CentOS7搭建Java环境（JDK、MySQL和Tomcat）

目录

安装jdk

准备

  1. jdk的tar.gz包(本文准备的版本是jdk-8u212-linux-x64.tar.gz)
  2. 通过xftp上传到/opt/software下

jdk环境配置流程

  1. 解压到/opt/modules目录下
    tar -zxvf jdk-8u212-linux-x64.tar.gz -C /opt/modules
  2. 进入解压目录下并打印路径
    cd /opt/modules/jdk1.8.0_212
    pwd
    在这里插入图片描述
  3. 修改环境变量
    sudo vim /etc/profile
    或使用root账户
    在文件末尾添加环境变量
    JAVA_HOME=/opt/modules/jdk1.8.0_212  
PATH=$JAVA_HOME/bin:$PATH  
export JAVA_HOME PATH
    在这里插入图片描述
  4. 配置文件立即生效

安装MySQL 5.6

准备

  1. mysql的源码tar.gz包(本文准备的版本是mysql-5.6.44.tar.gz)
  2. 通过xftp上传到/opt/software下

MySQL安装流程

  1. 解压到modules目录下
    tar -zxvf mysql-5.6.44.tar.gz -C /opt/modules/
  2. 卸载旧版本
    rpm -qa | grep mysql
    rpm -e mysql_libs（普通删除）或rpm -e --nodeps mysql_libs（强力删除）
  3. 安装编译代码需要的包
    yum -y install make gcc-c++ cmake bison-devel ncurses-devel
  4. 编译源码包（这是一条命令）
    cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_DATADIR=/usr/local/mysql/data -DSYSCONFDIR=/etc -DWITH_MYISAM_STORAGE_ENGINE=1 -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_MEMORY_STORAGE_ENGINE=1 -DWITH_READLINE=1 -DMYSQL_UNIX_ADDR=/var/lib/mysql/mysql.sock -DMYSQL_TCP_PORT=3306 -DENABLED_LOCAL_INFILE=1 -DWITH_PARTITION_STORAGE_ENGINE=1 -DEXTRA_CHARSETS=all -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci
  5. 编译并安装
    make && make install
  6. 新建mysql用户组和用户
    groupadd mysql
    useradd -g mysql mysql
  7. 修改/usr/local/mysql权限
    chown -R mysql:mysql /usr/local/mysql
  8. 初始化配置
    进入安装路径，执行初始化配置脚本，创建系统自带的数据库和表
    cd /usr/local/mysql
    scripts/mysql_install_db --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --user=mysql
  9. 添加服务，拷贝服务脚本到init.d目录，并设置开机启动
    在/usr/local/mysql下执行
    cp support-files/mysql.server /etc/init.d/mysql
    chkconfig mysql on
    service mysql start
  10. 修改root密码
    cd /usr/local/mysql/bin
    ./mysql -uroot
    SET PASSWORD = PASSWORD('密码');
    在这里插入图片描述
  11. 允许远程连接
    update user set host = '%' where user = 'root';
  12. 开发端口
    • 查看已开放端口
      firewall-cmd --zone=public --list-ports
    • 开放端口
      firewall-cmd --zone=public --add-port=3306/tcp --permanent
    • 关闭端口
      firewall-cmd --zone=public --remove-port=3306/tcp --permanent
    • 重启防火墙
      firewall-cmd --reload

安装Tomcat 7

准备

  1. tomcat的tar.gz包(本文准备的版本是apache-tomcat-7.0.93.tar.gz)
  2. 通过xftp上传到/opt/software下

Tomcat安装流程

  1. 解压到modules目录下
    tar -zxvf apache-tomcat-7.0.93.tar.gz -C /opt/modules/
  2. 进入conf目录修改配置
    cd /opt/modules/apache-tomcat-7.0.93/conf
    • 初始化管理员账号
      <?xml version='1.0' encoding='utf-8'?>
<tomcat-users>
	<role rolename="manager-gui"/>
	<role rolename="manager-script" />
	<user username="daye" password="luyuhao2010" roles="manager-gui, manager-script"/>
</tomcat-users>
    • 优化tomcat配置
