安裝Linux用的是騰訊雲的centos7.5，需要安裝有環境有mysql5.7  .netcore2.1 nginx1.14

1.首先是mysql的安裝

我用的連結工具是putty，首先root登入系統

採用yum的方式安裝mysql

1.安裝mysql的yum源

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

2.安裝mysql-community.repo
mysql-community-source.repo依賴包

rpm -ivh mysql57-community-release-el7-8.noarch.rpm

3.安裝mysql

yum install -y mysql-server

安裝完成

4.執行mysql,並檢視執行狀態

service mysqld start
service mysqld status

執行成功

5.由於mysql5.7 會生成一個隨機密碼，所有先檢視密碼 (mysql5.6 也有隨機密碼，5.5不知道)

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

箭頭值得就是隨機密碼，我們記錄下來

6.登入 MySQL並更新使用者 root 的密碼，這裡我們設定了passwordA1.作為新密碼

mysql -u root -p

SET PASSWORD = PASSWORD('passwordA1.');
ALTER USER 'root'@'localhost' PASSWORD EXPIRE NEVER;
flush privileges;

7.設定mysql可以被任意ip訪問和root 本地訪問

grant all privileges on *.* to root@"
 
%" identified by "passwordA1."; 
grant all privileges on *.* to root@"localhost" identified by "passwordA1."; 
flush privileges;

8.MySQL控制命令：啟動、停止、重啟、檢視狀態

service mysqld start
service mysqld stop
service mysqld restart
service mysqld status
systemctl start mysqld
service mysqld stop
service mysqld restart
systemctl status mysqld

9.測試遠端連線

 連線成功！

2. .net core2.1的安裝

參照官方文件，地址:https://www.microsoft.com/net/learn/dotnet/hello-world-tutorial#install

1.新增yum源

sudo rpm -Uvh https://packages.microsoft.com/config/rhel/7/packages-microsoft-prod.rpm

2.升級所有包同時也升級軟體和系統核心

sudo yum update

3.安裝.net core

sudo yum install dotnet-sdk-2.1.4

3. nginx的安裝

1.新增nginx源

sudo rpm -Uvh http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm

2.安裝nginx

sudo yum install nginx

3.啟動nginx並設定開機啟動

sudo systemctl start nginx.service
sudo systemctl enable nginx.service
