GCE porting recommandation

GCE是Google Cloud Platform上提供虛擬主機服務的一員，承襲了Google的強大，提供了無限量的環境與相當快速的網路，Management Portal的操作設計也相當便捷，這邊有機會做一個PHP專案的Porting，順手針對Porting GCE上面的PHP程式做了個記錄，目標是Porting到一台CentOS主機，記錄的幾點注意事項，給大家參考：

• Install LAMP
  $ sudo yum  -y  install  httpd  php  php-mysql  mysql  mysql-server
  $ sudo yum install php-mysql php-gd libjpeg* php-imap php-ldap php-odbc php-pear php-xml php-xmlrpc php-mbstring php-mcrypt php-bcmath php-mhash libmcrypt
• FW configure (GCE default enabled the iptables)
  $ sudo vi /etc/sysconfig/iptables
  ⇒ Add your port… link 80, 443...
• SELinux setting (GCE default enable the SELinux)
  $ sudo vi /etc/sysconfig/selinux
  ⇒ SELINUX=disabled
• Create persistence disk (GCE default root disk is only 10GB)

$ df -h

Filesystem      Size  Used Avail Use% Mounted on

/dev/sda1       9.9G  9.9G     0 100% /

tmpfs           1.8G     0  1.8G   0% /dev/shm

$ sudo mkdir -p /mnt/pd0

$ ls -l /dev/disk/by-id/google-*

lrwxrwxrwx. 1 root root  9 2013-12-23 06:55 /dev/disk/by-id/google-php-server -> ../../sda

lrwxrwxrwx. 1 root root  9 2013-12-23 11:22 /dev/disk/by-id/google-php-server-data-disk1 -> ../../sdb

lrwxrwxrwx. 1 root root 10 2013-12-23 06:55 /dev/disk/by-id/google-php-server-part1 -> ../../sda1

$ sudo /usr/share/google/safe_format_and_mount -m "mkfs.ext4 -F" /dev/disk/by-id/google-php-server-data-disk1 /mnt/pd0

safe_format_and_mount: Running: fsck.ext4 -a /dev/disk/by-id/google-php-server-data-disk1

safe_format_and_mount: fsck.ext4: Bad magic number in super-block while trying to open /dev/disk/by-id/google-php-server-data-disk1

safe_format_and_mount: /dev/disk/by-id/google-php-server-data-disk1:

safe_format_and_mount: The superblock could not be read or does not describe a correct ext2

safe_format_and_mount: ....

safe_format_and_mount: This filesystem will be automatically checked every 21 mounts or

safe_format_and_mount: 180 days, whichever comes first.  Use tune2fs -c or -i to override.

safe_format_and_mount: Running: mount -o defaults /dev/disk/by-id/google-php-server-data-disk1 /mnt/pd0

$ sudo mount -o defaults /dev/disk/by-id/google-php-server-data-disk1 /mnt/pd0

mount: /dev/sdb already mounted or /mnt/pd0 busy

mount: according to mtab, /dev/sdb is already mounted on /mnt/pd0

• Mount persistence disk when boot

$ sudo vi /etc/fstab

UUID=a8cf...aaf98 / ext4    defaults,barrier=0 1 1

tmpfs         /dev/shm      tmpfs   defaults        0 0

devpts        /dev/pts      devpts  gid=5,mode=620  0 0

sysfs         /sys          sysfs   defaults        0 0

proc          /proc         proc    defaults        0 0 /dev/sdb /mnt/pd0 ext4 defaults 1 1

• Setup boot level services

$ sudo chkconfig --level 23456 mysqld on
$ sudo chkconfig --level 23456 httpd on
