首先上传jdk-8u11-linux-x64.tar.gz包到root目录
网盘提取码：hst0

ssh登陆服务器

mkdir /usr/local/java

cp /root/jdk-8u11-linux-x64.tar.gz /usr/local/java/

cd /usr/local/java/

tar xvf jdk-8u11-linux-x64.tar.gz

vi /etc/profile

在尾部加入

export JAVA_HOME=/usr/local/java/jdk1.8.0_11
export JRE_HOME=/usr/local/java/jdk1.8.0_11/jre
export PATH=$PATH:/usr/local/java/jdk1.8.0_11/bin
export CLASSPATH=./:/usr/local/java/jdk1.8.0_11/lib:/usr/local/java/jdk1.8.0_11/jre/lib

重启服务器执行java -version

表示安装成功。
如果发现版本不对

rm -rf /usr/bin/java

rm -rf /usr/bin/javac

ln -s $JAVA_HOME/bin/java /usr/bin/java

ln -s $JAVA_HOME/bin/javac /usr/bin/javac

下面安装mysql5.7

wget http://dev.mysql.com/get/mysql57-community-release-el7-8.noarch.rpm

yum localinstall mysql57-community-release-el7-8.noarch.rpm

yum install mysql-community-server --nogpgcheck

注意带上–nogpgcheck

设置开机启动mysql服务

systemctl enable mysqld 

systemctl daemon-reload

查看mysql启动状态

systemctl restart mysqld.service

systemctl status mysqld.service

表示启动成功

查看MySQL初始密码,这个密码是随机生成的

grep 'A temporary password' /var/log/mysqld.log

// 重制密码
会有弱密码提示，建议设置复杂点或者自己配置关闭

ALTER USER 'root'@'localhost' IDENTIFIED BY 'root';

开启log_bin
查看是否开启

show variables like '%log_bin%';

以上图片成功的开启
没有
vi /etc/my.cnf

末尾加入
#开启并指定二进制日志前缀
log-bin=mysql_bin
#唯一id
server-id=11313
#二进制日志保存时间
expire_logs_days=7
binlog_format=ROW

保存重启mysql

systemctl restart mysqld.service
