【One by one系列】一步步部署.net core应用

咱们的目标:

  • CentOS系统
  • nginx服务器
  • asp.net core应用
  • mysql服务器
  • 腾讯云服务器
  • 工具准备
  • 【Xshell】——使用windwos下的工具Xshell,原理就是使用SHH协议让咱们能够链接其余计算机,相似于windows的远程桌面链接,只是如今用于远程腾讯云主机------------【执行命令】html

  • 【WinSCP】——当咱们的asp.net core网站写好,发布文件完成时,须要往CentOS上拷贝,这时使用WinSCP,当配置好ip,链接上另一遍的CentOS系统,则能够实现两台计算机文件的共享,拷贝----------【文件拷贝】python

  • 【.net core SDK】——.net core 开发的web或webapp在CentOS上可以运行,就须要环境,.net core去官网看,有linux下各版本的下载安装方式-----------【安装.net core】------CentOSmysql

  • 【nginx】——是一个反向代理http服务器,能够转发linux

    【安装】nginx

    curl -o nginx.rpm
    http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm
    rpm -ivh nginx.rpm
    yum install nginx #安装git

    【配置】github

    在 /etc/nginx中
    cd /etc/nginx
    vim nginx.confweb

    • 内容为:
      user nginx;
      worker_processes 1;sql

      error_log  /var/log/nginx/error.log warn;
        pid        /var/run/nginx.pid;
      
        events {
            worker_connections  1024;
        }
      
        http {
            include       /etc/nginx/mime.types;
            default_type  application/octet-stream;
      
            log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                              '$status $body_bytes_sent "$http_referer" '
                              '"$http_user_agent" "$http_x_forwarded_for"';
      
            access_log  /var/log/nginx/access.log  main;
      
            sendfile        on;
            #tcp_nopush     on;
            client_max_body_size  2000m;  #最大限制为2000M --万一你的web须要上传文件或者图片等大文件
      
            keepalive_timeout  65;
      
            #gzip  on;
      
            include /etc/nginx/conf.d/*.conf;
        }

注意最后依据 include ,这个有点像C语言的,意思是这个配置文件是嵌套的,更详细的配置要去 /etc/nginx/conf.d/*.conf里面去找shell

cd /etc/nginx/conf.d/
vim default.conf

内容为下:
    server {
        listen       80;
        server_name  118.24.112.238;

        #charset koi8-r;
        #access_log  /var/log/nginx/host.access.log  main;

        location / {
            proxy_pass http://localhost:5009;
            proxy_http_version 1.1;
        proxy_set_header X-real-ip           $remote_addr;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection keep-alive;
            proxy_set_header Host $host;
            proxy_cache_bypass $http_upgrade;
        proxy_connect_timeout    600;
        proxy_read_timeout       600;
        proxy_send_timeout       600;
        }

        #error_page  404              /404.html;

        # redirect server error pages to the static page /50x.html
        #
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   /usr/share/nginx/html;
        }
    }
    server {
        listen       81;
        server_name  118.24.112.238;

        #charset koi8-r;
        #access_log  /var/log/nginx/host.access.log  main;

        location / {
            proxy_pass http://localhost:5000;
            proxy_http_version 1.1;
        proxy_set_header X-real-ip           $remote_addr;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection keep-alive;
            proxy_set_header Host $host;
            proxy_cache_bypass $http_upgrade;
        }

        #error_page  404              /404.html;

        # redirect server error pages to the static page /50x.html
        #
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   /usr/share/nginx/html;
        }
    }

大概意思就是监听80端口,转5009,监听81端口,转5000,其余待后续补充知识

【重载】

nginx配置文件修改后,请必定不要忘记重载,新手很容易忘,
nginx -s reload
  • 【守护进程】

    nginx安装配置都好了,防火墙80端口开放,dotnet netcore.dll运行,网站打开,80转发至端口5000,这样的确是发布了,可是总不至于每次开机都要执行一次dotnet run ,只是就须要配置守护服务Supervisor,(守护服务-守护进程)======================何谓守护服务,让其一直运行咱们的web,错误时本身处理,本身重启

