JDK-8（java环境）

• 安装java

yum -y install java-1.8.0-openjdk-devel.x86_64

• 环境变量

vim /etc/profile

JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.262.b10-0.el7_8.x86_64/JRE_HOME=$JAVA_HOME/jre
PATH=$PATH:$JAVA_HOME/bin
CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

• 更新环境变量

source /etc/profile

• 查看版本

java -version

Mysql-5.7

• Mysql-yum源下载安装

wget http://repo.mysql.com/mysql57-community-release-el7-8.noarch.rpm
rpm -ivh mysql57-community-release-el7-8.noarch.rpm
yum install mysql-server

• 启动、关闭、查看状态

systemctl start mysqld
systemctl stop mysqld
//注意有些会自动升级MySQL版本，一定要确定是5.7
systemctl status mysqld

• 查看mysql数据库默认密码

grep "password" /var/log/mysqld.log

• 授权远程访问

systemctl start mysqld
mysql -uroot -p
输入上一步查询的默认密码，不行的话直接按回车

• 设置密码级别、长度、密码

//密码级别
set global validate_password_policy=LOW; 
//密码长度6
set global validate_password_length=6;
//6位密码   P@SSwrd
SET PASSWORD = PASSWORD('P@SSw0rd');

• 授权远程访问

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

• 查看账户远程权限配置

use mysql;
select host,user from user;

Redis-6

• 安装依赖

yum -y install centos-release-scl
yum -y install devtoolset-9-gcc devtoolset-9-gcc-c++ devtoolset-9-binutils
gcc版本低解决，最好是都执行一遍
yum install centos-release-scl scl-utils-build
yum install -y devtoolset-8-toolchain
scl enable devtoolset-8 bash

• 下载redis安装包

wget https://download.redis.io/releases/redis-6.2.5.tar.gz

• 解压

tar zxvf redis-6.2.5.tar.gz

• 源码安装

cd redis-6.2.5/
make install

• 创建配置文件

sudo mkdir /etc/redis
cp redis.conf /etc/redis/
mkdir -p /data/6379
mkdir -p /data/6379/log

• 配置文件修改

vim /etc/redis/redis.conf

logfile "/data/6379/log/redis.log"
rdbchecksum yes
dir /data/6379/
#  requirepass 密码，建议和数据库一致
requirepass P@SSw0rd
#bind 127.0.0.1 -::1

• 后台启动

nohup redis-server /etc/redis/redis.conf &

• 关闭

//获取id
netstat -lntp
kill id

服务器添加端口6379

Docker

• yum 包更新到最新

yum update

• 安装需要的软件包， yum-util 提供yum-config-manager功能，另外两个是devicemapper驱动依赖

yum install -y yum-utils device-mapper-persistent-data lvm2

• 设置yum源

yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

• 安装docker，出现输入的界面都按 y

yum install -y docker-ce

docker -v

• 镜像加速器
  阿里云镜像获取地址：https://cr.console.aliyun.com/cn-hangzhou/instances/mirrors，登陆后，左侧菜单选中镜像加速器就可以看到你的专属地址了：
  在/etc/docker/daemon.json，文件末尾增加如下内容

{
 "registry-mirrors": ["https://你的ID.mirror.aliyuncs.com"]
}

• 进程相关命令

启动docker服务:
systemctl start docker
停止docker服务:
systemctl stop docker
重启docker服务:
systemctl restart docker
查看docker服务状态:
systemctl status docker
设置开机启动docker服务:
systemctl enable docker
