ubuntu部署javaweb开发环境

ubuntu安装OracleJdk

配置jdk

进入/usr/local/bin目录cd /usr/local/bin，创建一个java目录，mkdir java，进入java目录，cd java，下载jdk

这里使用华为云的镜像站，速度较快

wget https://repo.huaweicloud.com/java/jdk/8u202-b08/jdk-8u202-linux-x64.tar.gz

解压压缩包

tar -xvzf jdk-8u202-linux-x64.tar.gz

删除压缩包

rm  -rf jdk-8u202-linux-x64.tar.gz

设置环境变量

没有vim的安装一下就可以sudo apt install vim进行安装

打开profile这个文件后，按字母i是插入，按i后左下角会显示insert，插入完成后，按esc，insert会消失，再输入:wq完成

注：如果不懂vim的操作的话，直接用管理员权限在终端中输入这几个重定向

echo 'export JAVA_HOME=/usr/local/bin/java/jdk1.8.0_202' >> /etc/profile
echo 'export JRE_HOME=${JAVA_HOME}/jre'   >> /etc/profile
echo 'export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib' >> /etc/profile
echo 'export PATH=$PATH:${JAVA_HOME}/bin' >> /etc/profile

vim操作：

vim /etc/profile

在文件末尾追加以下内容：

export JAVA_HOME=/usr/local/bin/java/jdk1.8.0_202               export JRE_HOME=${JAVA_HOME}/jre                               export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib             export PATH=$PATH:${JAVA_HOME}/bin 

更新配置信息

source /etc/profile

测试jdk是否安装成功

java -version

java version "1.8.0_202"                                                    
Java(TM) SE Runtime Environment (build 1.8.0_202-b08)                       
Java HotSpot(TM) 64-Bit Server VM (build 25.202-b08, mixed mode) 

到此，Ubuntu安装OracleJdk就成功了。

配置mysql

下载mysql：

sudo apt update
sudo apt install mysql-server

配置mysql：

sudo mysql_secure_installation

#1
VALIDATE PASSWORD PLUGIN can be used to test passwords...
Press y|Y for Yes, any other key for No: N (我的选项)

#2
Please set the password for root here...
New password: (输入密码)
Re-enter new password: (重复输入)

#3
By default, a MySQL installation has an anonymous user,
allowing anyone to log into MySQL without having to have
a user account created for them...
Remove anonymous users? (Press y|Y for Yes, any other key for No) : N (我的选项)

#4
Normally, root should only be allowed to connect from
'localhost'. This ensures that someone cannot guess at
the root password from the network...
Disallow root login remotely? (Press y|Y for Yes, any other key for No) : N (我的选项)

#5
By default, MySQL comes with a database named 'test' that
anyone can access...
Remove test database and access to it? (Press y|Y for Yes, any other key for No) : Y (我的选项)

#6
Reloading the privilege tables will ensure that all changes
made so far will take effect immediately.
Reload privilege tables now? (Press y|Y for Yes, any other key for No) : Y (我的选项)

查看mysql状态：

systemctl status mysql.service

如果显示active(running)则正常

配置远程访问：

sudo vim /etc/mysql/mysql.conf.d/mysqld.cnf 

编辑这个文件，将其中的bind-address = 127.0.0.1这句话前面加个#，注释掉

刷新权限，进入mysql后：

grant all on *.* to root@'%' identified by '你的密码' with grant option;
flush privileges;

重启mysql

systemctl restart mysql.service

配置tomcat

下载tomcat

这里我用的是9.x版本的tomcat，进 /usr/local/bin目录：

wget https://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-9/v9.0.36/bin/apache-tomcat-9.0.36.tar.gz

将下载好的tomcat压缩包解压：

tar -xvzf apache-tomcat-9.0.36.tar.gz

重命名tomcat

mv apache-tomcat-9.0.36.tar.gz tomcat

启动 tomcat

./usr/local/bin/tomcat/bin/startup.sh

tomcat配置就搞定了
