How to set up a deployment project under Linux system

1. Modify the firewall settings and open the corresponding ports

To modify the Linux system firewall configuration, you need to modify the /etc/sysconfig/iptables file. If you want to open a port, add a line in it.

-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 8080 -j ACCEPT, where 8080 is the port number to be opened, and then restart the Linux firewall service

2. Install JDK

1. Check the jdk version in the system

[root@localhost software]# java -version

2. Detect the jdk installation package

[root@localhost software]# rpm -qa | grep java

show:

.0-openjdk-1.7.0.111-2.6.7.8.el7.x86_64 python-javapackages-3.4.1-11.el7.noarch tzdata-java-2016g-2.el7.noarch javapackages-tools-3.4.1-11.el7.noarch java-1.8.0-openjdk-1.8.0.102-4.b14.el7.x86_64 java-1.8.0-openjdk-headless-1.8.0.102-4.b14.el7.x86_64 java-1.7.0-openjdk-headless-1.7.0.111-2.6.7.8.el7.x86_64

3. Uninstall openjdk

[root@localhost software]# rpm -e --nodeps tzdata-java-2016g-2.el7.noarch
[root@localhost software]# rpm -e --nodeps java-1.7.0-openjdk-1.7.0.111-2.6.7.8.el7.x86_64
[root@localhost software]# rpm -e --nodeps java-1.7.0-openjdk-headless-1.7.0.111-2.6.7.8.el7.x86_64
[root@localhost software]# rpm -e --nodeps java-1.8.0-openjdk-1.8.0.102-4.b14.el7.x86_64
[root@localhost software]# rpm -e --nodeps java-1.8.0-openjdk-headless-1.8.0.102-4.b14.el7.x86_64

Or use

[root@localhost jvm]# yum remove *openjdk*

Then enter rpm -qa | grep java again to view the uninstall status:

[root@localhost software]# rpm -qa | grep java python-javapackages-3.4.1-11.el7.noarch javapackages-tools-3.4.1-11.el7.noarch

4. Install a new JDK

First, go to the JDK official website to download the JDK version you want. After the download is complete, put the JDK installation package to be installed in the folder specified by the Linux system, and enter the folder with the command

Unzip the jdk-8u131-linux-x64.tar.gz installation package

[root@localhost software]# mkdir -p /usr/lib/jvm
[root@localhost software]# tar -zxvf jdk-8u131-linux-x64.tar.gz -C /usr/lib/jvm

5. Set environment variables

[root@localhost software]# vim /etc/profile

Add at the very beginning:

export JAVA_HOME=/usr/lib/jvm/jdk1.8.0_131 
export JRE_HOME=${JAVA_HOME}/jre 
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib 
export PATH=${JAVA_HOME}/bin:$PATH

6. Execute the profile file

[root@localhost software]# source /etc/profile

This allows the configuration to take effect immediately without restarting.

7. Check the newly installed JDK

3. Install tomcat

4. Install MySQL

1. If it has been installed before, uninstall it first

2. Enter the yum list | grep mysql command to view the downloadable version of the MySQL database provided by yum

3.yum install -y mysql-server mysql mysql-devel

Yum will help us select the software needed to install the MySQL database and some other attached software

4. Start mysql, service mysqld start

Log in to mysql and set the password as follows:

mysql> use mysql;
mysql> update user set password=password('123') where user='root' and host='localhost';
mysql> flush privileges;

5. Set mysql to allow remote connection

GRANT ALL PRIVILEGES ON *.* TO root@'%' IDENTIFIED BY 'password' WITH GRANT OPTION;

6. Open ports

7. Start the mysql service, mysql -u username -p password

5. Package the project into tomcat, configure other required environments, and start tomcat
