服务器搭建

阿里云服务器
1.配置阿里云服务器实例入方向的端口：默认的端口+tomcat8080+数据库3306

2.修改服务器实例的登录密码，可以使用Xshell登录服务器

3.登录Xshell，创建jar放置文件夹：uploadFile

4.下载jar到文件夹uploadFile:apache-tomcat-7.0.94.tar.gz/jdk-8u211-linux-x64.tar.gz/mysql80-community-release-el7-2.noarch.rpm

5.进入到uploadFile文件夹下，创建jdk文件夹存放jdk解压文件，解压执行tar -zxvf jdk-8u211-linux-x64.tar.gz -C /usr/local/uploadFile/jdk

6.修改文件，执行命令：vim /etc/profile，在文件下添加信息：
export JAVA_HOME=/usr/local/uploadFile/jdk/jdk1.8.0_211
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
export PATH=${JAVA_HOME}/bin:$PATH

7.执行命令：source /etc/profile加载文件

8.修改后可查看java版本：java -version

9.创建文件夹：mkdir /usr/local/tomcat

10.解压执行tar -zxvf apache-tomcat-7.0.94.tar.gz -C /usr/local/tomcat/

11.进入文件:cd ../tomcat/apache-tomcat-7.0.94/conf/

12.修改文件：vim server.xml
保留：<Connector port="8080" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" />
删除下面的连接：<Connector port="80.." />

13.进入tomcat的bin文件夹下

14.配置防火墙，允许端口进入防火墙命令：iptables -I INPUT -p tcp --dport 8080 -j ACCEPT

15.查看防火墙状态：service firewalld status

16.启动/停止tomcat项目：./startup.sh ./shutdown.sh 验证是否启动：ip+端口号或用命令：ps -aux|grep java

17.进入到uploadFile目录下，解压执行：rpm -ivh mysql80-community-release-el7-2.noarch.rpm

18.安装mysql服务：yum install mysql-server

19.执行命令：mysqld --initialize

20.查看mysql的版本：mysqladmin --version

21.修改权限：chown mysql:mysql -R /var/lib/mysql

22.找到mysql配置文件：find / -name my.cnf
修改成：
# For advice on how to change settings please see
# http://dev.mysql.com/doc/refman/5.7/en/server-configuration-defaults.html

[mysqld]
#
# Remove leading # and set to the amount of RAM for the most important data
# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
# innodb_buffer_pool_size = 128M
#
# Remove leading # to turn on a very important data integrity option: logging
# changes to the binary log between backups.
# log_bin
#
# Remove leading # to set options mainly useful for reporting servers.
# The server defaults are faster for transactions and fast SELECTs.
# Adjust sizes as needed, experiment to find the optimal values.
# join_buffer_size = 128M
# sort_buffer_size = 2M
# read_rnd_buffer_size = 2M

character-set-client-handshake=FALSE
character-set-server=utf8mb4
collation-server=utf8mb4_general_ci
init_connect='SET NAMES utf8mb4'

datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock

# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0

log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid

23.创建mysql文件夹：mkdir -p /var/run/mysqld/

24.修改权限：chown mysql.mysql /var/run/mysqld/
//多余的步骤25
25.配置mysql存储位置：/usr/local/mysql/bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data

26.启动/停止mysql服务：service mysqld start/sudo systemctl start mysqld.service service mysqld stop

27.mysql服务开机自启：systemctl enable mysqld

28.查看mysql临时密码：grep 'temporary password' /var/log/mysqld.log

29.登录mysql:mysql -uroot -p

30.进入mysql后，允许远程登录mysql配置：
use mysql;
select host,user from user;
update user set host = '%' where user = 'root';
FLUSH PRIVILEGES
ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY '123';

31.把JAVA项目打包放在/usr/local/tomcat/apache-tomcat-7.0.94/webapps下启动tomcat即可
