部署jdk8
1、下载相应的压缩包，下载网址www.oracle.com/technetwork…（本机地址：D:\Environment）
使用连接工具（xftp7）将压缩包上传到相应的目录（/usr/local），直接拖拽即可
2、解压jkd压缩包? ：tar -zxvf jdk-8u291-linux-x64.tar.gz
3、查看是否解压成功：ls或者是ll
4、删除相应的压缩包（也可直接在连接工具中直接删除）：rm -rf jdk-8u291-linux-x64.tar.gz
[root@localhost local]#tar -zxvf jdk-8u291-linux-x64.tar.gz
[root@localhost local]# ls
bin etc games include jdk1.8.0_291 jdk-8u291-linux-x64.tar.gz lib lib64 libexec sbin share src
[root@localhost local]# rm -rf jdk-8u291-linux-x64.tar.gz
[root@localhost local]# ls
bin etc games include jdk1.8.0_291 lib lib64 libexec sbin share src5、 编辑配置文件，配置环境变量：vi /etc/profile
? ? JAVA_HOME=/usr/local/jdk1.8.0_291
? ? CLASSPATH=$JAVA_HOME/lib/
? ? PATH=$PATH:$JAVA_HOME/bin
? ? export PATH JAVA_HOME CLASSPATH
[root@i-iw37bqcg local]# vi /etc/profile
# /etc/profile
#配置相应的环境变量
JAVA_HOME=/usr/local/jdk1.8.0_291 #根据自己的安装目录来来填写路径
CLASSPATH=$JAVA_HOME/lib/
PATH=$PATH:$JAVA_HOME/bin
export PATH JAVA_HOME CLASSPATH
?6、配置完环境变量一定要执行该命令使文件生效，发否则测试不成功：source /etc/profile? ?
7、测试是否部署成功 ：java -version
[root@i-iw37bqcg local]# java -version
java version "1.8.0_291"
Java(TM) SE Runtime Environment (build 1.8.0_291-b10)
Java HotSpot(TM) 64-Bit Server VM (build 25.291-b10, mixed mode)
部署maven
1、使用连接工具，将maven压缩包上传到Linux（直接拖到相应目录即可）
2、解压：tar -zxvf apache-maven-3.8.5-bin.tar.gz
[root@localhost local]# tar -zxvf apache-maven-3.8.5-bin.tar.gz
apache-maven-3.8.5/README.txt
（解压文件内容......）
apache-maven-3.8.5/lib/jansi-2.4.0.jar 3、配置maven环境变量，根据自己的安装路径配置：vim /etc/profile
[root@localhost bin]# vim /etc/profile
export M2_HOME=/usr/local/apache-maven-3.8.5
export PATH=${PATH}:${M2_HOME}/bin
4、使配置文件生效： source /etc/profile
5、测试是否成功 ：mvn -v
[root@localhost bin]# mvn -v
Apache Maven 3.8.5 (3599d3414f046de2324203b78ddcf9b5e4388aa0)
Maven home: /usr/local/apache-maven-3.8.5
?部署Tomcat
?注意：安装Tomcat之前需要在linux下部署jdk环境
查看是否安装jdk: java -version,如果显示jdk版本号，则证明已经安装，如果不显示，则证明没有安装
[root@i-lpmu0pww local]# java -version
java version "1.8.0_291"
Java(TM) SE Runtime Environment (build 1.8.0_291-b10)
Java HotSpot(TM) 64-Bit Server VM (build 25.291-b10, mixed mode)?2、Xshell工具连接Linux系统服务器
?将下载好的apache-tomcat-8.5.78.tar.gz 使用xftp7移动到/usr/local 目录下
?3、在xhell中执行 tar -xvzf apache-tomcat-8.5.78.tar.gz
[root@i-lpmu0pww local]# tar -xvzf apache-tomcat-8.5.78.tar.gz
apache-tomcat-8.5.78/conf/
apache-tomcat-8.5.78/conf/catalina.policy
apache-tomcat-8.5.78/conf/catalina.properties
apache-tomcat-8.5.78/conf/context.xml?
