本文详细介绍了在CentOS 6.9和7环境下通过二进制方式安装MariaDB的过程，包括系统准备、用户配置、解压安装包、配置文件设定、数据库文件创建、服务脚本准备及启动、日志文件准备、环境变量设置、安全初始化等步骤。

（1）查看系统中是否存在mysql

[root@centos7 ~]# rpm -qa mariadb*

[root@centos7 ~]#

注意：存在则删除 yum remove mysql

（2）准备用户

getent passwd mysql

useradd –d /app/mysqldb -r -m -s /sbin/nologin mysql （-d 指定用户的家目录 -r 创建系统用户 -s 指定用户的shell类型）

（3）解压之准备二进制程序

tar xvf mariadb-10.2.8-linux-x86_64.tar.gz -C /usr/local/ -C解压到指定目录下

Cd /usr/local/

ln -s mariadb-10.2.8-linux-x86_64/ mysql 创建软连接

（4）准备配置文件

配置文件格式：类ini格式，各程序由单个配置文件提供配[prog_name]

配置文件查找次序：后面覆盖前面的配置文件

/etc/my.cnf--> /etc/mysql/my.cnf--> --default-extra-file=/PATH/TO/CONF_FILE --> ~/.my.cnf

[root@centos7 local]# cd mysql/

[root@centos7 mysql]# ls

bin EXCEPTIONS-CLIENT mysql-test sql-bench

COPYING include README.md support-files

COPYING.thirdparty INSTALL-BINARY README-wsrep

CREDITS lib scripts

data man share

[root@centos7 mysql]# cp support-files/m

magic my-large.cnf mysqld_multi.server

my-huge.cnf my-medium.cnf mysql-log-rotate

my-innodb-heavy-4G.cnf my-small.cnf mysql.server

[root@centos7 mysql]# mkdir /etc/mysql/

[root@centos7 mysql]# cp support-files/my-huge.cnf /etc/mysql/my.cnf 

vim /etc/mysql/my.cnf

[mysqld]中添加三个选项：

datadir = /app/mysqldb

innodb_file_per_table = on

skip_name_resolve = on 禁止主机名解析

（5) 创建数据库文件

cd /usr/local/mysql/

scripts/mysql_install_db --user=mysql --datadir=/app/mysqldb

(6)准备服务脚本，并启动服务

cp support-files/mysql.server /etc/init.d/mysqld

chkconfig --list mysqld

chkconfig --add mysqld 添加

service mysqld start 失败

（7）准备日志文件

mkdir /var/log/mariadb/

chown mysql /var/log/mariadb/

service mysqld start

（8）设置环境变量

 vim /etc/profile.d/mysql.sh

PATH=/usr/local/mysql/bin:$PATH

. /etc/profile.d/mysql.sh

（9）安全初始化

mysql_secure_installation lsls

（10）静默模式登陆

 mysq l - uroot - p

注意：在centos 6.9二进制安装mariadb 5.5.57时，只在创建日志文件有所不同。

touch /var/log/mysqld.log

实验：用脚本实现上述两个实验
