1.jdk不說了,網上一大堆
2.mysql安裝稍微說一下
wget -i -c http://dev.mysql.com/get/mysql57-community-release-el7-10.noarch.rpm
yum -y install mysql57-community-release-el7-10.noarch.rpm
yum -y install mysql-community-server
systemctl start mysqld.service
systemctl status mysqld.service
看到正在running即可
grep "password" /var/log/mysqld.log
可以看到密碼
ALTER USER 'root'@'localhost' IDENTIFIED BY 'new password';
yum -y remove mysql57-community-release-el7-10.noarch
這個把它卸載掉
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123456';
flush privileges;
如果還是無法連接,檢查是否防火牆屏蔽了mysql端口的遠程訪問權限。但是,我部署雲服務器不打算這麼做
不想把mysql允許遠程訪問,防火牆不想關。
注意mysql建庫:
CREATE DATABASE IF NOT EXISTS yourdbname DEFAULT CHARSET utf8 COLLATE utf8_general_ci;
3.打包
idea 設置
進入project Structure( 快捷鍵 Ctrl+Shift+Alt+S或者File->Project Structure ),選中‘Artifacts’,點擊中間的綠色+號(Project Settings->Artifacts->JAR->From modules with dependencies )
4.centos
yum install lrzsz
上傳jar直接啓動 java -jar XXX.jar
報錯信息
no main manifest attribute, in x.jar
使用命令
java -cp official.jar com.zhongjian.official.OfficialApplication
也會報錯

參數不對,說明這樣恐怕不行的。
java.lang.IllegalArgumentException: No auto configuration classes found in META-INF/spring.factories. If you are using a custom packaging, make sure that file is correct.
改一下maven幫我打包呢,但是:
Plugin 'org.springframework.boot:spring-boot-maven-plugin:' not found
然後就看下這個了
1,如果你的POM是繼承spring-boot-starter-parent的話,只需要下面的指定就行。
<properties>
<!-- The main class to start by executing java -jar -->
<start-class>com.mycorp.starter.HelloWorldApplication</start-class>
</properties>
2,如果你的POM不是繼承spring-boot-starter-parent的話,需要下面的指定。
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<version>1.3.5.RELEASE</version>
<configuration>
<mainClass>${start-class}</mainClass>
<layout>ZIP</layout>
</configuration>
<executions>
<execution>
<goals>
<goal>repackage</goal>
</goals>
</execution>
</executions>
</plugin>
好了,這裏pom不報錯了
但是打包依舊報錯:
Failed to execute goal org.apache.maven.plugins:maven-surefire-plugin:2.22.1:test (default-test) on project official: There are test failures.
Please refer to E:\project\official\target\surefire-reports for the individual test results.
Please refer to dump files (if any exist) [date].dump, [date]-jvmRun[N].dump and [date].dumpstream.
pom跳過即可
<!--添加配置跳過測試-->
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.22.1</version>
<configuration>
<skipTests>true</skipTests>
</configuration>
</plugin>
但是來了新的問題了,我的項目,打包不打我要執行的類了。
如果spring-boot-maven-plugin報錯,是需要添加版本號的情況的。
可以了,已經啓動了
最後一步,記得nohup一下。
nohup java -jar official-0.0.1-SNAPSHOT.jar >/dev/null 2>&1 &
