腾讯云centos7搭建javaweb服务器(本人亲自经历,详细)

时间:2022-01-25 13:02:45

首先声明,这是本人亲自搭建成功的经历,亲测有效,****(此处和谐)网上好多在云服务器上搭建javaweb的教程,好多都是各种抄的或者若干年之前的,真的是被坑惨了!废话不多说,下面直接上干货!步骤很详细,不出意外的话,应该能完美搭建成功!我真的痛恨假教程!!!

首先,为了保险起见,直接在腾讯云官网上登录云服务器管理网页,重装系统(如有什么需要保存的重要文件请提前备份)在此,本人重装的是最新的centos7.3,如图腾讯云centos7搭建javaweb服务器(本人亲自经历,详细)

若干秒之后,重装完毕,即可开始搭建环境!

去官网下载jdk和tomcat的压缩包,本着团结友爱奉献的精神……咳咳,在此贴上下载页面的链接,毕竟下载链接很快就会过时

jdk:http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

我下载的是tar包,Linux x64   jdk-8u131-linux-x64.tar.gz

Tomcat:  http://tomcat.apache.org/download-90.cgi

我下载的是apache-tomcat-8.5.16.tar.gz

恩,下载好之后,

用户可以使用putty,mac用户可以使用ssh连接到服务器

使用root用户输入密码之后即可登录服务器

依次执行:

[root@VM_77_172_centos usr]# cd /usr

[root@VM_77_172_centos usr]# mkdir java

本人使用的是filezilla软件分别将下载好的jdk和Tomcat包上传到服务器中的/usr/java目录下和/usr目录下。(注意)

先安装java:

[root@VM_77_172_centos usr]# cd java

[root@VM_77_172_centos java]# tar -xvzf jdk-8u131-linux-x64.tar.gz

[root@VM_77_172_centos java]# ls
jdk1.8.0_131  jdk-8u131-linux-x64.tar.gz

[root@VM_77_172_centos java]# vim /etc/profile

单击i可进行插入,在文末插入如下三行语句:

export JAVA_HOME=/usr/java/jdk1.8.0_131
export JRE_HOME=/$JAVA_HOME/jre
export CLASSPATH=.:$JAVA_HOME/jre/lib/rt.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin

单击esc之后输入:x保存并退出

[root@VM_77_172_centos java]# source /etc/profile

此时,java安装完毕,可输入java -version查看:

[root@VM_77_172_centos java]# java -version
java version "1.8.0_131"
Java(TM) SE Runtime Environment (build 1.8.0_131-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.131-b11, mixed mode)

下面开始Tomcat安装:

[root@VM_77_172_centos java]# cd ..

(注意,之前已经将tomcat包上传到/usr目录下)
[root@VM_77_172_centos usr]# tar -xvzf apache-tomcat-8.5.16.tar.gz

[root@VM_77_172_centos usr]# rm -r apache-tomcat-8.5.16.tar.gz

rm: remove regular file ’apache-tomcat-8.5.16.tar.gz'? y

[root@VM_77_172_centos usr]#mv apache-tomcat-8.5.16 tomcat

[root@VM_77_172_centos usr]# ls
bin  games    java  lib64    local  share  tmp
etc  include  lib   libexec  sbin   src    tomcat

[root@VM_77_172_centos tomcat]# /usr/tomcat/bin/startup.sh
Using CATALINA_BASE:   /usr/tomcat
Using CATALINA_HOME:   /usr/tomcat
Using CATALINA_TMPDIR: /usr/tomcat/temp
Using JRE_HOME:        //usr/java/jdk1.8.0_131/jre
Using CLASSPATH:       /usr/tomcat/bin/bootstrap.jar:/usr/tomcat/bin/tomcat-juli.jar
Tomcat started.

