mackerel – 今日という日は贈り物

メールサーバPostfixの設定～

メールを受信したくなったので、メールサーバを立ち上げちゃうことにしました。
設定は以下の通り

・設定のバックアップ

# cd /etc/postfix/
# cp -p main.cf main.cf.org

1 2	# cd /etc/postfix/ # cp -p main.cf main.cf.org

・設定の変更

# vi main.cf
mydomain=snowdrop.asia
myorigin=snowdrop.asia
inet_interface=all
mydestination=$myhostname, localhost, $mydomain, localhost, $mydomain, yosshi.$mydomain
mynetwork_style=subnet
mynetwork=127.0.0.0/8 157.7.155.197
relay_domain=$mydomain

# vi main.cf

mydomain=snowdrop.asia

myorigin=snowdrop.asia

inet_interface=all

mydestination=$myhostname, localhost, $mydomain, localhost, $mydomain, yosshi.$mydomain

mynetwork_style=subnet

mynetwork=127.0.0.0/8 157.7.155.197

relay_domain=$mydomain

その他はそのままでございます。

・起動～

# /etc/init.d/postfix start

1	# /etc/init.d/postfix start

・DNSの設定

# vi /etc/named/named.snowdrop.asia
2 ; serial
IN MX 10 mx.snowdrop.asia.
mx IN A 157.7.155.197

# /etc/init.d/named reload

# vi /etc/named/named.snowdrop.asia

2 ; serial

IN MX 10 mx.snowdrop.asia.

mx IN A 157.7.155.197

# /etc/init.d/named reload

これで、外からもメールが届くかな♪

・mackerel監視を導入

# curl -fsSL https://mackerel.io/assets/files/scripts/setup-yum.sh | sh
# sudo yum install -y mackerel-agent

1 2	# curl -fsSL https://mackerel.io/assets/files/scripts/setup-yum.sh \| sh # sudo yum install -y mackerel-agent

・Postfixからgoogleにメールが届かない件
