CentOS 7服務器上使用Nginx+phpMyAdmin

1，在CentOS7安裝epel源,(原服務器上要有php環境以及php的進程管理器php-fpm)
yum -y install epel-release

2，安裝phpMyAdmin軟件
yum -y install phpmyadmin

3，爲了使Nginx Web服務器正確地查找和提供phpMyAdmin文件，咱們只須要建立一個從安裝文件到咱們的Nginx文檔根目錄的符號連接：
ln -s /usr/share/phpMyAdmin /usr/share/nginx/html

4，配置nginx，以下圖

5，從新啓動咱們的PHP處理器，以確保它能夠加載咱們安裝的額外的PHP模塊：
systemctl restart php-fpm

6，這樣，咱們的phpMyAdmin安裝如今能夠運行。 要訪問該界面中，轉至服務器的域名或公網IP地址，後跟/phpMyAdmin ，在網頁瀏覽器
http://server_domain_or_IP/phpMyAdmin

7，咱們能夠受權咱們的mysql數據庫服務器對外遠程訪問
登陸mysql數據庫
msyql -uyourusername -pyoupassword
mysql > grant all privileges on . to yourMysqlUser@'%' identified by 'your password';
mysql > flush privileges;
mysql > exit;

8，測試並驗證

9，如果有多個須要鏈接的數據庫，能夠修改phpMyAdmin的配置文件，修改根目錄/etc/phpMyAdmin中的config.inc.php配置
$i = 0;

  $i++;

  $cfg['Servers'][$i]['auth_type'] = 'config';

  $cfg['Servers'][$i]['port'] = '3306';

  $cfg['Servers'][$i]['bs_temp_blob_timeout'] = 600;
  $cfg['Servers'][$i]['bs_temp_log_threshold'] = '32M';
  保存，打開phpmyadmin,在首頁就能夠看到服務器列表了
