### 在Linux上的项目环境搭建 ###

*   *   *  1. 安装jdk
         *  2. 安装Tomcat
         *  3. 安装mysql

--------------------

**官网下载VMware：**[https://www.vmware.com/cn/products/workstation-pro/workstation-pro-evaluation.html][https_www.vmware.com_cn_products_workstation-pro_workstation-pro-evaluation.html]

**密钥：UY758-0RXEQ-M81WP-8ZM7Z-Y3HDA**

**CentOS 7官网下载：**[https://www.centos.org/download/][https_www.centos.org_download]

**阿里云镜像下载：**[http://mirrors.aliyun.com/centos/7/isos/x86\_64/][http_mirrors.aliyun.com_centos_7_isos_x86_64]

--------------------

### 1. 安装jdk ###

**1. 首先需要卸载系统自带的jdk**

rpm -qa | grep jdk
    
    rpm -e --nodeps java-1.8.0-openjdk-headless-1.8.0.242.b08-1.el7.x86_64
    
    rpm -e --nodeps copy-jdk-configs-3.3-10.el7_5.noarch
    
    rpm -e --nodeps java-1.8.0-openjdk-1.8.0.242.b08-1.el7.x86_64

**2. 在/usr/local/下创建java目录，传输jdk的rpm包至该路径，用以下命令安装：**

rpm -ivh jdk-8u221-linux-x64.rpm

**3. 配置环境变量**

vi /etc/profile

JAVA_HOME=/usr/java/jdk1.8.0_221-amd64
    CLASSPATH=%JAVA_HOME%/lib:%JAVA_HOME%/jre/lib
    PATH=$PATH:$JAVA_HOME/bin:$JAVA_HOME/jre/bin
    export PATH CLASSPATH JAVA_HOME

**4. 让环境变量配置生效**

source /etc/profile

--------------------

### 2. 安装Tomcat ###

**1. 在/usr/local/下创建tomcat目录，传送tomcat包至该路径并解压：**

tar -zxvf apache-tomcat-9.0.34.tar.gz

**2. 进入bin目录，启动tomcat**

./startup.sh

**3. 开放8080端口**

*  **检测防火墙状态，如果是关闭状态，需要先开启防火墙**

firewall-cmd --state

*  **开启防火墙**

systemctl start firewalld.service

*  **开启端口**

firewall-cmd --zone=public --add-port=8080/tcp --permanent

*  **重启防火墙**

systemctl restart firewalld.service

*  **重新载入配置**

firewall-cmd --reload

--------------------

### 3. 安装mysql ###

**1. 在/usr/local/下创建mysql目录，传送mysql包并解压：**

tar -xvf mysql-8.0.20-1.el7.x86_64.rpm-bundle.tar

**2. 删除自带的mariadb**

查看mariadb
    rpm -qa |grep mariadb
    强制删除mariadb
    rpm -e mariadb-libs-5.5.65-1.el7.x86_64 --nodeps

**3. 安装4个：common、libs、client、server**

rpm -ivh mysql-community-common-8.0.20-1.el7.x86_64.rpm --nodeps --force
    rpm -ivh mysql-community-libs-8.0.20-1.el7.x86_64.rpm --nodeps --force
    rpm -ivh mysql-community-client-8.0.20-1.el7.x86_64.rpm --nodeps --force
    rpm -ivh mysql-community-server-8.0.20-1.el7.x86_64.rpm --nodeps --force

**4. 初始化mysql**

mysqld --initialize
    
    如果报错：mysqld: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory
    
    yum install -y libaio

**5. 授权防火墙**

chown mysql:mysql /var/lib/mysql -R
    systemctl start mysqld.service
    systemctl enable mysqld

**6. 查看数据库初始化密码**

cat /var/log/mysqld.log | grep password
    
    =wy727d4A%.?

**7. 登录数据库**

mysql -uroot -p
    =wy727d4A%.?

**8. 修改密码**

ALTER USER "root"@"localhost" IDENTIFIED BY "123456";

**9. 开启远程访问**

create user "root"@"%" identified with mysql_native_password by "123456";
    
    grant all privileges on *.* to "root"@"%" with grant option; 
    
    flush privileges;

**10. 开放3306端口**

firewall-cmd --zone=public --add-port=3306/tcp --permanent
    systemctl restart firewalld.service
    firewall-cmd --reload

**11. 时区+8**

set global time_zone="+8:00";
