Chefのレシピでmysql_secure_installation(bashリソース利用)

Last updated at Posted at 2013-08-22

この記事は最終更新から1年以上経過しています。 気をつけてね。

まずmysql_secure_installationするじゃないですか。もののついでにChefでやっておこうと思いました。

mysql_secure_installation実行時の質問を抜粋。

  1. Change the root password [Y/n]
  2. Remove anonymous users? [Y/n]
  3. Disallow root login remotely? [Y/n]
  4. Remove test database and access to it? [Y/n]
  5. Reload privilege tables now? [Y/n]

で、同様のことを実施。

mysql_secure_install.rb
bash 'mysql_secure_install emulate' do
  code <<-"EOH"
    /usr/bin/mysqladmin drop test -f
    /usr/bin/mysql -e "delete from user where user = '';" -D mysql
    /usr/bin/mysql -e "delete from user where user = 'root' and host = \'#{node[:hostname]}\';" -D mysql
    /usr/bin/mysql -e "SET PASSWORD FOR 'root'@'::1' = PASSWORD('newpassword');" -D mysql
    /usr/bin/mysql -e "SET PASSWORD FOR 'root'@'127.0.0.1' = PASSWORD('newpassword');" -D mysql
    /usr/bin/mysql -e "SET PASSWORD FOR 'root'@'localhost' = PASSWORD('newpassword');" -D mysql
    /usr/bin/mysqladmin flush-privileges -pnewpassword
  EOH
  action :run
  only_if "/usr/bin/mysql -u root -e 'show databases;'"
end

パスワードはencrypted_data_bagに置くとして、フルbashじゃないですか。

追記: 3. Disallow root login remotely? [Y/n] に当たる処理はコメント欄にある方が適切です。

result

試してみます、パスワード無しでmysqlに接続できるようならmysql_secure_installation相当の処理をさせます。

chef-apply
# cat <<'EOL' | chef-apply -s
> bash 'mysql_secure_install emulate' do
>   code <<-"EOH"
>     /usr/bin/mysqladmin drop test -f
>     /usr/bin/mysql -e "delete from user where user = '';" -D mysql
>     /usr/bin/mysql -e "delete from user where user = 'root' and host = \'#{node[:hostname]}\';" -D mysql
>     /usr/bin/mysql -e "SET PASSWORD FOR 'root'@'::1' = PASSWORD('newpassword');" -D mysql
>     /usr/bin/mysql -e "SET PASSWORD FOR 'root'@'127.0.0.1' = PASSWORD('newpassword');" -D mysql
>     /usr/bin/mysql -e "SET PASSWORD FOR 'root'@'localhost' = PASSWORD('newpassword');" -D mysql
>     /usr/bin/mysqladmin flush-privileges -pnewpassword
>   EOH
>   action :run
>   only_if "/usr/bin/mysql -u root -e 'show databases;'"
> end
> EOL

mysql_user_table
# mysql -e 'select user,host,password from user;' -D mysql -pnewpassword

| user | host      | password                                  |

| root | localhost | *FE4F2D624C07AAEBB979DA5C980D0250C37D8F63 |

まあできてるか。

2度目以降はonly_ifが効いてお断りしてくれます。

Recipe: (chef-apply cookbook)::(chef-apply recipe)
  * bash[mysql_secure_install emulate] action run (skipped due to only_if)
