一、实验拓扑

Ctenos7安装mysql-8.1.0/tomcat-9.0.80/LNMT部署,mysql,数据库

二、部署mysql

官网下载地址https://dev.mysql.com/downloads/mysql/

1、移除mariadb，安装所需应用

                                    mysql-8.1.0 社区版 安装说明

官网下载地址https://dev.mysql.com/downloads/mysql/

1、yum remove mariadb
2、yum -y install liaio net-tools
3、解压安装包，进入安装包执行以下命令
yum install -y perl-Module-Install.noarch
yum install perl-Test-*.noarch -y
rpm -ivh mysql-community-common-8.1.0-1.el7.x86_64.rpm 
rpm -ivh mysql-community-client-plugins-8.1.0-1.el7.x86_64.rpm 
rpm -ivh mysql-community-libs-8.1.0-1.el7.x86_64.rpm 
yum install -y perl-Module-Install.noarch
rpm -ivh mysql-community-common-8.1.0-1.el7.x86_64.rpm 
rpm -ivh mysql-community-client-plugins-8.1.0-1.el7.x86_64.rpm 
rpm -ivh mysql-community-libs-8.1.0-1.el7.x86_64.rpm 
yum install perl-Test-*.noarch -y
rpm -ivh mysql-community-libs-8.1.0-1.el7.x86_64.rpm 
yum remove mariadb-libs.x86_64 -y
rpm -ivh mysql-community-libs-8.1.0-1.el7.x86_64.rpm 
rpm -ivh mysql-community-libs-compat-8.1.0-1.el7.x86_64.rpm 
rpm -ivh mysql-community-client-8.1.0-1.el7.x86_64.rpm 
rpm -ivh mysql-community-debuginfo-8.1.0-1.el7.x86_64.rpm 
rpm -ivh mysql-community-embedded-compat-8.1.0-1.el7.x86_64.rpm 
rpm -ivh mysql-community-icu-data-files-8.1.0-1.el7.x86_64.rpm 
rpm -ivh mysql-community-server-8.1.0-1.el7.x86_64.rpm 
 rpm -ivh mysql-community-server-debug-8.1.0-1.el7.x86_64.rpm 
rpm -ivh mysql-community-devel-8.1.0-1.el7.x86_64.rpm 
yum install -y openssl
rpm -ivh mysql-community-devel-8.1.0-1.el7.x86_64.rpm 
yum install -y openssl*
rpm -ivh mysql-community-devel-8.1.0-1.el7.x86_64.rpm 
rpm -ivh mysql-community-test-8.1.0-1.el7.x86_64.rpm 
yum install -y perl*
rpm -ivh mysql-community-test-8.1.0-1.el7.x86_64.rpm 
4、启动MYSQL
systemctl start mysqld
5、查看临时密码
cat /var/log/mysqld.log | grep password
6、登录MYSQL
mysql -u root -p
7、修改密码
alter user 'root'@'localhost' identified by '123456.Com';
flush privileges
创建库jx
create database jx;
8、远程登录用户创建
create user 'hy'@'%' identified by '123456.Com';
grant all privileges on 库名.表明 to 'hy'@'%' with grant options;
flush privileges;
9、命令行操作mysql
mysql -u root -p -e " show databases;"

2、同理在192.168.115.136上安装mysql并验证远程登录账户

mysql -u hy -p'123456.Com' -h 192.168.115.131 -P 3306 -e "show databases;"

三、部署Tomcat

在192.168.115.136/192.168.115.140部署tomcat

java环境Java SE | Oracle Technology Network | Oracle

Tomcat Apache Tomcat® - Welcome!

                                                Java环境部署
1、which Java 查看Java的路径
      Java -version 查看Java版本
      如果版本达不到我们的安装要求就使用rm -rf 配合which java 删除现有版本


2、直接使用rpm -ivh jdk-20_linux-x64_bin.rpm 安装即可
      安装完成后查看which Java
                   Java -version
          

                                                Tomcat部署
Tomcat下载地址 https://tomcat.apache.org/
1、解压
    tar -xf apache-tomcat-9.0.80.tar.gz
    mv apache-tomcat-9.0.80 /usr/local/tomcat
2、建立软联建
     启动命令   ln -s /usr/local/tomcat/bin/startup.sh /usr/bin/catup
     停止命令   ln -s /usr/local/tomcat/bin/shutdown.sh /usr/bin/catdown

启动 catup

四、配置NGINX

192.168.115.141/192.168.115.142安装NGINX配置动静分离，负载均衡

1、安装

yum -y install epel-release.noarch 
yum -y install nginx

2、配置

vim /etc/nginx/nginx.conf
##在http字段插入
upstream tomcat {
                server 192.168.115.136:8080;
                server 192.168.115.140:8080;
        }
##在server字段插入
location ~ \.jsp$ {                                ####这里是jsp
                proxy_pass http://tomcat;
                proxy_set_header  Host $host;
        }
        location / {
                root    /usr/share/nginx/html;
                index   index.html;
        }
###保存退出重启服务

3、测试

分别访问192.168.115.141/192.168.115.142

五、配置NGINX的双机热备提高可用性

yum -y install keepalived
vim /etc/keepalived/keepalived.conf