此时,tomcat安装完毕,接下来打开端口:

[root@VM_77_172_centos tomcat]# systemctl stop firewalld.service

[root@VM_77_172_centos tomcat]# systemctl disable firewalld.service
[root@VM_77_172_centos tomcat]# systemctl mask firewalld.service

Created symlink from /etc/systemd/system/firewalld.service to /dev/null.
[root@VM_77_172_centos tomcat]# cd ~
[root@VM_77_172_centos ~]# yum install iptables-services -y

[root@VM_77_172_centos ~]# systemctl enable iptables
Created symlink from /etc/systemd/system/basic.target.wants/iptables.service to /usr/lib/systemd/system/iptables.service.
[root@VM_77_172_centos ~]# systemctl start iptables

[root@VM_77_172_centos ~]# systemctl status iptables

[root@VM_77_172_centos usr]# systemctl unmask firewalld
Removed symlink /etc/systemd/system/firewalld.service.
[root@VM_77_172_centos usr]# systemctl start firewalld
[root@VM_77_172_centos usr]# firewall-cmd --zone=public --add-port=8080/tcp --permanent
success
[root@VM_77_172_centos usr]# firewall-cmd --zone=public --add-port=80/tcp --permanent
success
[root@VM_77_172_centos usr]# firewall-cmd --zone=public --add-port=22/tcp --permanent
success
[root@VM_77_172_centos usr]# firewall-cmd --zone=public --add-port=3306/tcp --permanent
success
[root@VM_77_172_centos usr]# firewall-cmd --reload
success

至此,不出意外的话,就可以外网访问服务器ip:8080看到Tomcat初始界面了!

接下来,安装mysql:

[root@VM_77_172_centos usr]# cd ~
[root@VM_77_172_centos ~]# wget http://repo.mysql.com//mysql57-community-release-el7-7.noarch.rpm

[root@VM_77_172_centos ~]# rpm -ivh mysql57-community-release-el7-7.noarch.rpm

[root@VM_77_172_centos ~]# yum install mysql-server

中间输入若干次y

[root@VM_77_172_centos ~]# yum install mysql-devel

中间输入若干次y

[root@VM_77_172_centos ~]# yum install mysql

检查一下MySQL:

[root@VM_77_172_centos ~]# rpm -qa|grep -i mysql
mysql-community-libs-5.7.18-1.el7.x86_64
mysql-community-libs-compat-5.7.18-1.el7.x86_64
mysql57-community-release-el7-7.noarch
mysql-community-common-5.7.18-1.el7.x86_64
mysql-community-client-5.7.18-1.el7.x86_64
mysql-community-server-5.7.18-1.el7.x86_64
mysql-community-devel-5.7.18-1.el7.x86_64

[root@VM_77_172_centos ~]# service mysqld start
Redirecting to /bin/systemctl start  mysqld.service

[root@VM_77_172_centos ~]# vim /etc/my.cnf

添加一条语句:skip-grant-tables

保存退出
[root@VM_77_172_centos ~]# service mysqld restart
Redirecting to /bin/systemctl restart  mysqld.service
[root@VM_77_172_centos ~]# mysql -u root

即可进入mysql

mysql> use mysql;
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A


Database changed
mysql> update mysql.user set authentication_string=password('123456') where user='root';
Query OK, 1 row affected, 1 warning (0.00 sec)
Rows matched: 1  Changed: 1  Warnings: 1


mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)


mysql> exit;
Bye
[root@VM_77_172_centos ~]# vim /etc/my.cnf

删除掉刚才添加的那条语句,保存退出。

[root@VM_77_172_centos ~]# service mysqld restart
Redirecting to /bin/systemctl restart  mysqld.service
[root@VM_77_172_centos ~]# mysql -uroot -p

输入密码登录MySQL

mysql> set global validate_password_policy=0;

Query OK, 0 rows affected (0.00 sec)


mysql> set global validate_password_length=6;
Query OK, 0 rows affected (0.00 sec)


mysql> set PASSWORD = PASSWORD('123456');
Query OK, 0 rows affected, 1 warning (0.00 sec)


mysql> ALTER USER 'root'@'localhost' PASSWORD EXPIRE NEVER;
Query OK, 0 rows affected (0.01 sec)


mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)


mysql> use mysql;
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A


Database changed
mysql> update user set host='%' where user='root' and host='localhost';
Query OK, 1 row affected (0.00 sec)
Rows matched: 1  Changed: 1  Warnings: 0


mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)


mysql> quit
Bye

至此,MySQL也安装完毕!

享受没有配置错误的流程吧!
