Before you start, validate that you have access to the prerequisite software so you can install them in the right order. This includes a JRE, a supported database, Tomcat application server, a message broker (i.e. ActiveMQ), Alfresco Search Services, and additional components (such as ImageMagick).

Install JRE 11.0

$ sudo apt install default-jre
...
$ java --version
openjdk 11.0.4 2019-07-16

Install MySQL 8.0

# Download repository
$ curl -OL https://dev.mysql.com/get/mysql-apt-config_0.8.14-1_all.deb

# Install MySQL repository package.
$ sudo dpkg -i mysql-apt-config_0.8.14-1_all.deb
# Scroll down and select the last option - **"Ok"**
$ sudo apt update
# Install MySQL server
$ sudo apt install mysql-server

Preparing MySQL database

Create a database with the UTF-8 character set and the utf8_bin collation

mysql> CREATE DATABASE alfresco character set UTF8 collate utf8_bin;

Create a new MySQL user

mysql> CREATE USER 'alfresco'@'localhost' IDENTIFIED BY 'alfresco';

Grant the all privileges of the database

mysql> GRANT ALL PRIVILEGES ON alfresco.* TO 'alfresco'@'localhost';
mysql> FLUSH PRIVILEGES;

Increase the maximum connections ```mysql mysql> show variables like “max_connections”; +—————–+——-+ | Variable_name | Value | +—————–+——-+ | max_connections | 151 | +—————–+——-+

mysql> SET PERSIST max_connections = 275; mysql> show variables like “max_connections”; +—————–+——-+ | Variable_name | Value | +—————–+——-+ | max_connections | 275 | +—————–+——-+

The file **mysqld-auto.cnf** is created the first time a **SET PERSIST** statement is executed. Further SET PERSIST statement executions will append the contents to this file.  **RESET PERSIST** removes persisted settings from **mysqld-auto.cnf**

### [Install Tomcat 9](https://linuxize.com/post/how-to-install-tomcat-9-on-ubuntu-18-04/)
* Create Tomcat User
```shell
$ sudo useradd -r -m -U -d /opt/tomcat -s /bin/false tomcat

Install Tomcat ```shell
download the Tomcat archive

$ wget http://www-eu.apache.org/dist/tomcat/tomcat-9/v9.0.29/bin/apache-tomcat-9.0.29.tar.gz -P /tmp

extract the Tomcat archive

$ sudo tar xf /tmp/apache-tomcat-9*.tar.gz -C /opt/tomcat

create symbolic link

$ sudo ln -s /opt/tomcat/apache-tomcat-9.0.29 /opt/tomcat/latest

changes the directory ownership

$ sudo chown -RH tomcat: /opt/tomcat/latest

scripts inside bin directory must have executable flag:

$ sudo sh -c ‘chmod +x /opt/tomcat/latest/bin/*.sh’

### Create a systemd Tomcat Unit File
* create a file named `tomcat.service`
```shell
$ sudo nano /etc/systemd/system/tomcat.service

Paste the following configuration:

[Unit]
Description=Tomcat 9 servlet container
After=network.target

[Service]
Type=forking

User=tomcat
Group=tomcat

Environment="JAVA_HOME=/usr/lib/jvm/default-java"
Environment="JAVA_OPTS=-Djava.security.egd=file:///dev/urandom -Djava.awt.headless=true"

Environment="CATALINA_BASE=/opt/tomcat/latest"
Environment="CATALINA_HOME=/opt/tomcat/latest"
Environment="CATALINA_PID=/opt/tomcat/latest/temp/tomcat.pid"
Environment="CATALINA_OPTS=-Xms512M -Xmx1024M -server -XX:+UseParallelGC"

ExecStart=/opt/tomcat/latest/bin/startup.sh
ExecStop=/opt/tomcat/latest/bin/shutdown.sh

[Install]
WantedBy=multi-user.target

JVM settings

alfresco version 5.x ../tomcat/bin/setenv.sh

...
JAVA_OPTS="-Xms4G -Xmx8G $JAVA_OPTS " # java-memory-settings
...

