Install software through the YUM source​

This section uses Centos7.9 as an example to show how to install the IvorySQL database. Here is the simplest YUM source installation.

1.1 Installing the YUM Source​

Download address: https://yum.highgo.ca/ivorysql.html

Click "DOWNLOAD REPO RPM" to DOWNLOAD ivorysqL-release-1.0-1.noarch. RPM and upload it to Centos7.9:

Or use wget on Centos7 to download:

wget https://yum.highgo.ca/dists/ivorysql-rpms/repo/ivorysql-release-1.0-1.noarch.rpm

Install ivorysql - release - 1.0-1. Noarch. RPM:

rpm -ivh ivorysql-release-1.0-1.noarch.rpm

After installation, will create the YUM source configuration file: / etc/yum.repos. d/ivorysql.repo.

Search to view related installation packages:

yum search ivorysql

The search results are described in Table 1:

Table 1 Description of YUM sources

Note: 1, 2, 5, 10 are required for RPM package installation, hyperlinks can be downloaded separately.

1.2 installation IVORYSQL​

To install the database service, install ivorysQL1-Server.

Run the following command in the user root session:

yum install -y ivorysql1-server

Installation List:

ivorysql1-server.x86_64 0:1.2-1.rhel7

Dependent installation:

• ivorysql1.x86_64 0:1.2-1.rhel7 ivorysql1-contrib.x86_64 0:1.2-1.rhel7

• ivorysql1-libs.x86_64 0:1.2-1.rhel7 libicu.x86_64 0:50.2-4.el7_7

• libtirpc.x86_64 0:0.2.4-0.16.el7 libxslt.x86_64 0:1.1.28-6.el7

• python3.x86_64 0:3.6.8-18.el7 python3-libs.x86_64 0:3.6.8-18.el7

• python3-pip.noarch 0:9.0.3-8.el7 python3-setuptools.noarch 0:39.2.0-10.el7

1.3 Installed Directory​

Table 2 describes the file directories generated during the YUM installation process.

Table 2 Installation directory file description

1.4 RPM installation​

RPM installations, by the way, need to be installed in this order:

yum install -y libicu libxslt python3                   --先安装依赖
rpm -ivh ivorysql1-libs-1.2-1.rhel7.x86_64.rpm
rpm -ivh ivorysql1-1.2-1.rhel7.x86_64.rpm
rpm -ivh ivorysql1-contrib-1.2-1.rhel7.x86_64.rpm --nodeps
rpm -ivh ivorysql1-server-1.2-1.rhel7.x86_64.rpm

So, it's quite convenient to install using YUM. If not, download it separately and install it in this order.

Download address: https://yum.highgo.ca/ivorysql.html

Click BROWSE Repository-1 to find the corresponding package to download (note: dependency packages are not available on the website).

Initialize the database​

The IvorySQL database is easy to initialize and start or stop by default.

2.1 Default Initialization​

To initialize the system, run the following command as user root:

/usr/local/ivorysql/ivorysql-1/bin/ivorysql-1-setup initdb

Note: IvorysQL-1 is read by default because SERVICE_NAME is not provided.

Enable and start the service:

systemctl enable --now ivorysql-1.service

IvorysqL-1-setup

ivorysql-1-setup {initdb|check_upgrade|upgrade} [SERVICE_NAME]

Note: For details about how to use this command, run ivorysqL-1-setup --help.

2.2 Custom Initialization​

If we have a requirement to specify the data file path (/ ivorysQL /1.2/data/) and port number (5866), then we can customize the initialization.

