他の人の経験を参考にして、自分の理解を加えて、次の動作を完成します.
【ソースインストールmysql-5.6.10】
(1)mysqlソースコードの解凍
(2)mysqlのインストールディレクトリおよびデータベース格納ディレクトリの作成
(3)mysqlユーザおよびユーザグループの作成
以前に一度インストールしたことがあるので、ユーザーグループとユーザーはすでに存在します.
(4)mysqlのインストール
パラメータの説明:
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql//インストールディレクトリ
-DINSTALL_DATADIR=/usr/local/mysql/data//データベース格納ディレクトリ
-DDEFAULT_CHARSET=utf 8//utf 8文字を使用
-DDEFAULT_COLLATION=utf8_general_ci//チェック文字
-DEXTRA_CHARSETS=all//すべての拡張文字セットをインストール
-DENABLED_LOCAL_INFILE=1//ローカルからのデータのインポートを許可
cmakeコマンドを実行します.
makeコマンドを実行します.
make installコマンドを実行します.
(5)ディレクトリ権限の設定
上記コマンドは、データディレクトリdataの所属ユーザと所属ユーザグループをmysqlに設定し、mysqlディレクトリの下の他のファイルの所属ユーザをrootに設定し、所属グループをmysqlに設定します.
(6)mysqlプロファイルの設定
(7)システムデータベースを作成するテーブル
(8)環境変数の設定
(9)mysqlサーバの起動
サービスコマンドを使用してmysqlを起動するにはmysqlをスクリプトsupport-files/mysqlを起動する必要があります.サーバを/etc/initに追加します.dディレクトリの下で、以下の設定を行います.
(10)rootアカウントにリモート接続を追加する能力
(11)ネイティブ匿名接続の空パスワードアカウントの削除

To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system
PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:
./bin/mysqladmin -u root password 'new-password'
./bin/mysqladmin -u root -h Betty password 'new-password'
Alternatively you can run:
./bin/mysql_secure_installation
which will also give you the option of removing the test
databases and anonymous user created by default. This is
strongly recommended for production servers.
See the manual for more instructions.
You can start the MySQL daemon with:
cd . ; ./bin/mysqld_safe &
You can test the MySQL daemon with mysql-test-run.pl
cd mysql-test ; perl mysql-test-run.pl
Please report any problems with the ./bin/mysqlbug script!
The latest information about MySQL is available on the web at
http://www.mysql.com
Support MySQL by buying support/licenses at http://shop.mysql.com
New default config file was created as ./my.cnf and
will be used by default by the server when you start it.
You may edit this file to change server settings
WARNING: Default config file /etc/my.cnf exists on the system
This file will be read by default by the MySQL server
If you do not want to use this, either remove it, or use the
--defaults-file argument to mysqld_safe when starting the server
