Posted on by hackdl

目录

docker安装

 JDK安装

redis安装

nacos控制台安装 

sentinel控制台安装 

rocketmq环境搭建 

fastdfs安装

mysql安装

mycat安装

docker安装

yum -y install docker 安装
systemctl start docker 启动
systemctl restart docker 重启
systemctl stop docker 停止
systemctl enable docker 开机自启

前方有坑———如果你在 docker 运行期间操作了防火墙[启动或关闭]必须重启

docker systemctl restart docker

编辑配置文件

vi /etc/docker/daemon.json

拷贝下面的内容/etc/docker/daemon.json 中

{ "registry-mirrors":
["https://32xw0apq.mirror.aliyuncs.com"] }
systemctl daemon-reload
systemctl restart docker

 JDK安装

安装JDK11

如果是tar.gz文件，则执行解压缩命令

tar -zxvf jdk-11.0.11_linux-x64_bin.tar.gz

解压缩后，默认安装在当前目录下

在/etc/profile文件中设置java环境变量

输入命令检查安装是否完成

java -version

 出现上面的提示，表示jdk安装正常

redis安装

使用 docker 运行 redis

docker run -d --name redis -p 6390:6379 redis --requirepass "123456"

安装完成后，查看redis进程，如上图所示则安装正常

nacos控制台安装 

下载nacos压缩包，使用下面的命令解压缩

tar -zxvf nacos-server-1.2.0.tar.gz

进入nacos安装路径下的bin目录执行启动命令

./startup.sh -m standalone

 使用ps命令查看进程情况

 输入http://你的ip:8848，启动nacos控制台

sentinel控制台安装 

下载sentinel-dashboard-1.8.2.jar包，在jar包所在目录打开命令行窗口，执行以下命令启动控制台

java -jar sentinel-dashboard-1.8.2.jar

 输入默认用户名、密码sentinel，进入主界面

rocketmq环境搭建 

环境要求

JDK 11.0.5

4G+ free

可使用wget命令下载、解压缩并安装

wget
https://archive.apache.org/dist/rocketmq/4.5.1/
rocketmq-all-4.5.1-bin-release.zip

修改脚本

bin/runserver.sh

bin/runbroker.sh

bin/tools.sh

进入rocketmq目录，启动nameserver

nohup sh mqnamesrv > /dev/null 2>&1 &

然后启动broker

nohup sh mqbroker -n localhost:9876 > /dev/null
2>&1 &

fastdfs安装

1、下载fastdfs镜像

docker pull registry.cn-beijing.aliyuncs.com/tianzuo/fastdfs

2、启动镜像

docker run -d --restart=always --
privileged=true --net=host --name=fastdfs -e
IP=192.168.139.128 -e WEB_PORT=8888 -v
${HOME}/fastdfs:/var/local/fdfs registry.cn-beijing.aliyuncs.com/tianzuo/fastdfs

3、查看镜像

docker ps -a

5、测试上传

vim /etc/fdfs/client.conf
#需要修改的内容如下
base_path=/home/fastdfs
#tracker服务器IP和端口
tracker_server=192.168.139.128:22122
#保存后测试,返回ID表示成功 如：group1/M00/00/00/xxx.png
/usr/bin/fdfs_upload_file /etc/fdfs/client.conf /root/fastdfs/1.png

mysql安装

下载必要的安装文件,按顺序执行安装命令，完成后初始化mysql， 修改初始密码

下载必要的安装文件,按顺序执行安装命令，完成后初始化mysql， 修改初始密码

先移除mariadb，再安装 解压缩mysql-5.7.28-1.el7.x86_64.rpm-bundle.tar，解压完成后会 生成一系列rpm安装包，安装的顺序是 1）mysql-community-common-5.7.28-1.el7.x86_64.rpm 2）mysql-community-libs-5.7.28-1.el7.x86_64.rpm 3）mysql-community-libs-compat-5.7.28-1.el7.x86_64.rpm 4）mysql-community-client-5.7.28-1.el7.x86_64.rpm 5）mysql-community-server-5.7.28-1.el7.x86_64.rpm 6）mysql-community-devel-5.7.28-1.el7.x86_64.rpm 

初始化mysql 

mysqld --initialize --user=mysql

查看初始密码

cat /var/log/mysqld.log

进入mysql，修改初始密码

>mysql -uroot -p
>set password=password('123456');

mycat安装

下载Mycat-server-1.6.7.5-release-linux.tar.gz，解压后进入 mycat/bin目录，执行启动命令

./mycat start 启动
./mycat stop 停止
./mycat restart 重启
./mycat status 查看状态

访问mycat，连接成功后和操作mysql一样

mysql -uroot -proot -h127.0.0.1 -P8066

mysql主从搭建

后面再细说

读写分离配置

后面再细说

idea安装

自行下载安装，项目中使用的是2020.2版本