According to the default service file "/ usr/lib/systemd/system/ivorysql - 1. The service" in the same directory replication of a new "ivorysql - 5866. The service" :

cp /usr/lib/systemd/system/ivorysql-1.service /usr/lib/systemd/system/ivorysql-5866.service

Modify Add the following information:

Environment=PGDATA=/ivorysql/1.2/data/
Environment=PGPORT=5866

Specify SERVICE_NAME as ivorysQL-5866 to initialize:

/usr/local/ivorysql/ivorysql-1/bin/ivorysql-1-setup initdb ivorysql-5866

Enable and start the service:

systemctl enable --now ivorysql-5866.service

2.3 Common Service Operations​

IvorSQL Database service operation commands:

systemctl start ivorysql-1.service              --启动数据库服务
systemctl stop ivorysql-1.service               --停止数据库服务
systemctl restart ivorysql-1.service            --重启数据库
systemctl status ivorysql-1.service         --查看数据库状态
systemctl reload ivorysql-1.service         --可以满足部分数据库配置修改完后生效

Configure database services​

We only have a simple configuration here, can be local and remote connection is ok

3.1 Client Authentication​

Modify the/var/lib/ivorysql/ivorysql - 1 / data/pg_hba. Conf, add the following content:

host    all             all             0.0.0.0/0               scram-sha-256

Run the following command to load the configuration:

systemctl reload ivorysql-1.service

3.2 Basic Parameters​

Switch to user ivorysQL:

su - ivorysql

Connect to database through PSQL:

psql

Change ivorysQL password for remote connection:

alter system set listen_addresses = '*';
alter user ivorysql password '666666';

Note: User ivorysQL does not have a password. If you do not change the password, you can change the client authentication mode to Trust to avoid secret login.

Return to user root and restart the service for the Settings to take effect:

systemctl restart ivorysql-1.service

The firewall​

If the firewall is enabled, port 5333 needs to be opened:

firewall-cmd --zone=public --add-port=5333/tcp --permanent
firewall-cmd --reload

Note: The default ivorysQL service port is 5333. If this port is disabled, external clients fail to connect to the IVorysQL service through an IP address.

The client connects to the database​

The IvorySQL client is the same as the PostgreSQL client.

4.1 PSQL connection​

Operating system user IvorysQL session connection:

[root@Node02 ~]# su - ivorysql 
Last login: Wed Apr 27 23:58:57 CST 2022 on pts/0
-bash-4.2$ psql
psql (14.2)
Type "help" for help.

ivorysql=#

4.2 DBeaver connection​

DBeaver is a powerful open source tool with the following connectivity configurations:

4.3 Highgo Developer connection​

Highgo Developer is a tool independently developed by Highgo, which supports not only Highgo database, but also PostgreSQL and IvorySQL database. The connection configuration is as follows:

Uninstall​

Since we installed through yum, it is recommended to use yum to uninstall. Try not to use RPM, which may cause incomplete uninstall. Of course, you can also uninstall it according to the Yum installation list.

5.1 Backing Up Data​

Data directory in/var/lib/ivorysql under/data/ivorysql - 1, so we can this directory will be protected, and best to stop the service, do a backup.

5.2 YUM uninstall​

Stop the database service first:

systemctl stop ivorysql-1.service

Use the "yum history list" to determine the transaction ID of the yum installation:

[root@Node02 ~]# yum history list
Loaded plugins: fastestmirror
ID     | Login user               | Date and time    | Action(s)      | Altered
-------------------------------------------------------------------------------
     5 | root <root>              | 2022-04-27 12:38 | Install        |   11  <
     4 | root <root>              | 2022-03-26 16:08 | Install        |   35 > 
     3 | root <root>              | 2022-03-26 16:07 | I, U           |   19   
     2 | root <root>              | 2022-03-26 16:07 | I, U           |   73   
     1 | System <unset>           | 2022-03-26 15:59 | Install        |  299   
history list

You can see that ID 5 is the transaction that performs the installation. Run the following command to uninstall (replace XX with 5) :

yum history undo XX

You can also use the following command to uninstall:

yum remove ivorysql-server

However, the command is not completely uninstalled, only removing two dependencies and failing to remove eight dependencies. You can decide whether to uninstall this way depending on whether to keep these dependencies.
