浪潮云服务器部署(一)

# cd /home

# mkdir java

# mkdir jenkins

# mkdir maven

# mkdir mysql

# mkdir nginx

# mkdir nodejs

# mkdir zip

[root@ecs-20210811210238 home]# ls

java jenkins maven mysql nginx nodejs zip

1.yum安装ntpdate工具。

# yum -y install ntp ntpdate

2.设置系统时间与网络时间同步。

# ntpdate cn.pool.ntp.org

3.将系统时间写入硬件时间

# hwclock --systohc

5. 强制系统时间写入CMOS中。

# hwclock -w

6. 设置时区

echo "Asia/shanghai" > /etc/timezone

查看时间

cat /etc/localtime

查看时区

cat /etc/timezone

yum -y install lrzsz

yum -y install vim

1.下载压缩包

jdk-8u191-linux-x64.tar.gz

2.上传压缩包到centos7服务器

/home

3.解压压缩包文件

tar -zxvf jdk-8u191-linux-x64.tar.gz

4.配置环境变量

vim /etc/profile

#在文件末尾插入如下内容

export JAVA_HOME=/home/java/jdk1.8.0_191

export JRE_HOME=${JAVA_HOME}/jre

export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib

export PATH=${JAVA_HOME}/bin:$PATH

#执行profile

#source /etc/profile

5.检查jdk是否生效

java -version

javac -version

7. 安装mysql5.7

1. wget http://repo.mysql.com/mysql57-community-release-el7-10.noarch.rpm

2. rpm -Uvh platform-and-version-specific-package-name.rpm

3. yum install -y mysql-community-server

4. service mysqld start

5. service mysqld status

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

7. mysql -h 127.0.0.1 -u root -p 123456

8. mysql> use mysql;

9. mysql> update user set password=password('123') where user='root' and host='localhost';

10. mysql> flush privileges;

mysql> set global validate_password_policy=0;

再修改密码的长度

set global validate_password_length=6;

再次执行修改密码就可以了

8、授权其他机器登陆

ALTER USER 'root'@'localhost' IDENTIFIED BY '123';

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123' WITH GRANT OPTION;

FLUSH PRIVILEGES;

mysql> exit

1. vim /etc/my.cnf

# skip-grant-tables

lower_case_table_names=1

2. 设置开机启动

[root@localhost local]# systemctl enable mysqld

[root@localhost local]# systemctl daemon-reload

3. 启动mysql 服务

[root@localhost local]# systemctl start mysqld

4. mysql 在centos7.8 中开放3306端口

firewall-cmd --zone=public --add-port=3306/tcp --permanent

firewall-cmd --reload

firewall-cmd --list-ports
