Spring Boot项目部署到Ubuntu

常用命令

sudo netstat -an|grep -e 3306 
sudo netstat -tap | grep mysql	#是否安装成功

一、安装MySQL

sudo apt-get install mysql-server
sudo netstat -tap | grep mysql

二、出现的问题

0、改密码

sudo cat /etc/mysql/debian.cnf
mysql -u debian-sys-maint -p
use mysql;
update user set authentication_string=password('root') where user='root' and Host ='localhost';
update user set plugin="mysql_native_password";
flush privileges;
quit;
sudo service mysql restart

mysql -u root -p // 启动后输入已经修改好的密码：root

1、mysql出现ERROR1698(28000):Access denied for user root@localhost错误解决方法

  1. 修改
sudo nano /etc/mysql/mysql.conf.d/mysqld.cnf
  1. 在[mysqld]中加入skip-grant-tables，之后重启mysql。
skip-grant-tables
/etc/init.d/mysql restart
  1. mysql -uroot -p，如果提示输入密码直接回车即可。进入mysqmysqll后执行：
use mysql;

select user,plugin from user;

# update user set authentication_string=password('root') where user='root' and Host ='localhost';

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

update user set authentication_string=password("123456"),plugin='mysql_native_password' where user='root';

flush privileges;
  1. 退出mysql，在/etc/mysql/mysql.conf.d/mysqld.cnf中删除skip-grant-tables，之后重启mysql即可进入。
  2. select user,plugin from user;
update user set authentication_string=password("123456"),plugin='mysql_native_password' where user='root';
启动
sudo service mysql start
sudo service mysql restart
sudo netstat -tap | grep mysql
登录
mysql -uroot -proot
重启mysql
/etc/init.d/mysql restart
检查mysql是不是在运行
sudo service mysql status
sudo netstat -tap | grep mysql  	查看mysql是否启动
#dsk@DSK:~$ sudo netstat -tap | grep mysql
#tcp6       0      0 [::]:mysql              [::]:*                  LISTEN      255100/mysqld
卸载：

首先在终端中查看MySQL的依赖项：

dpkg --list|grep mysql

卸载：

sudo apt-get autoremove --purge mysql-server-5.7

清除残留数据：

dpkg -l|grep ^rc|awk '{print$2}'|sudo xargs dpkg -P

再次查看MySQL的剩余依赖项：

dpkg --list|grep mysql

继续删除剩余依赖项，如：

sudo apt-get autoremove --purge mysql-apt-config
sudo apt purge mysql-*
sudo rm -rf /etc/mysql/ /var/lib/mysql
sudo apt autoremove

三、创建数据库

create database shared_device; 
use shared_device; 
source ./shared_device.sql

四、运行jar包

java -jar jar包名。
sudo fuser -v 8080/tcp			//查看8080端口进程

五、开启MySQL数据库远程访问权限

1、打开mysql配置文件

vi /etc/mysql/mysql.conf.d/mysqld.cnf
# 将bind-address = 127.0.0.1注销

2、修改数据库属性

mysql -uroot -p123456
mysql>use mysql; 
mysql>update user set host = '%' where user = 'root'; 
mysql>select host, user from user;
mysql>flush privileges;

Springboot部署到Ubuntu后MySql链接失败的问题

第6行是关键

是Mysql数据库的SSL连接问题，提示警告不建议使用没有带服务器身份验证的SSL连接，是在MYSQL5.5.45+, 5.6.26+ and 5.7.6+版本中才有的这个问题。解决办法在警告中已经说明了：

1、SpringBoot启动报错：HikariPool-1 - Exception during pool initialization.

1、mysql-connector-java

由于springboot自带 mysql-connector-java版本过高，导致连接失败，最终导致连接池启动失败。
降低mysql-connector-java的版本。

<dependency>
	<groupId>mysql</groupId>
	<artifactId>mysql-connector-java</artifactId>
	<version>5.1.40</version>
	<scope>runtime</scope>
</dependency>

**2、在数据库连接的url中添加useSSL=false;*****2.url中添加useSSL=true，并且提供服务器的验证证书。**如果只是做一个测试的话，没必要搞证书那么麻烦啦，在连接后添加一个useSSL=false即可，例如：

url: jdbc:mysql://localhost:3306/myspringbootdatabase?useSSL=false

Vue项目部署到Nginx

一、安装依赖库

#更新源
sudo apt-get update
#安装c++依赖库
sudo apt-get install build-essential
sudo apt-get install libtool
#安装openssl依赖库
sudo apt-get install openssl
#安装pcre依赖库
sudo apt-get install libpcre3 libpcre3-dev
#安装zlib依赖库
sudo apt-get install zlib1g-dev

二、编译安装Nginx

下载nginx 1.1版本

wget http://nginx.org/download/nginx-1.11.3.tar.gz

解压并进入目录

tar -zxvf nginx-1.11.3.tar.gz

cd nginx-1.11.3

配置，将nginx安装到/usr/local/ngnix目录

./configure --prefix=/usr/local/nginx

编译

make
出现错误

问题描述

在Ubuntu18.04上安装Ngnix，在编译步骤出现如下错误：

cc1: all warnings being treated as errors
objs/Makefile:460: recipe for target ‘objs/src/core/ngx_murmurhash.o’ failed
make[1]: *** [objs/src/core/ngx_murmurhash.o] Error 1
make[1]: Leaving directory ‘/home/wzj/tools/nginx/nginx-1.11.3’
Makefile:8: recipe for target ‘build’ failed
make: *** [build] Error 2
解决办法
找到对应的Maakefile文件，将gcc参数中的-Werror去掉。

我上面显示的是objs/Makefile文件，我打开看了下，将第三行的-Werror去掉就可以

mysql Ubuntu springboot驱动 ubuntu部署springboot_nginx

安装

make install

三、测试是否安装成功

1. 执行下面命令启动nginx（root用户执行）

/usr/local/nginx/sbin/nginx

2.查看是否有nginx进程启动，有进程启动，说明安装成功了

ps -ef | grep nginx

四、Nginx常用命令

1.启动服务

/usr/local/nginx/sbin/nginx

2.停止服务

/usr/local/nginx/sbin/nginx  -s stop

3.重新加载配置

/usr/local/nginx/sbin/nginx  -s reload

4.测试配置文件是否正确

/usr/local/nginx/sbin/nginx -t

五 、路径配置

Vue项目目录

#配置到根目录下（root用户下cd ..）
mkdir var/
cd var/
mkdir www/
cd www/
mkdir VueProject/
cp -r ~/dist/ .			#复制到当前目录

修改nginx配置文件

配置文件为conf下的nginx.conf,修改nginx.conf中的server配置片段

#按照以上安装设置，其路径为
/usr/local/nginx/conf
