CentOS系统编译安装MariaDB数据库实现多实例

[root@centos7 ~]#useradd -r -s /sbin/nologin mysql        
[root@centos7 ~]#id mysql           
uid=988(mysql) gid=983(mysql) groups=983(mysql)
[root@centos7 ~]#getent passwd mysql
mysql:x:988:983::/home/mysql:/sbin/nologin

[root@centos7 ~]#yum groupinstall "development tools" //安装包组
[root@centos7 ~]#yum install cmake //安装cmake
[root@centos7 ~]#tar xvf mariadb-10.2.12.tar.gz //解压
[root@centos7 ~]#mkdir /mysqldb //创建数据库文件
[root@centos7 ~]#chown mysql.mysql /mysqldb/ //数据库文件权限

[root@centos7 ~]#yum install  ncurses-devel
[root@centos7 ~]#yum install gnutls-devel
[root@centos7 ~]#yum install "libaio-devel"
[root@centos7 ~]#yum install "openssl-devel"
[root@centos7 ~]#yum install libxml2-devel
以上五个包是没有安装过，如果安装了请忽略！

[root@centos7 ~]#cd mariadb-10.2.12/
[root@centos7 mariadb-10.2.12]#cmake . -DCMAKE_INSTALL_PREFIX=/app/mysql -DMYSQL_DATADIR=/mysqldb/ -DSYSCONFDIR=/etc -DMYSQL_USER=mysql -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_ARCHIVE_STORAGE_ENGINE=1 -DWITH_BLACKHOLE_STORAGE_ENGINE=1 -DWITH_READLINE=1 -DWITH_SSL=system -DWITH_ZLIB=system -DWITH_LIBWRAP=0 -DMYSQL_UNIX_ADDR=/app/mysql/mysql.sock -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DENABLED_LOCAL_INFILE=1 -DWITH_PARTITION_STORAGE_ENGINE=1 -DWITH_DEBUG=0 -DWITHOUT_MROONGA_STORAGE_ENGINE=1

[root@centos7 mariadb-10.2.12]#make && make instal

path
[root@centos7 mysql]#echo 'PATH=/app/mysql/bin/:$PATH' >/etc/profile.d/mysql.sh
[root@centos7 mysql]#. /etc/profile.d/mysql.sh 

生成数据实例
[root@centos7 app]#/app//mysql/scripts/mysql_install_db --basedir=/app/mysql --datadir=/mysqldb/3306/data --user=mysql
[root@centos7 app]#ll /mysqldb/          
total 0
drwxr-xr-x 3 root root 18 Jan 23 21:36 3306

配置文件
cp /app/mysql/support-files/my-huge.cnf /etc/my.cnf
[root@centos7 app]#vim /etc/my.cnf
[mysqld]
datadir=/mysqldb/3306/data    //这里只需添加自己数据路径即可
port            = 3306

[root@centos7 app]#cp /app/mysql/support-files/mysql.server /etc/init.d/mysqld
[root@centos7 app]#vim  /etc/init.d/mysqld 

添加到启动服务
[root@centos7 app]#chkconfig --add mysqld
[root@centos7 app]#chkconfig --list
mysqld  0:off   1:off   2:on    3:on    4:on    5:on    6:off

[root@centos7 app]#ll /etc/init.d/
-rwxr-xr-x  1 root root 12184 Jan 23 21:43 mysqld
[root@centos7 app]#chown -R mysql.mysql /mysqldb/3306/
[root@centos7 app]#ll -d /mysqldb/3306/               
drwxr-xr-x 3 mysql mysql 18 Jan 23 21:36 /mysqldb/3306/


添加权限
[root@centos7 app]#chgrp -R mysql /app//mysql/
[root@centos7 app]#chmod 775 /app/mysql/

[root@centos7 ~]#service mysqld start //启动
Starting mysqld (via systemctl):                           [  OK  ]
[root@centos7 ~]#ss -ntl
LISTEN  0   80  :::3306 :::*  
这是3306端口已经启动 需要添加端口 多实例
[root@centos7 ~]#/app//mysql/scripts/mysql_install_db --basedir=/app/mysql --datadir=/mysqldb/3307/data --user=mysql
[root@centos7 ~]#/app//mysql/scripts/mysql_install_db --basedir=/app/mysql --datadir=/mysqldb/3308/data --user=mysql

以下操作3307、3308都需要做 只是端口数字需要改变以下
[root@centos7 ~]#vim /mysqldb/3307/my.cnf //修改和添加了这些
port            = 3307
[mysqld]
datadir=/mysqldb/3307/data
port            = 3307
socket          = /mysqldb/3307/mysql.sock
[mysql_safe]
log-error=/mysqldb/3307/mariadb.log
pid-file=/mysqldb/3307/mariadb.pid

[root@centos7 3307]#vim mysqld 
#!/bin/bash
port=3307  记得修改这个端口
mysql_user="root"
mysql_sock="${mysql_basedir}/${port}/mysql.sock" 这里也修改了一下

[root@centos7 3307]#./mysqld start 启动
