今天在Linux主機（CentOS 7）安裝（yum install方式）Mariadb（即開源MySQL）後，無法啟動mariadb，其實是安裝不完整，當然啟動不了，更不用說輸入
#mysql -u root
提示
Can’t connect to local MySQL server through socket ‘/tmp/mysql.sock’ (2)
安裝mariadb，先搜尋一發：
#yum search mariadb
出現：
#yum search mariadb Loaded plugins: langpacks ============================= N/S matched: mariadb ============================= mariadb-bench.x86_64 : MariaDB benchmark scripts and data mariadb-devel.i686 : Files for development of MariaDB/MySQL applications mariadb-devel.x86_64 : Files for development of MariaDB/MySQL applications mariadb-embedded.i686 : MariaDB as an embeddable library mariadb-embedded.x86_64 : MariaDB as an embeddable library mariadb-embedded-devel.i686 : Development files for MariaDB as an embeddable : library mariadb-embedded-devel.x86_64 : Development files for MariaDB as an embeddable : library mariadb-libs.i686 : The shared libraries required for MariaDB/MySQL clients mariadb-libs.x86_64 : The shared libraries required for MariaDB/MySQL clients mariadb-server.x86_64 : The MariaDB server and related files mariadb.x86_64 : A community developed branch of MySQL mariadb-test.x86_64 : The test suite distributed with MariaD
嗯，把 mariadb mariadb-bench mariadb-server mariadb-embdedeb mariadb-libs都安裝：
#yum install mariadb-embedded mariadb-libs mariadb-bench mariadb mariadb-server -y
先啟動（service命令就不要用了）
# systemctl start mariadb
開機啟動
$ systemctl enable mariadb
最後開啟安裝步驟
$ mysql_secure_installation
