Centos7源碼安裝mariadb

1，下載並解壓安裝包到指定目錄

下載地址：https://downloads.mariadb.org/
可根據須要下載不一樣的軟件版本

tar xf  mariadb-5.5.31-linux-x86_64.tar.gz   -C /usr/local/

2，建立mysql組和用戶

groupadd -r -g 306 mysql
useradd -r -g 306 -u 306 –d /data/mysql mysql

3，進入到解壓目錄中，並設置目錄的全部者和所屬組

cd /usr/local
ln -sv mariadb-5.5.31-linux-x86_64 mysql
chown -R root:mysql /usr/local/mysql/

4，準備配置文件

mkdir /etc/mysql/ #設置配置文件的安裝位置
cp /usr/local/mysql/support-files/my-large.cnf /etc/mysql/my.cnf

5，修改配置文件

vim /etc/mysql/my.cnf
[mysqld]中添加三個選項：
datadir = /data/mysql #庫文件的所在位置，該文件夾的全部者和所屬組必須是mysql
innodb_file_per_table = on #數據庫中的表分開進行存放 
skip_name_resolve = on #禁止主機名解析，建議使用

6，建立數據庫文件

cd /usr/local/mysql/
./scripts/mysql_install_db --datadir=/data/mysql --user=mysql

若是出現以下錯誤：
./bin/mysqld: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory
則須要安裝
yum -y install  libaio

7，準備服務腳本，並啓動服務

cp ./support-files/mysql.server /etc/rc.d/init.d/mysqld
chkconfig --add mysqld
service mysqld start

8，設置PATH路徑

echo 'PATH=/usr/local/mysql/bin:$PATH' > /etc/profile.d/mysql

9，安全初始化

service mysqld restart #啓動mariadb服務
/user/local/mysql/bin/mysql_secure_installation
Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.

Set root password? [Y/n] y #是否設置root密碼
New password: 
Re-enter new password: 
Password updated successfully!
Reloading privilege tables..
 ... Success!

By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them.  This is intended only for testing, and to make the installation
go a bit smoother.  You should remove them before moving into a
production environment.

Remove anonymous users? [Y/n] y #是否移除匿名用戶
 ... Success!

Normally, root should only be allowed to connect from 'localhost'.  This
ensures that someone cannot guess at the root password from the network.

Disallow root login remotely? [Y/n] y #是否禁止root用戶遠程登陸
 ... Success!

By default, MariaDB comes with a database named 'test' that anyone can
access.  This is also intended only for testing, and should be removed
before moving into a production environment.

Remove test database and access to it? [Y/n] y #是否刪除test庫
 - Dropping test database...
 ... Success!
 - Removing privileges on test database...
 ... Success!

Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.

Reload privilege tables now? [Y/n] y #是否從新加載權限表，讓設置生效
 ... Success!

Cleaning up...

All done!  If you ave completed all of the above steps, your MariaDB
installation should now be secure.

Thanks for using MariaDB
