1. Install Java and Tomcat
Use the RZ or FTP tool to upload java.gz and tomcat.gz to the /opt directory
Tar ZXVF jdK-8u191-linux-x64.tar. gz decompress the package
Vim /etc/profile Add Java environment variables as follows:
#java env
JAVA_HOME=/opt/jdk1.8.0_191
JRE_HOME=$JAVA_HOME/jre
PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin
CLASSPATH=:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib/dt.jar
export JAVA_HOME JRE_HOME PATH CLASSPATH
Copy the codeAdd it directly to the end of the file, and the effect after adding is shown as follows:
After saving the Settings, run source /etc/profile to take effect of environment variables
Run the Java -version command to check the JDK version.
Upload tomcat.gz to the opt directory
Tar ZXVF apache-tomcat-8.5.30.tar.gz Decompress the package
Chmod 777 apache-tomcat-8.5.30 Add permission
CD /opt/apache-tomcat-8.5.30/bin Go to the bin directory
Run the./startup.sh command to start tomcat. Port 8080 is used by default. You can use a browser to check whether tomcat is successfully started
JDK and Tomcat have been installed successfully
2. Installation of mysql
CD into the/opt directory wget download mysql repo source at http://repo.mysql.com/mysql57-community-release-el7-8.noarch.rpm
rpm -ivh mysql57-community-release-el7-8.noarch.rpm
Yum -y install mysql-server
Service mysqld restart Starts mysql
Run the following command to query the initial password: grep “password” /var/log/mysqld.log
Then change the password and create a remote user mysql -u root -p
Copy the initial password and paste Enter Password:
alter user ‘root’@’localhost’ identified by ‘Aa@123123’; (Aa123123 is the new password.)
CREATE USER ‘root’@’%’ IDENTIFIED BY ”Aa@123123”; Example Create a remote user
grant all on *.* to ‘root’@’%’ identified by ”’Aa@123123”’ with grant option; Assigning root permission
Flush PRIVILEGES Refresh permission
Process the screenshot
Navicat Premium is used to verify mysql installation.
3. Install SVN
CD/Go to the root directory
yum install subversion
cd /data
Mkdir SVN # Create a directory to store the SVN directory
Svnadmin create./ SVN /test/ # Create a SVN repository
View the contents of the directory:
drwxr-xr-x 2 root root 4096 Dec 1 15:10 conf
drwxr-sr-x 6 root root 4096 Dec 1 15:10 db
-r--r--r-- 1 root root 2 Dec 1 15:10 format
drwxr-xr-x 2 root root 4096 Dec 1 15:10 hooks
drwxr-xr-x 2 root root 4096 Dec 1 15:10 locks
-rw-r--r-- 1 root root 229 Dec 1 15:10 README.txt
Copy the codeThe following notes about the catalogue:
Hooks directory: the directory where the hook footsteps file is located
The LOCKS directory: the directory where Subversion’s DB lock files and db_logs lock files are stored and used to track clients accessing file libraries
The format directory: is a text file that contains only an integer representing the version number of the current file library configuration
Conf directory: this is the repository configuration file (repository user access accounts, permissions)
CD conf Modify configuration items
Vim SVNserve. conf Release the comments on the following configuration items, as shown in the figure
:wq Save vim passwd and add a user
Vim Auhz licenses the user
Svnserve -d -r /data/ SVN / # Start SVN Use the SVN client for authentication
After this page is displayed, the SVN is successfully installed. If the SVN cannot be connected, disable the firewall or set the whitelist.
4. Install Jinkins
1. Download the dependent wget -o/etc/yum repos. D/Jenkins. ‘https://pkg.jenkins.io/redhat-stable/jenkins.repo
2. Import the secret-key RPM – import https://pkg.jenkins.io/redhat-stable/jenkins.io.key
3. Install yum install Jenkins
Install Jenkins RPM -ql Jenkins
/usr/lib/jenkins/ Jenkins installation directory where the war package will be placed.
/etc/sysconfig/jenkins Jenkins configuration file, “port”, “JENKINS_HOME” can be configured here.
/var/lib/jenkins/ default JENKINS_HOME.
The/var/log/Jenkins Jenkins. Log Jenkins log file.
Jenkins port setting, default 8080
Vim /etc/sysconfig/jenkins find JENKINS_PORT and change it to 8888
Start Jenkins systemctl start Jenkins
We used systemctl status jenkins.service to check the detailed error message.
Starting Jenkins bash: /usr/bin/java: No such file or directory
Vim /etc/sysconfig/jenkins
JENKINS_JAVA_CMD=”/opt/jdk1.8.0_191/bin/ Java”
For convenience, I am lazy and set JENKINS_USER directly to root to save trouble.
Run the systemctl start Jenkins command to start Jenkins.
Let’s open it with the browser and try it out, and follow the instructions for subsequent installation
Be sure to select select plug-in to install, then unselect the plug-in and click Install.
Due to the special network environment, if you select plug-ins, some plug-ins may fail to be installed, which is troublesome and pits. Therefore, install the basic environment first, and then manually download and install plug-ins.
Then follow the prompts to complete the installation.
Subversion plug-in installation, in this order to updates.jenkins-ci.org/download/pl… Directly press Ctrl+F to search, then click enter, now the latest version is ok, and then upload in order, upload the location in System Management -> Plug-in Management -> Advanced -> Upload plug-in, as shown in the picture
Install in the following order
1.script-security.hpi
2.command-launcher.hpi

This is a screenshot of the complete installation
Maven plug-in installation, directly to the optional plug-in search Maven Integration, test can be installed.
Conf /setting. XML to change the location of the local repository and the default nexus address of the remote repository

Copy the codeSave the file and upload it to the /opt directory
At this point, the Jenkins installation is basically over
