sudo yum install postgresqlがCentOS 7で機能しませんか？

CentOS 7にPostgreSQLをインストールしようとしています（ このガイド に従ってDiscourseをインストールします）が、次のコマンドを入力すると、

Sudo yum install postgresql91-server.x86_64 postgresql91-contrib.x86_64 postgresql91-devel.x86_64

私はこのエラーを受け取ります：

Loaded plugins: fastestmirror base                                     | 3.6 kB  00:00:00 epel/x86_64/metalink                                |  24 kB  00:00:00 extras                                              | 3.4 kB  00:00:00 nginx                                               | 2.9 kB  00:00:00 http://yum.postgresql.org/9.1/redhat/rhel-7-x86_64/repodata/repomd.xml: [Errno 14] HTTP Error 404 - Not Found Trying other mirror. To address this issue please refer to the below knowledge base article

If above article doesn't help to resolve this issue please create a bug on https://bugs.centos.org/



 One of the configured repositories failed (PostgreSQL 9.1 7 - x86_64),  and yum doesn't have enough cached data to continue. At this point the only  safe thing yum can do is fail. There are a few ways to work "fix" this:

     1. Contact the upstream for the repository and get them to fix the problem.

     2. Reconfigure the baseurl/etc. for the repository, to point to a working
        upstream. This is most often useful if you are using a newer
        distribution release than is supported by the repository (and the
        packages for the previous distribution release still work).

     3. Disable the repository, so yum won't use it by default. Yum will then
        just ignore the repository until you permanently enable it again or use
        --enablerepo for temporary usage:

            yum-config-manager --disable pgdg91

     4. Configure the failing repository to be skipped, if it is unavailable.
        Note that yum will try to contact the repo. when it runs most commands,
        so will have to try and fail each time (and thus. yum will be be much
        slower). If it is a very temporary problem though, this is often a Nice
        compromise:

            yum-config-manager --save --setopt=pgdg91.skip_if_unavailable=true

failure: repodata/repomd.xml from pgdg91: [Errno 256] No more mirrors to try. http://yum.postgresql.org/9.1/redhat/rhel-7-x86_64/repodata/repomd.xml: [Errno 14] HTTP Error 404 - Not Found

この問題を解決する方法についてのヒントはありますか？

CentOS 7にPostgreSQL（64ビット）をインストールするには、次のコマンドを実行します。

wget https://download.postgresql.org/pub/repos/yum/9.6/redhat/rhel-7-x86_64/pgdg-centos96-9.6-1.noarch.rpm
rpm -Uvh http://yum.postgresql.org/9.6/redhat/rhel-7-x86_64/pgdg-centos96-9.6-1.noarch.rpm
yum update
yum -y install postgresql96-server postgresql96-devel postgresql96-contrib

Postgresqlデータベースを初期化します。

/usr/pgsql-9.6/bin/postgresql96-setup initdb

Postgresqlサービスを開始し、ブート時に有効にします。

systemctl enable postgresql-9.6
systemctl start postgresql-9.6

まず、このページ PostgreSQLリポジトリパッケージ から、インストールするPostgreSQLのバージョンを見つけ、リンクをコピーします。

次に、コピーしたリンクを使用してこのコマンドを実行します。

#Sudo yum install https://download.postgresql.org/pub/repos/yum/9.5/redhat/rhel-7-x86_64/pgdg-centos95-9.5-2.noarch.rpm

その後：

#Sudo yum install -y postgresql95-server.x86_64 postgresql95-contrib.x86_64 postgresql95-libs.x86_64
#/usr/pgsql-9.5/bin/postgresql95-setup initdb
#Sudo systemctl start postgresql-9.5.service

また、起動時にPostgreSQLを起動する場合：

#Sudo systemctl enable postgresql-9.5.service
