    并发网服务器迁移

    本月将并发编程网站迁移到UCloud云服务,本文是迁移的步骤,希望对其他同学有所帮助。

    第一步:安装软件

    软件包括php,mysql和nginx。

    yum -y install ?php php-fpm mysql nginx lighttpd-fastcgi php-cli php-mysql php-gd php-imap php-ldap php-odbc php-pear php-xml php-xmlrpc php-mbstring php-mcrypt php-mssql php-snmp php-soap php-tidy

    第二步:软件配置

    2.1 配置nginx

    vi /etc/nginx/nginx.conf

    user? ? ? ? ? ? www www;
    worker_processes? 8;
    error_log? /var/log/nginx/error.log;
    pid? ? ? ? /var/run/nginx.pid;
    worker_rlimit_nofile 65535;
    events {
    use epoll;
    worker_connections? 65535;
    }
    http {
    include ? ? ? /etc/nginx/mime.types;
    default_type? application/octet-stream;
    log_format? main? '$remote_addr - $remote_user [$time_local] "$request" '
    '$request_time $upstream_response_time'
    '$status $body_bytes_sent "$http_referer" '
    '"$http_user_agent" "$http_x_forwarded_for"';
    server_names_hash_bucket_size 128;
    client_header_buffer_size 32k;
    large_client_header_buffers 4 32k;
    client_max_body_size 10M;
    sendfile on;
    tcp_nopush ? ? on;
    keepalive_timeout 30;
    tcp_nodelay on;
    fastcgi_connect_timeout 300;
    fastcgi_send_timeout 300;
     fastcgi_read_timeout 300;
     fastcgi_buffer_size 64k;
     fastcgi_buffers 4 64k;
     fastcgi_busy_buffers_size 128k;
     fastcgi_temp_file_write_size 128k;
    gzip on;
     gzip_min_length 1k;
     gzip_buffers 4 16k;
     gzip_http_version 1.0;
     gzip_comp_level 2;
     gzip_types text/plain application/x-javascript text/css application/xml;
     gzip_vary on;
    server
     {
     listen 80;
     server_name www.gofansmi6.com www.www.gofansmi6.com;
     index index.html index.htm index.php;
     try_files $uri $uri/ /index.php?q=$uri&$args;
     root /home/www/ifeve;
    #include wp_params_supercache.conf;
    location ~ .*\.(php|php5)?$
     {
     fastcgi_pass 127.0.0.1:9000;
     fastcgi_index index.php;
     include fcgi.conf;
     }
    }
     }
    
    

    2.2 配置php-fpm

    vi /etc/php-fpm.d/www.conf
    ;Start a new pool named 'www'.
     [www]
    ; The address on which to accept FastCGI requests.
     ; Valid syntaxes are:
     ; 'ip.add.re.ss:port' - to listen on a TCP socket to a specific address on
     ; a specific port;
     ; 'port' - to listen on a TCP socket to all addresses on a
     ; specific port;
     ; '/path/to/unix/socket' - to listen on a unix socket.
     ; Note: This value is mandatory.
     listen = 127.0.0.1:9000
    ; Set listen(2) backlog. A value of '-1' means unlimited.
     ; Default Value: -1
     listen.backlog = 102400
    ; List of ipv4 addresses of FastCGI clients which are allowed to connect.
     ; Equivalent to the FCGI_WEB_SERVER_ADDRS environment variable in the original
     ; PHP FCGI (5.2.2+). Makes sense only with a tcp listening socket. Each address
     ; must be separated by a comma. If this value is left blank, connections will be
     ; accepted from any ip address.
     ; Default Value: any
     listen.allowed_clients = 127.0.0.1,120.132.54.203,115.192.118.9
    ; Set permissions for unix socket, if one is used. In Linux, read/write
     ; permissions must be set in order to allow connections from a web server. Many
     ; BSD-derived systems allow connections regardless of permissions.
     ; Default Values: user and group are set as the running user
     ; mode is set to 0666
     ;listen.owner = nobody
     ;listen.group = nobody
     listen.mode = 0666
    ; Unix user/group of processes
     ; Note: The user is mandatory. If the group is not set, the default user's group
     ; will be used.
     /pi
     ; be killed. This option should be used when the 'max_execution_time' ini option
     ; does not stop script execution for some reason. A value of '0' means 'off'.
     ; Available units: s(econds)(default), m(inutes), h(ours), or d(ays)
     ; Default Value: 0
     request_terminate_timeout = 3s
    ; The timeout for serving a single request after which a PHP backtrace will be
     ; dumped to the 'slowlog' file. A value of '0s' means 'off'.
     ; Available units: s(econds)(default), m(inutes), h(ours), or d(ays)
     ; Default Value: 0
     request_slowlog_timeout = 3s
    ; The log file for slow requests
     ; Default Value: not set
     ; Note: slowlog is mandatory if request_slowlog_timeout is set
     slowlog = /var/log/php-fpm/www-slow.log
    ; Set open file descriptor rlimit.
     ; Default Value: system defined value
     rlimit_files = 102400
    ; Set max core size rlimit.
     ; Possible Values: 'unlimited' or an integer greater or equal to 0
     ; Default Value: system defined value
     rlimit_core = 0
    ; Chroot to this directory at the start. This value must be defined as an
     ; absolute path. When this value is not set, chroot is not used.
     ; Note: chrooting is a great security feature and should be used whenever
     ; possible. However, all PHP paths will be relative to the chroot
     ; (error_log, sessions.save_path, ...).
     ; Default Value: not set
     ;chroot =
    ; Chdir to this directory at the start. This value must be an absolute path.
     ; Default Value: current directory or / when chroot
     ;chdir = /var/www

    第三步:迁移数据和网站

    3.1 迁移数据库

    • 在旧服务器中导出ifeve数据库:mysql -f -h localhost -uroot -pifevepassword ?ifeve > ifevedb_backup.sql
    • 在新服务器中设置新mysql的默认密码:mysqladmin?-u?root?password?123
    • 在新服务器中创建ifeve数据库:mysqladmin -h?localhost -u root -p create ifeve
    • 在新服务器中导入ifeve数据库:mysql -f -h localhost -uroot -pifevepassword ?ifeve < ifevedb_backup.sql

    3.2 迁移网站

    scp -r 192.168.0.1:/home/www/ifeve ?192.168.0.2:/home/www/

    3.3 设置目录权限

    • chown -R? www.www /home/www/ifeve
    • chmod -R 755 /home/www/ifeve

    第四步:启动应用

    • service php-fpm restart
    • service nginx restart
    • service mysqld restart

    恭喜你迁移完成。

    查询各种日志

    • tail -fn 5 /var/log/nginx/error.log
    • tail -fn 5 /var/log/nginx/access.log
    • tail -fn 500 /var/log/php-fpm/error.log
    • tail -fn 5?/var/log/php-fpm/www-slow.log

      有没有可能通过docker运行,这样下次换服务商更方便
