Installing Archiver Appliance under CentOS7

Posted by vishal99 on Tue, 28 Dec 2021 18:06:34 +0100

1, Software installation

1.1 MySQL installation

  1. Download the installation package mysql-8.0 23-1. el7. x86_ 64.rpm-bundle. tar. gz.
  2. After decompression, the installation process shall be carried out in the following order:
    (1) mysql-community-common
    [dongxw@localhost mysql]$ sudo rpm -ivh mysql-community-common-8.0.23-1.el7.x86_64.rpm
    (2) MySQL community LIBS (remove MariaDB LIBS and install MySQL community client plugins first)
    [dongxw@localhost mysql]$ sudo rpm -ivh mysql-community-client-plugins-8.0.23-1.el7.x86_64.rpm 
[dongxw@localhost mysql]$ sudo rpm -ivh mysql-community-libs-8.0.23-1.el7.x86_64.rpm
    (3) MySQL community client (remove mariadb and mariadb server first)
    [dongxw@localhost mysql]$ sudo rpm -ivh mysql-community-client-8.0.23-1.el7.x86_64.rpm
    (4) mysql-community-server
    [dongxw@localhost mysql]$ sudo rpm -ivh mysql-community-server-8.0.23-1.el7.x86_64.rpm
  3. Some initialization settings are required after MySQL installation:
    (1) Start MySQL service:
    [dongxw@localhost ~]$ sudo mysqld --initialize
[dongxw@localhost ~]$ sudo chown mysql:mysql /var/lib/mysql -R		# Change the users and groups of / var/lib/mysql and its subdirectories
[dongxw@localhost ~]$ systemctl start mysqld.service		# Start MySQL service
[dongxw@localhost ~]$ systemctl enable mysqld
    (2) Change MySQL root password:
    [dongxw@localhost ~]$ sudo cat /var/log/mysqld.log |grep password		# View the password of the database root user
2021-08-23T06:58:17.451923Z 6 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: tQ:twskNh3UD
[dongxw@localhost ~]$ mysql -uroot -p
Enter password: tQ:twskNh3UD
mysql> alter user 'root'@'localhost' identified with mysql_native_password by '123456';
    After that, log in to MySQL on the machine again, and you can use the following commands:
    [dongxw@localhost ~]$ mysql -uroot -p123456
    (3) To create a new archappl user and database:
    Create a new MySQL user archappl for Archiver Appliance with the password archappl:
    mysql> create user 'archappl'@'%' identified by 'archappl';       # Create user first
mysql> grant all on archappl.* to 'archappl'@'%';		# Then give about archappl* All permissions of database
mysql> create database archappl; 		# Create archappl database

1.2 MySQL connector Java installation

In fact, MySQL connector Java does not need to be installed. It only needs to provide MySQL connector-java-5 when Archiver Appliance is installed- bin. Jar file. So we can download the installation package and unzip it.
(1) Get MySQL version:
bash [dongxw@localhost ~]$ mysql --version mysql Ver 8.0.23 for Linux on x86_64 (MySQL Community Server - GPL)
(2) Download installation package( https://downloads.mysql.com/archives/c-j/ )Post decompression:

You must download the Platform Independent version, because only the installation package of this version has mysql-connector-java-5- bin. Jar file for installing Archiver Appliance.

1.3 JDK installation

(1) Download binary installation package
http://www.oracle.com/technetwork/java/javase/downloads/index.html
(2) After decompression, place it in / home/dongxw/jdk-16.0.2 and define the environment variable where the executable file is located:

[dongxw@localhost ~]$ vim ~/.bashrc
...
JAVA_HOME=$HOME/jdk-16.0.2
PATH=$JAVA_HOME/bin:$HOME/modules/cs-studio:$PATH:$HOME/.local/bin
export PATH
[dongxw@localhost ~]$ . ~/.bashrc

1.4 Apache Tomcat installation

Download the installation package, unzip it and place it in / home / dongxw / Apache Tomcat / apache-tomcat-9.0 fifty-two
http://tomcat.apache.org/

1.5 Archiver Appliance installation

  1. Stand alone installation
    (1) Use the installation script to prepare for installation
    Using install_ scripts/single_ machine_ install. Before installing the SH script, the necessary installation and configuration steps include:
    1) MySQL installs and creates new archappl users and grants permissions to create archappl databases
    2) JDK installation
    3) mysql-connector-java-8.0. 23.tar. Download and unzip the GZ installation package (including mysql-connector-java-5.-bin.jar file)
    4) apache-tomcat-9.0. 52.tar. Download of GZ installation package
    5) Environment variable JAVA_HOME settings
    (this step is not necessary if you use the single_machine_install.sh script to install.)
    6) Archiver Appliance run directory creation
    (for example, create it as $HOME/modules/Tomcat_instances)

    (2) Download the installation package:
    https://github.com/slacmshankar/epicsarchiverap/releases/download/v0.0.1_SNAPSHOT_13-Nov-2019/archappl_v0.0.1_SNAPSHOT_13-November-2019T15-45-42.tar.gz
    The internal files of the installation package are as follows. If the wrong package is installed, these files are not in the package:

    [dongxw@localhost ArchiverAppliance]$ ll

    (3) Use the installation script to install
    After the above preparations are completed, run install_scripts/single_machine_install.sh script.
    1) First select the Archiver Appliance run Directory:

    2) Select apache-tomcat-9.0 52.tar. GZ installation package:

    3) Select mysql-connector-java-5- bin. Jar file:

    4) Confirm that archappl is generated by the script_ Applications environment variable:

    5) Determine the login user and database of MySQL database:

    6) You do not need to specify policies Py file:

    7) Installation succeeded:

    [dongxw@localhost Tomcat_instances]$ ll

  2. Cluster installation

2, Possible problems during installation

  1. During the script running, some Python scripts or commands will be called. Since Python is involved in the installation package, the system environment variables are used to automatically search the Python interpreter defined in the current PATH, which may call the python 3 interpreter; The corresponding Python statements (especially print statements) are written in the form of python2, so syntax errors may be triggered. There are two solutions to this problem:
    1) Modify the Python interpreter defined in PATH and put the PATH of python2 at the front. For example:
    export PATH=/usr/bin/: $ PATH
ls /usr/bin/python /usr/bin/python2.7
    2) Specify the Python interpreter everywhere in the installation package as python2. For example:
    single_machine_install.sh,  line 333:    WARSRC_DIR=`/usr/bin/python2.7 -c ...
deployMultipleTomcats.py,  line 1:    #!/usr/bin/python2.7
addMysqlConnPool.py,  line 1:    #!/usr/bin/python2.7