    【安装】

    yum install python-setuptools
    easy_install supervisor #安装Supervisor

    【配置】

    Supervisor的默认配置文件supervisord.conf  可是没有使用
    自建了一个supervisor目录,

    【cmd】:mkdir /etc/supervisor
    而后把配置文件输出到指定目录:
    【cmd】:echo_supervisord_conf > /etc/supervisor/supervisord.conf #配置Supervisor
    其中supervisord.conf的文件最后:
    ;[include]
    ;files = relative/directory/.ini
    修改成(【注意】去掉;且不能有空格)
    [include]
    files = conf.d/
    .conf
    而后cd /etc/supervisor/
    mkdir conf.d
    新建文件:
    vim zyhopsys.conf
    vim zyhopsys-admin.conf
    文件内容大概为:
    [program:opadmin]
    command=dotnet ZYH.Operation.Sys.Admin.dll #(注意)运行程序的命令
    directory= /home/op-admin/ #(注意 注意)对应的你的项目的存放目录,这个地方好多初学者搞错!!!
    autorestart=true #程序意外退出是否自动重启
    environment=ASPNETCORE_ENVIRONMENT=Production #进程环境变量
    stderr_logfile=/var/log/myproject.err.log; #错误日志文件
    stdout_logfile=/var/log/myproject.out.log; #输出日志文件
    user=root #进程执行的用户身份
    stopsignal=INT
    autostart=true
    autorestart=true
    startsecs=1

    【搭载配置文件运行】

    supervisord -c /etc/supervisor/supervisord.conf
      这里稍微提一句:supervisord的启动顺讯
      supervisord                                   #默认去找$CWD/supervisord.conf,也就是当前目录
      supervisord                                   #默认$CWD/etc/supervisord.conf,也就当前目录下的etc目录
      supervisord                                   #默认去找/etc/supervisord.conf的配置文件
      supervisord -c /home/supervisord.conf         #到指定路径下去找配置文件
    
      运行后:ps -ef | grep dotnet
      能够查看本身的网站是否已运行,正常以下
      root      1877  1817  0 16:40 pts/1    00:00:00 grep --color=auto dotnet
      root      4971 26752  0 13:57 ?        00:00:07 dotnet ZYH.Operation.Sys.Admin.dll
      root      4972 26752  0 13:57 ?        00:00:05 dotnet ZYH.Operation.Sys.Web.dll

    【重载】

    supervisorctl reload  #从新加载
      每次从新部署 后,能够执行一下上面的命令

    【设置开机启动】

    -创建配置文件
      打开目录 /usr/lib/systemd/system/ 新建文件 supervisord.service
      cd /usr/lib/systemd/system/
      vim supervisord.service
      内容:   
      # dservice for systemd (CentOS 7.0+)
      # by ET-CS (https://github.com/ET-CS)
      [Unit]
      Description=Supervisor daemon
    
      [Service]
      Type=forking
      ExecStart=/usr/bin/supervisord -c /etc/supervisor/supervisord.conf
      ExecStop=/usr/bin/supervisorctl shutdown
      ExecReload=/usr/bin/supervisorctl reload
      KillMode=process
      Restart=on-failure
      RestartSec=42s
    
      [Install]
      WantedBy=multi-user.target
      执行命令:
      systemctl enable supervisord 
      systemctl is-enabled supervisord #来验证是否为开机启动
  • 【防火墙】

    若是公网ip访问不了:那是由于CentOs的防火墙拦截了,咱们打开端口。

    firewall-cmd --zone=public --add-port=80/tcp --permanent #(开放80端口)
    systemctl restart firewalld #(重启防火墙以使配置即时生效)

    firewall-cmd --zone=public --add-port=80/tcp --permanent #(开放80端口)
    systemctl restart firewalld #(重启防火墙以使配置即时生效)

    --我在使用腾讯云主机,经过上述命令并不能远程访问mysql

    firewall-cmd --zone=public --add-port=3306/tcp --permanent #(开放3306端口)

    最后改用iptables

    【安装】

    #先检查是否安装了iptables
      service iptables status
      #安装iptables
      yum install -y iptables
      #升级iptables
      yum update iptables
      #安装iptables-services
      yum install iptables-services

    【中止firewalld】

    #中止firewalld服务
      systemctl stop firewalld
      #禁用firewalld服务
      systemctl mask firewalld

