ownCloud 4.0.0 on CentOS6.2

インストール自体は結構簡単でした。こんな感じで、インストール出来ると思われます。

MySQL/Apache/PHPはインストールされている物として話を進めています。入ってなかっら、yum か add/remove software から追加してください。

準備

  1. iptables と selinux を停止(無効化)
  2. 開発環境の導入
  3. 作業用ディレクトリの作成
  4. パッケージのダウンロード

[root@centos6 ~]# service iptables stop

[root@centos6 ~]# chkconfig iptables off

SELinuxの制限を解除

[root@centos6 ~]# setenforce Permissive

次回再起動から、SELinuxが無効の状態で起動してくるように設定

[root@centos6 ~]# vi /etc/sysconfig/selinux

##SELINUX=enforcing

SELINUX=disabled

開発環境の導入

[root@centos6 ~]# yum -y groupinstall "Development Tools"

[root@centos6 ~]# mkdir owncloud

[root@centos6 ~]# cd owncloud/

[root@centos6 owncloud]# wget http://owncloud.org/owncloud-download-4-0-0

ownCloudのインストール

関連パッケージの導入

[root@centos6 owncloud]# yum -y install php php-xml php-mbstring php-gd php-mysql php-pear php-devel

[root@centos6 owncloud]# yum -y install libzip libzip-devel zlib-devel

[root@centos6 owncloud]# yum -y install pcre pcre-devel

[root@centos6 owncloud]# pecl install zip

[root@centos6 owncloud]# vi /etc/php.ini

extension=zip.so            <- この設定を追加(938行目に追加しました)

ownCloudの導入

[root@centos6 owncloud]# tar jxf owncloud-4.0.0.tar.bz2

[root@centos6 owncloud]# cp -r owncloud /var/www/

[root@centos6 owncloud]# chown -R apache:apache /var/www/owncloud/


MySQLの準備

[root@centos6 owncloud]# cd /etc

[root@centos6 etc]# cp my.cnf my.cnf.org

[root@centos6 etc]# cp /usr/share/mysql/my-medium.cnf my.cnf

cp: `my.cnf' を上書きしてもよろしいですか(yes/no)? y

[root@centos6 etc]# vi my.cnf

# Example MySQL config file for medium systems.

#

# This is for a system with little memory (32M - 64M) where MySQL plays

# an important part, or systems up to 128M where MySQL is used together with

# other programs (such as a web server)

#

# MySQL programs look for option files in a set of

# locations which depend on the deployment platform.

# You can copy this option file to one of those

# locations. For information about these locations, see:

# http://dev.mysql.com/doc/mysql/en/option-files.html

#

# In this file, you can use all long options that a program supports.

# If you want to know which options a program supports, run the program

# with the "--help" option.

# The following options will be passed to all MySQL clients

[client]

#password       = your_password

port            = 3306

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

default-character-set = utf8

# Here follows entries for some specific programs

# The MySQL server

[mysqld]

# Don't listen on a TCP/IP port at all. This can be a security enhancement,

# if all processes that need to connect to mysqld run on the same host.

# All interaction with mysqld must be made via Unix sockets or named pipes.

# Note that using this option without enabling named pipes on Windows

# (via the "enable-named-pipe" option) will render mysqld useless!

# Replication Master Server (default)

# binary logging is required for replication

log-bin=mysql-bin

# binary logging format - mixed recommended

binlog_format=mixed

# required unique id between 1 and 2^32 - 1

# defaults to 1 if master-host is not set

# but will not function as a master if omitted

server-id       = 1

# Replication Slave (comment out master section to use this)

#

# To configure this host as a replication slave, you can choose between

# two methods :

#

# 1) Use the CHANGE MASTER TO command (fully described in our manual) -

#    the syntax is:

#

#    CHANGE MASTER TO MASTER_HOST=<host>, MASTER_PORT=<port>,

#    MASTER_USER=<user>, MASTER_PASSWORD=<password> ;

#

#    where you replace <host>, <user>, <password> by quoted strings and

#    <port> by the master's port number (3306 by default).

#

#    Example:

#

#    CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306,

#    MASTER_USER='joe', MASTER_PASSWORD='secret';

#

# OR

#

# 2) Set the variables below. However, in case you choose this method, then

#    start replication for the first time (even unsuccessfully, for example

#    if you mistyped the password in master-password and the slave fails to

#    connect), the slave will create a master.info file, and any later

#    change in this file to the variables' values below will be ignored and

#    overridden by the content of the master.info file, unless you shutdown

#    the slave server, delete master.info and restart the slaver server.

#    For that reason, you may want to leave the lines below untouched

#    (commented) and instead use CHANGE MASTER TO (see above)

#

# required unique id between 2 and 2^32 - 1

# (and different from the master)

# defaults to 2 if master-host is set

# but will not function as a slave if omitted

#server-id       = 2

#

# The replication master for this slave - required

#master-host     =   <hostname>

#

# The username the slave will use for authentication when connecting

# to the master - required

#master-user     =   <username>

#

# The password the slave will authenticate with when connecting to

# the master - required

#master-password =   <password>

#

# The port the master is listening on.

# optional - defaults to 3306

#master-port     =  <port>

#

# binary logging - not required for slaves, but recommended

#log-bin=mysql-bin

# Uncomment the following if you are using InnoDB tables

#innodb_data_home_dir = /var/lib/mysql

#innodb_data_file_path = ibdata1:10M:autoextend

#innodb_log_group_home_dir = /var/lib/mysql

# You can set .._buffer_pool_size up to 50 - 80 %

# of RAM but beware of setting memory usage too high

#innodb_buffer_pool_size = 16M

Apacheの設定

/var/www/owncloud を / として、apacheが動作するように設定します。

[root@centos6 ~]# vi /etc/httpd/conf/httpd.conf

##DocumentRoot "/var/www/html"

DocumentRoot "/var/www/owncloud"

##<Directory "/var/www/html">

<Directory "/var/www/owncloud">

[root@centos6 ~]# service httpd start


ownCloudの設定

これで、ownCloudを実行する準備が整いました。以下の手順で、ownCloudの設定を行ってください。

  1. Webにアクセス

  1. ownCloudの管理アカウント/パスワードを指定
  2. Advanced を選択
  3. MySQLを選択
  4. DBのパラメタを設定
  5. Finish setup をクリック


サービスの自動起動設定

システム起動時に、MySQLとApacheが自動的に起動してくるように設定します。

[root@centos6 ~]# chkconfig httpd on

[root@centos6 ~]# chkconfig mysqld on


設定変更

大きなファイルのアップロードを許可する

標準では、phpで2MBに制限されている

php.ini に以下のような設定を行う事でアップロードサイズを変更できます。

また、一度にアップロードできるファイル数にも制限があります。これも、同様に設定を調整してください。

php.iniをこんな感じに編集して、httpdを再起動する。

[root@centos6 etc]# vi /etc/php.ini

 727 ; Maximum size of POST data that PHP will accept.

 728 ; http://www.php.net/manual/en/ini.core.php#ini.post-max-size

 729 ;;post_max_size = 8M

 730 post_max_size = 100M

 877 ; Maximum allowed size for uploaded files.

 878 ; http://www.php.net/manual/en/ini.core.php#ini.upload-max-filesize

 879 ;;upload_max_filesize = 2M

 880 upload_max_filesize = 80M

 882 ; Maximum number of files that can be uploaded via a single request

 883 ;;max_file_uploads = 20

 884 max_file_uploads = 1024  ファイル数制限も大きな値に変更

[root@centos6 etc]# service httpd restart
