I use Alibaba cloud server, the selected student machine, and the system image CentOS 7.2 64 bit.

preparation:

1. Open ports for the project on Alibaba cloud console, including 80 (for website) and 22 (for remote connection)

2. Download the terminal artifact MobaXterm for remote connection to ECs. Download MobaXterm

3. Download the jdk of Linux version and select the suffix is tar.gz. Download JDK

4. Download Tomcat installation package. Download tomcat

5. Open MobaXterm and connect to ECs.

6. Upload the installation packages of jdk and tomcat to the / home directory.

7. Create java under usr directory, and then create the following two directories under java.

be careful! be careful! be careful! Now let's get to the point

1. Configure Java environment

(1) Run the decompression command in the command line window: tar - xzf / home / jdk-8u181-linux-x64 tar. gz -C /usr/java/jdk

(2) Configure the environment variable with the command: vi /etc/profile, then add the following content at the end of the file and save it:

#set java environment  
export JAVA_HOME=/usr/java/jdk/jdk1.8.0_172
export JRE_HOME=/usr/java/jdk/jdk1.8.0_172/jre  
export CLASSPATH=.:$JAVA_HOME/lib:$JRE_HOME/lib:$CLASSPATH  
export PATH=$JAVA_HOME/bin:$JRE_HOME/bin:$JAVA_HOME:$PATH

Save command: source /etc/profile

(3) Verify that the - Java command is successfully installed.

2. Install Tomcat

(1) Run the decompression command: tar -xzf / home / apache-tomcat-9.0.59 tar. gz -C /usr/java/tomcat

Add the following at the end of the file and save:

export JAVA_HOME=/usr/java/jdk/jdk1.8.0_172
export JRE_HOME=/usr/java/jdk/jdk1.8.0_172/jre

3. Deploy the project to tomcat server

(1) Upload the war package of the project to the webapps directory of Tomcat

(2) Find the server in the directory / usr/java/tomcat/apache-tomcat-9.0.59/conf / Open the XML file and add the following code at the end of the file:

(3) Go to / usr/java/tomcat/apache-tomcat-9.0.59/bin/ and run startup SH file

Command: CD / usr / Java / Tomcat / apache-tomcat-9.0.59/bin// startup. sh

(4) The browser inputs Alibaba cloud public IP address plus port 8080. The page is shown in the following figure, indicating success:

Add the project name after port 8080 to run this project, as shown in the figure below

4. Install yum

(1) Delete the original yum

rpm -aq|grep yum|xargs rpm -e --nodeps

(2) Download yum using wget

wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-3.4.3-168.el7.centos.noarch.rpm  
wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-metadata-parser-1.1.4-10.el7.x86_64.rpm  
wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.31-54.el7_8.noarch.rpm
wget http://mirrors.163.com/centos/7/os/x86_64/Packages/python-iniparse-0.4-9.el7.noarch.rpm 

(3) Install the package that yum depends on after downloading

rpm -ivh python-iniparse-0.4-9.el7.noarch.rpm 
rpm -ivh yum-3.4.3-168.el7.centos.noarch.rpm yum-metadata-parser-1.1.4-10.el7.x86_64.rpm yum-plugin-fastestmirror-1.1.31-54.el7_8.noarch.rpm --nodeps --force

(4) Download yum-3.4.3

wget http://yum.baseurl.org/download/3.4/yum-3.4.3.tar.gz
tar -zxvf yum-3.4.3.tar.gz

 Execution:./yummain.py update 
choice y

(5) Modify yum source

Enter the system yum Source directory: cd /etc/yum.repos.d

download yum Source: wget http://mirrors.163.com/.help/CentOS7-Base-163.repo

Modify source file name: mv CentOS7-Base-163.repo CentOS-Base.repo

function makecache Generate cache to make configuration effective: yum makecache

verification yum Source: yum repolist
 Check whether there is 163 identification. If yes, it proves that the configuration of domestic 163 image source is successful

function: yum clean all

to update YUM File: yum  update

5. Install MariaDB

(1) Quick install using yum or up2date

yum install -y mariadb-server

(2) mariadb related commands