部署Mysql(tar.gz)版
检查是否已经安装，执行命令
rpm -qa | grep mysql
如果已经存在，则执行删除命令
rpm -e --nodeps 名字
查找是否有mysql相关的进程，执行命令
ps -ef|grep mysql | grep -v grep ps -ef|grep mysqld | grep -v grep
如果有，则执行下面的命令将其杀死
kill -9 进程号
查找mysql相关的文件，执行命令
find / -name mysql
如果有，将其删除或者重命名
1、将压缩包用远程连接工具上传到linux上，我上传到/opt/目录下
[root@i-f6rcqrxv opt]# ll total 629816 drwxr-xr-x 9 root root ? ? ? 129 May 11 08:55 mysql-5.7.24-linux-glibc2.12-x86_64 -rw-r--r-- 1 root root 644930593 May 10 18:04 mysql-5.7.26-linux-glibc2.12-x86_64.tar.gz
2、修改文件名称：mv
[root@i-f6rcqrxv opt]# mv mysql-5.7.24-linux-glibc2.12-x86_64/ mysql-5.7.2
3、创建mysql用户组和mysql用户
[root@i-f6rcqrxv opt]# cat /etc/group | grep mysql mysql:x:1000: [root@i-f6rcqrxv opt]# cat /etc/passwd | grep mysql mysql:x:997:1000::/home/mysql:/bin/bash
4、创建data，数据存放目录
[root@i-f6rcqrxv opt]# cd mysql-5.7.2 [root@i-f6rcqrxv mysql-5.7.2]# mkdir data
5、修改权限
[root@i-f6rcqrxv mysql-5.7.2]# chown -R mysql.mysql /opt/mysql-5.7.2
6、创建配置文件
在/opt/mysql-5.7.17/support-files目录下创建my_default.cnf，创建命令
[root@i-f6rcqrxv mysql-5.7.2]# cd /opt/mysql-5.7.2/support-files/ [root@i-f6rcqrxv support-files]# touch my_default.cnf
7、在my_default.cnf文件中复制以下内容
进入文件：[root@i-f6rcqrxv support-files]# vi my_default.cnf
[mysqld] sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES basedir = /opt/mysql-5.7.2 datadir = /opt/mysql-5.7.2/data port = 3306 socket = /tmp/mysql.sock character-set-server=utf8 log-error = /opt/mysql-5.7.2/data/mysqld.log pid-file = /opt/mysql-5.7.2/data/mysqld.pid
linux下shift+insert是粘贴，Ctrl+insert是复制
8、拷贝，如果提示是否覆盖，y
[root@i-f6rcqrxv support-files]# cp /opt/mysql-5.7.2/support-files/my_default.cnf /etc/my.cnf cp: overwrite ‘/etc/my.cnf’? y
可能会遇到的问题：my_default.cnf’: No such file or directory
原因：要使用绝对路径才可以
绝对路径：路径的写法一定是由根目录 / 写起的，例如 /usr/local/mysql
9、初始化
[root@i-f6rcqrxv support-files]# cd /opt/mysql-5.7.2 [root@i-f6rcqrxv mysql-5.7.2]# ./bin/mysqld --initialize --user=mysql --basedir=/opt/mysql-5.7.2/ --datadir=/opt/mysql-5.7.2/data/
10、初始密码
初始化之后到日志中去查看初始密码，等会登录用，可以用cat 命令查看
cat /opt/mysql-5.7.2/data/mysqld.log
[root@i-f6rcqrxv mysql-5.7.2]# cat /opt/mysql-5.7.2/data/mysqld.log 2022-05-11T02:45:41.887827Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details). 2022-05-11T02:45:41.887886Z 0 [Warning] 'NO_ZERO_DATE', 'NO_ZERO_IN_DATE' and 'ERROR_FOR_DIVISION_BY_ZERO' sql modes should be used with strict mode.

Generating a new UUID: 736ede3b-d0d4-11ec-9db3-5254a997db6d. 2022-05-11T02:45:42.994572Z 0 [Warning] Gtid table is not ready to be used. Table 'mysql.gtid_executed' cannot be opened. 2022-05-11T02:45:42.995065Z 1 [Note] A temporary password is generated for root@localhost: K+%>iHykZ2Q! #初始的用户名和密码
K+%>iHykZ2Q! 是数据库密码，一会登录时使用
11、启动
把启动脚本放到开机初始化目录
[root@i-f6rcqrxv mysql-5.7.2]# cp support-files/mysql.server /etc/init.d/mysql
启动命令
[root@i-f6rcqrxv mysql-5.7.2]# service mysql start Starting MySQL. SUCCESS!
12、登录，刚刚日志中的密码
[root@i-f6rcqrxv mysql-5.7.2]# ./bin/mysql -u root -p Enter password: #密码不会显示出来 Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 2 Server version: 5.7.24 Copyright (c) 2000, 2018, Oracle and/or its affiliates. All rights reserved. Oracle is a registered trademark of Oracle Corporation and/or its affiliates. Other names may be trademarks of their respective owners. Type 'help;' or '\h' for help. Type '\c' to clear the current input statement. mysql>
每次都要这样来登录，有点麻烦，可以这样做
ln -s /opt/mysql-5.7.2/bin/mysql /usr/bin
以后登录就可以直接用mysql命令登录了
mysql -uroot -p
mysql>
mysql> ln -s /opt/mysql-5.7.2/bin/mysql /usr/bin
-> mysql -uroot -p
->
->
13、修改密码
set password=password('1234');
flush privileges;
mysql> set password=password('1234');
Query OK, 0 rows affected, 1 warning (0.00 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
14、设置远程连接
grant all privileges on *.* to root@'%' identified by 'root'; flush privileges;
mysql> grant all privileges on *.* to root@'%' identified by 'root'; Query OK, 0 rows affected, 1 warning (0.00 sec) mysql> flush privileges; Query OK, 0 rows affected (0.00 sec)
15、重启mysql才能生效。
service mysql stop service mysql start service mysql restart
mysql> service mysql stop
-> service mysql start
-> service mysql restart
->
16、查看数据库
mysql> show databases; +--------------------+ | Database | +--------------------+ | information_schema | | mysql | | performance_schema | | sys | +--------------------+ 4 rows in set (0.00 sec)
注意事项
1、本地访问Linux数据库失败，解决方法
查看服务器的防火墙mysql端口3306是否开放
查看防火墙是否已开放3306端口 firewall-cmd --query-port=3306/tcp 设置3306端口为永久开放 firewall-cmd --add-port=3306/tcp --permanent 查看firewalld状态，发现当前是dead状态，即防火墙未开启 systemctl status firewalld 关闭防火墙 systemctl stop firewalld 重启防火墙（设置了新的端口记得先关闭，再重启） systemctl status firewalld