    【配置iptables】

    vim /etc/sysconfig/iptables
      # sample configuration for iptables service
      # you can edit this manually or use system-config-firewall
      # please do not ask us to add additional ports/services to this default configuration
      *filter
      :INPUT ACCEPT [0:0]
      :FORWARD ACCEPT [0:0]
      :OUTPUT ACCEPT [0:0]
      -A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT
      -A INPUT -p icmp -j ACCEPT
      -A INPUT -i lo -j ACCEPT
      -A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT
      -A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT
      -A INPUT -m state --state NEW -m tcp -p tcp --dport 81 -j ACCEPT
      -A INPUT -m state --state NEW -m tcp -p tcp --dport 3306 -j ACCEPT
      -A INPUT -m state --state NEW -m tcp -p tcp --dport 23 -j ACCEPT
    
      -A INPUT -j REJECT --reject-with icmp-host-prohibited
      -A FORWARD -j REJECT --reject-with icmp-host-prohibited
      COMMIT
  • 综上,到目前位置,咱们尚未涉及与数据库级别的交互,只是.net core在linux上发布经历的环境配置
  • CentOS的安装
          远程执行终端Xshell
          远程拷贝文件WinSCP
          .net core 环境的安装
          服务器nginx的安装,配置,转发规则配置等
          守护服务Supervisor的安装,自启动
  • 承上启下,之前都是发布,可是咱们的动态网站,必有数据源,咱们选择mysql,mysql经历安装,root帐户登陆,设置密码,

    # wget http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm
      # rpm -ivh mysql-community-release-el7-5.noarch.rpm
      # yum install mysql-community-server

开启权限,开启CentOS防火墙-3306的端口(相似与sqlserver1433端口),重启防火墙,这样咱们就能远程访问mysql

centOS预装了mariadb(mysql之父为了mysql可能存在闭源风险而搞mysql分支)

安装完之后mariadb自动就被替换了,将再也不生效。

 【安装】

    # wget http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm
    # rpm -ivh mysql-community-release-el7-5.noarch.rpm
    # yum install mysql-community-server

 【重启mysql服务】


    # service mysqld restart

 【修改密码】

初次安装mysql,root帐户没有密码。

直接 #mysql -u root

# mysql>show databases;

mysql>set password for 'root'@'localhost' =password('设置你的密码');
Query OK, 0 rows affected (0.00 sec)

不须要重启数据库便可生效。

 【配置】

#vim /etc/my.cnf

内容以下:
    # For advice on how to change settings please see
    # http://dev.mysql.com/doc/refman/5.6/en/server-configuration-defaults.html
    [client]
    default-character-set=utf8
    # 加上 省得有中文乱码

    [mysql]

    [mysqld]

    character-set-server = utf8
    # 加上 省得有中文乱码

    innodb_log_file_size=640M

    max_allowed_packet = 64M 
    #加上,当你有大量数据要往数据库中存储就须要这个配置,例如二进制文件

    #
    # Remove leading # and set to the amount of RAM for the most important data
    # cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
    # innodb_buffer_pool_size = 128M
    #
    # Remove leading # to turn on a very important data integrity option: logging
    # changes to the binary log between backups.
    # log_bin
    #
    # Remove leading # to set options mainly useful for reporting servers.
    # The server defaults are faster for transactions and fast SELECTs.
    # Adjust sizes as needed, experiment to find the optimal values.
    # join_buffer_size = 128M
    # sort_buffer_size = 2M
    # read_rnd_buffer_size = 2M

    datadir=/var/lib/mysql

    socket=/var/lib/mysql/mysql.sock

    # Disabling symbolic-links is recommended to prevent assorted security risks
    symbolic-links=0

    default-storage-engine=InnoDB
    max_connections=151

    # Recommended in standard MySQL setup
    sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

    [mysqld_safe]

    log-error=/var/log/mysqld.log

    pid-file=/var/run/mysqld/mysqld.pid

【远程链接设置】- 我就想在家,在公司,在任何地方都能进入我本身的数据库操做一下,navicat连一下

    #把在全部数据库的全部表的全部权限赋值给位于全部IP地址的root用户。

    mysql> grant all privileges on *.* to root@'%'identified by 'password';

    #若是是新用户而不是root,则要先新建用户

    mysql>create user 'username'@'%' identified by 'password'; 



【重载】

    配置文件修改后,别忘记重启mysql
    service mysqld restart
