solus 系统 - 安装 mariadb

# 安装 mariadb（这个系统没有 mysql 库）

$ sudo eopkg it mariadb

$ sudo eopkg it mariadb-server

# 初始化数据文件地址

$ sudo mysql_install_db --user=mysql --basedir=/usr/ --ldata=/var/lib/mysql/
$ sudo chmod -R mysql:mysql /var/lib/mysql

# 初始化后， 控制台输出以下结果：

To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system

PLEASE REMEMBER TO SET A PASSWORD FOR THE MariaDB root USER !
To do so, start the server, then issue the following commands:

'/usr//bin/mysqladmin' -u root password 'new-password'
'/usr//bin/mysqladmin' -u root -h lg-pc password 'new-password'

Alternatively you can run:
'/usr//bin/mysql_secure_installation'

which will also give you the option of removing the test
databases and anonymous user created by default.  This is
strongly recommended for production servers.

See the MariaDB Knowledgebase at http://mariadb.com/kb or the
MySQL manual for more instructions.

You can start the MariaDB daemon with:
cd '/usr/' ; /usr/bin/mysqld_safe --datadir='/var/lib/mysql/'

You can test the MariaDB daemon with mysql-test-run.pl
cd '/usr//mysql-test' ; perl mysql-test-run.pl

# 如上所示，使用 mysqld_safe 启动 mysql-server （实际上官网提供了3种启动服务器的方法，通常建议下面使用这种方式）

# 注意，mysqld_safe 默认的 --datadir选项默认值为 /var/db/mysql，如果设定了其他的 data目录，则必要指定该目录参数

$ cd '/usr/' ; /usr//bin/mysqld_safe --datadir='/var/lib/mysql/' 

# 初始化用户设置（比如设置root密码等）

$ /usr//bin/mysql_secure_installation

# 开机自启

上面那些是普通人的做法，而本屌只需要用三行脚本

# 如果你使用了类似前面的脚本，需要先删除 datadir文件夹
# rm -rf  /var/db/mysql

# 安装 mariadb 与 mariadb-server

# eopkg it mariadb mariadb-server

# 启动服务项

$ systemctl enable mariadb@
$ systemctl restart mariadb
$ systemctl status mariadb
