1、卸载系统自带的MySQL或mariadb及boost
[root@rhel7 ~]# rpm -qa | grep mysql
[root@rhel7 ~]# rpm -qa | grep mariadb
mariadb-libs-5.5.52-1.el7.x86_64
[root@rhel7 ~]# rpm -e --nodeps mariadb-libs-5.5.52-1.el7.x86_64
[root@rhel7 ~]# rpm -qa|grep boost
[root@rhel7 ~]#


2、查看是否存在mysql用户及组

[root@rhel7 ~]# cat /etc/group | grep mysql
[root@rhel7 ~]# cat /etc/passwd | grep mysql


3、创建mysql用户和组

[root@rhel7 ~]# groupadd mysql

[root@rhel7 ~]# useradd -g mysql -s /usr/sbin/nologin  mysql


4、创建mariadb安装目录

[root@rhel7 ~]#  mkdir -p /usr/local/mysql/data


5、安装编译软件

[root@rhel7 ~]# yum install make gcc-c++ cmake  libaio libaio-devel perl-Data-Dumper net-tools  ncurses-devel bison bison-devel gcc-c++ ncurses-devel cmake  perl gcc autoconf automake zlib libxml libgcrypt libtool openssl-devel -y


6、安装lrzsz，使用lrzsz上传mariadb-10.2.6.tar.gz

[root@rhel7 ~]#  yum install lrzsz

[root@rhel7 ~]#  rz

上传MySql压缩包


7、解压mariadb-10.2.6.tar.gz数据包

[root@rhel7 ~]#tar zxvf mariadb-10.2.6.tar.gz


8、cmake
[root@rhel7 ~]#cd mariadb-10.2.6
[root@rhel7 ~]#cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_DATADIR=/usr/local/mysql/data -DSYSCONFDIR=/etc -DWITHOUT_TOKUDB=1 -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_ARCHIVE_STPRAGE_ENGINE=1 -DWITH_BLACKHOLE_STORAGE_ENGINE=1 -DWIYH_READLINE=1 -DWIYH_SSL=system -DVITH_ZLIB=system -DWITH_LOBWRAP=0 -DMYSQL_UNIX_ADDR=/usr/local/mysql/data/mysql.sock -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci

9、make

make -j 6 \\指定几个线程处理


10、make install    \\安装到指定目录


11、更改mysql目录权限

[root@rhel7 ~]# chown -R mysql.mysql /usr/local/mysql/


12、把mysql的执行路径加入PATH中

[root@rhel7 ~]#  vi /etc/profile

export PATH=$PATH:/usr/local/mysql/bin            \\把此行加入到最后一行

[root@rhel7 ~]#  source /etc/profile


13、cp适合的配置文件
[root@rhel7 ~]# ls /usr/local/mysql/support-files/
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@rhel7 ~]#cp /usr/local/mysql/support-files/my-small.cnf   /etc/my.cnf


14、修改/etc/my.cnf
[root@rhel7 ~]# cat /etc/my.cnf
# Example MySQL config file for small systems.
#
# This is for a system with little memory (<= 64M) where MySQL is only used
# from time to time and it's important that the mysqld daemon
# doesn't use much resources.
#
# MySQL programs look for option files in a set of
# locations which depend on the deployment platform.
# You can copy this option file to one of those
# locations. For information about these locations, see:
# http://dev.mysql.com/doc/mysql/en/option-files.html
#
# 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
port            = 3306
socket          = /usr/local/mysql/data/mysql.sock

# Here follows entries for some specific programs

# The MySQL server
[mysqld]
basedir        = /usr/local/mysql               //增加
datadir        = /usr/local/mysql/data          //增加
port            = 3306
socket          = /usr/local/mysql/data/mysql.sock
skip-external-locking
key_buffer_size = 16K
max_allowed_packet = 1M
table_open_cache = 4
sort_buffer_size = 64K
read_buffer_size = 256K
read_rnd_buffer_size = 256K
net_buffer_length = 2K
thread_stack = 240K

# Don't listen on a TCP/IP port at all. This can be a security enhancement,
# if all processes that need to connect to mysqld run on the same host.
# All interaction with mysqld must be made via Unix sockets or named pipes.
# Note that using this option without enabling named pipes on Windows
# (using the "enable-named-pipe" option) will render mysqld useless!
#
#skip-networking
server-id       = 254

# Uncomment the following if you want to log updates
#log-bin=mysql-bin

# binary logging format - mixed recommended
#binlog_format=mixed

# Causes updates to non-transactional engines using statement format to be
# written directly to binary log. Before using this option make sure that
# there are no dependencies between transactional and non-transactional
# tables such as in the statement INSERT INTO t_myisam SELECT * FROM
# t_innodb; otherwise, slaves may diverge from the master.
#binlog_direct_non_transactional_updates=TRUE

# Uncomment the following if you are using InnoDB tables
#innodb_data_home_dir = /usr/local/mysql/data
#innodb_data_file_path = ibdata1:10M:autoextend
#innodb_log_group_home_dir = /usr/local/mysql/data
# You can set .._buffer_pool_size up to 50 - 80 %
# of RAM but beware of setting memory usage too high
#innodb_buffer_pool_size = 16M
#innodb_additional_mem_pool_size = 2M
# Set .._log_file_size to 25 % of buffer pool size
#innodb_log_file_size = 5M
#innodb_log_buffer_size = 8M
#innodb_flush_log_at_trx_commit = 1
#innodb_lock_wait_timeout = 50

[mysqldump]

#safe-updates

[myisamchk]
key_buffer_size = 8M
sort_buffer_size = 8M

[mysqlhotcopy]
interactive-timeout
[root@rhel7 ~]#

15、拷贝mysql服务
[root@rhel7 ~]# cp /usr/local/mysql/support-files/mysql.server  /etc/rc.d/init.d/mysqld


16、初始化数据库
[root@rhel7 scripts]# /usr/local/mysql/scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data/ --defaults-file=/etc/my.cnf


17、启动数据库
[root@rhel7 ~]# /etc/rc.d/init.d/mysqld start

18、查看端口是否正常
[root@rhel7 ~]# netstat -tunlp|grep 3306
tcp6       0      0 :::3306                 :::*                    LISTEN      1090/mysqld    


19、设置MariaDB root密码

[root@node1 system]# /usr/local/mysql/bin/mysqladmin -u root  password "root@123"

20、登陆MariaDB数据库
[root@rhel7 ~]# mysql -u root -p
Enter password:
Welcome to the MariaDB monitor.  Commands end with ; or \g.
Your MariaDB connection id is 10

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

MariaDB [(none)]>

21、修改密码

ALTER USER 'root'@'localhost' IDENTIFIED BY 'root@123';


22、远程登录权限

GRANT ALL PRIVILEGES ON *.* TO root@'%' IDENTIFIED BY 'root@123';

FLUSH PRIVILEGES;


23、配置mysql自启动
[root@rhel7 ~]# chkconfig --add mysqld
[root@rhel7 ~]# chkconfig mysqld on
[root@rhel7 ~]# chkconfig --list

Note: This output shows SysV services only and does not include native
      systemd services. SysV configuration data might be overridden by native
      systemd configuration.

      If you want to list systemd services use 'systemctl list-unit-files'.
      To see services enabled on particular target use
      'systemctl list-dependencies [target]'.

mysqld          0:off   1:off   2:on    3:on    4:on    5:on    6:off

24、为mysql开启防火墙

firewall-cmd --permanent --zone=public --add-port=3306/tcp
