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
   
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  
   

   
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‘);
    
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
