Linux下Mariadb下载安装，linuxmariadb

Linux下Mariadb下载安装，linuxmariadb

1.查看系统是否已有Mariadb包
[root@localhost ~]# rpm -qa | grep mariadb

mariadb-server-5.5.52-1.el7.x86_64

mariadb-libs-5.5.52-1.el7.x86_64

2.删除已有安装包

rpm -e  --nodeps mariadb-server-5.5.52-1.el7.x86_64

rpm -e  --nodeps mariadb-libs-5.5.52-1.el7.x86_64

(使用yum remove mysql mysql-server mysql-libs compat-mysql51全部删除；)

3.查找下载地址

http://mirrors.aliyun.com/mariadb/yum/10.1.20/centos7-amd64/

4.建立安装脚本

编辑内容如下

vim /etc/yum.repos.d/MariaDB.repo

[mariadb]
name = MariaDB
baseurl = http://mirrors.aliyun.com/mariadb/yum/10.1/centos/7.3/x86_64/
gpgkey =  http://mirrors.aliyun.com/mariadb/yum/RPM-GPG-KEY-MariaDB
gpgcheck = 1

:wq

5.开始yum安装

yum -y install MariaDB-server MariaDB-client

6.安装完成启动Mariadb

systemctl start mariadb

7.设置开机启动

systemctl enable mariadb

8.配置Mariadb

mysql_secure_installation

根据提示设置密码

以下仅作参考

Enter current password for root (enter for none):<–初次运行直接回车

设置密码

Set root password? [Y/n] <– 是否设置root用户密码，输入y并回车或直接回车
New password: <– 设置root用户的密码
Re-enter new password: <– 再输入一次你设置的密码

其他配置

Remove anonymous users? [Y/n] <– 是否删除匿名用户，回车

Disallow root login remotely? [Y/n] <–是否禁止root远程登录,回车,

Remove test database and access to it? [Y/n] <– 是否删除test数据库，回车

Reload privilege tables now? [Y/n] <– 是否重新加载权限表，回车

初始化MariaDB完成，接下来测试登录

mysql -uroot -ppassword

9.修改配置文件

vim /etc/my.cnf

# Example MySQL config file for medium systems.
#
# This is for a system with little memory (32M - 64M) where MySQL plays
# an important part, or systems up to 128M where MySQL is used together with
# other programs (such as a web server)
#
# You can copy this file to
# /etc/my.cnf to set global options,
# mysql-data-dir/my.cnf to set server-specific options (in this
# installation this directory is /opt/lampp/var/mysql) or
# ~/.my.cnf to set user-specific options.
#
# In this file, you can use all long options that a program supports.
# If you want to know which options a program supports, run the program
# with the "--help" option.

# The following options will be passed to all MySQL clients
[client]
#password	= your_password

# Replication Master Server (default)
# binary logging is required for replication
# log-bin deactivated by default since XAMPP 1.4.11

# defaults to 1 if master-host is not set
# but will not function as a master if omitted
#server-id	= 1

# Replication Slave (comment out master section to use this)
#
# To configure this host as a replication slave, you can choose between
# two methods :
#
# 1) Use the CHANGE MASTER TO command (fully described in our manual) -
#    the syntax is:
#
#    CHANGE MASTER TO MASTER_HOST=<host>, MASTER_PORT=<port>,
#    MASTER_USER=<user>, MASTER_PASSWORD=<password> ;
#
#    where you replace <host>, <user>, <password> by quoted strings and
#    <port> by the master's port number (3306 by default).
#
#    Example:
#
#    CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306,
#    MASTER_USER='joe', MASTER_PASSWORD='secret';
#
# OR
#
# 2) Set the variables below. However, in case you choose this method, then
#    start replication for the first time (even unsuccessfully, for example
#    if you mistyped the password in master-password and the slave fails to
#    connect), the slave will create a master.info file, and any later
#    change in this file to the variables' values below will be ignored and
#    overridden by the content of the master.info file, unless you shutdown
#    the slave server, delete master.info and restart the slaver server.
#    For that reason, you may want to leave the lines below untouched
#    (commented) and instead use CHANGE MASTER TO (see above)
#
# required unique id between 2 and 2^32 - 1
# (and different from the master)
# defaults to 2 if master-host is set
# but will not function as a slave if omitted
#server-id       = 2
#
# The replication master for this slave - required
#master-host     =   <hostname>
#
# The username the slave will use for authentication when connecting
# to the master - required
#master-user     =   <username>
#
# The password the slave will authenticate with when connecting to
# the master - required
#master-password =   <password>
#
# The port the master is listening on.
# optional - defaults to 3306
#master-port     =  <port>
#
# binary logging - not required for slaves, but recommended
#log-bin=mysql-bin

10.重启Mariadb

systemctl restart mysqld

11.如果启动失败

vim /etc/selinux/config 

改成如图所示

 

mysql -uroot -p

结束。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。
