled-password 应该不会有任何影响。

不确定删除--group 的影响，但我认为这是选择默认用户组，这是现在的默认行为。