Xmx specifies the maximum memory allocation pool for a Java virtual machine (JVM),
Xms specifies the initial memory allocation pool.
notify systemd that we created a new unit file
```
$ sudo systemctl daemon-reload
```
Start the Tomcat service
```
$ sudo systemctl start tomcat
```
Check the service status
```
$ sudo systemctl status tomcat
```
enable the Tomcat service to be automatically started at boot time
```
$ sudo systemctl enable tomcat
```

Configure Tomcat Web Management Interface

add a new user with access to the Tomcat web interface
```
$ sudo nano /opt/tomcat/latest/conf/tomcat-users.xml
```
/opt/tomcat/latest/conf/tomcat-users.xml: ```

* enable access to the web interface from anywhere
```shell
# Manager app
$ sudo nano /opt/tomcat/latest/webapps/manager/META-INF/context.xml
#Host Manager app
$ sudo nano /opt/tomcat/latest/webapps/host-manager/META-INF/context.xml

context.xml: comment or remove the lines

<Context antiResourceLocking="false" privileged="true" >
<!--
  <Valve className="org.apache.catalina.valves.RemoteAddrValve"
         allow="127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1" />
-->
</Context>

Copy the JDBC drivers for the database

Download Connector/J 8.0.18 from the MySQL download site:

Select Operating System: Platform Independent

  $ wget https://cdn.mysql.com//Downloads/Connector-J/mysql-connector-java-8.0.18.tar.gz

  # Extracting .tar.gz files
  $ tar xvzf mysql-connector-java-8.0.18.tar.gz

Copy the JAR file into the /lib directory. For example, for Tomcat, copy the JAR file into the <TOMCAT_HOME>/lib directory. ```
copy jar file to <TOMCAT_HOME>/lib

$ sudo cp mysql-connector-java-8.0.18/mysql-connector-java-8.0.18.jar /opt/tomcat/latest/lib/

change owner

$ sudo chown tomcat:tomcat /opt/tomcat/latest/lib/mysql-connector-java-8.0.18.jar

### Create an additional classpath to Tomcat
* Create the directories required for an Alfresco Community Edition installation under `<TOMCAT_HOME>`:
```shell
$ sudo mkdir /opt/tomcat/latest/shared

# Create the shared/classes directory.
$ sudo mkdir /opt/tomcat/latest/shared/classes

# Create the shared/lib directory.
$ sudo mkdir /opt/tomcat/latest/shared/lib

# # change owner
$ sudo chown -R tomcat:tomcat /opt/tomcat/latest/shared/

Open the <TOMCAT_HOME>/conf/catalina.properties file.
Change the value of the shared.loader= property to the following:

*/conf/catalina.properties:*

shared.loader=${catalina.base}/shared/classes

Installing the Alfresco WARs

Download the following file:

$ wget https://download.alfresco.com/cloudfront/release/community/201911-GA-build-368/alfresco-content-services-community-distribution-6.2.0-ga.zip

extract ``` $ sudo unzip alfresco-content-services-community-distribution-6.2.0-ga.zip -d /opt/

rename folder and change owner

$ cd /opt $ sudo mv alfresco-content-services-community-distribution-6.2.0-ga/ alfresco/ $ sudo chown -R tomcat:tomcat alfresco/

* Move the WAR files from `/web-server/webapps` to the `<TOMCAT_HOME>/webapps` directory.
```shell
$ sudo cp /opt/alfresco/web-server/webapps/*.* /opt/tomcat/latest/webapps/
$ $ sudo ls -la /opt/tomcat/latest/webapps/

Move the contents from /conf, and /lib under /web-serve to the existing directories under .

$ sudo cp /opt/alfresco/web-server/conf/Catalina/localhost/*.* /opt/tomcat/latest/conf/Catalina/localhost/
# change ownership
$ sudo chown -R tomcat:tomcat /opt/tomcat/latest

Set the global properties. Copy /web-server/shared/classes/alfresco-global.properties.sample to <TOMCAT_HOME>/shared/classes

$ sudo cp /opt/alfresco/web-server/shared/classes/alfresco-global.properties.sample /opt/tomcat/latest/shared/classes/alfresco-global.properties
$ sudo chown  tomcat:tomcat /opt/tomcat/latest/shared/classes/alfresco-global.properties
$ sudo nano /opt/tomcat/latest/shared/classes/alfresco-global.properties

Replace the sample configuration with the following:

#
# Set this property unless you have explicitly chosen to expose some repository APIs without authentication
solr.secureComms=https

#
# Custom content and index data location
#
dir.root=/opt/alfresco/alf_data
dir.keystore=${dir.root}/keystore

#
# Sample database connection properties
#
db.username=alfresco
db.password=alfresco

#
# MySQL connection
#
db.driver=org.gjt.mm.mysql.Driver
db.url=jdbc:mysql://localhost/alfresco?useUnicode=yes&characterEncoding=UTF-8

#
# URL Generation Parameters (The ${localname} token is replaced by the local server name)
#-------------
alfresco.context=alfresco
alfresco.host=${localname}
alfresco.port=8080
alfresco.protocol=http
share.context=share
