環(huán)境：虛擬機中分配的3個虛擬機系統(tǒng)分別為centos71，centos71，centos7-manager。
設(shè)計如下centos71與centos72 分別作數(shù)據(jù)節(jié)點和sql節(jié)點。centos7-manager作為管理節(jié)點。
由于安裝時沒有選擇網(wǎng)絡(luò)，導(dǎo)致虛擬機無法上網(wǎng)。解決辦法：
vim /etc/sysconfig/network-scripts/ifcfg-ens33?
將文件中
ONBOOT=no ? ??
改為
ONBOOT=yes
之后刷新network.service,即可上網(wǎng)
$ service network start
Starting network (via systemctl):? ? ? ? ? ? ? ? ? ? ? ? ? [? OK? ]
使用yum安裝，yum會自動解決依賴問題。
使用rpm的方式時候，依賴問題需要自己解決（主要是缺少python-paramiko，python2-crypto。運氣不好也會遇到‘Command "/usr/bin/python -u -c "import setuptools, tokenize;__file__='/tmp/pip-build-wUzz6E/pycrypto/setup.py';f=getattr(tokenize, 'open', open)(__file__);code=f.read().replace('\r\n', '\n');f.close();exec(compile(code, __file__, 'exec'))" install --record /tmp/pip-RBAH0V-record/install-record.txt --single-version-externally-managed --compile" failed with error code 1 in /tmp/pip-build-wUzz6E/pycrypto/’這樣的錯誤）。
由于新裝的Centos7系統(tǒng)需要更新
sudo yum update?? 或是 sudo yum upgrade
更新完成之后，配置yum的mysql的源，在[mysql yum 源](https://dev.mysql.com/downloads/repo/yum/) 選擇與自己系統(tǒng)的合適的rpm文件。我下載的是Red Hat Enterprise Linux 7 / Oracle Linux 7.
$ sudo yum install mysql-cluster-community-server
...
No package mysql-cluster-community-server available.
這是因為mysql 源配置不成功造成的！
sudo rpm -Uhv mysql57-community-release-el7-11.noarch.rpm

查看mysql的源信息

以上的錯誤主要是因為未更新perl。根據(jù)[官網(wǎng)手冊](https://dev.mysql.com/doc/mysql-yum-repo-quick-guide/en/)給出的指導(dǎo)
el7中noarch.rpm無法下載。需要到[pkgs.org--perl](https://centos.pkgs.org/7/epel-x86_64/epel-release-7-11.noarch.rpm.html)下載配置epel-release-***.rpm即可。在下載el7
$ wget http://dl.fedoraproject.org/pub/epel/7/x86_64/Packages/e/epel-release-7-11.noarch.rpm
下載成功后
$ rpm -Uhv epel-release-7-11.noarch.rpm
對于
Error: Package: akonadi-mysql-1.9.2-4.el7.x86_64 (@anaconda) Requires: mariadb-server Removing: 1:mariadb-server-5.5.56-2.el7.x86_64 (@anaconda) mariadb-server = 1:5.5.56-2.el7 Obsoleted By: mysql-cluster-community-server-7.6.3-1.el7.x86_64 (mysql-cluster-7.6-community) Not found
解決辦法
$ sudo yum erase mysql
$ sudo yum install mysql-cluste-community-server?
即可正確安裝！
安裝管理節(jié)點
$ sudo? yum install mysql-cluster-community-management-server
安裝數(shù)據(jù)節(jié)點
sudo yum install mysql-cluster-community-data-node
總結(jié)：對于安裝mysql cluster 請參看[官方文檔](https://dev.mysql.com/doc/mysql-yum-repo-quick-guide/en/#repo-qg-yum-installing)
