1、首先查询下是否安装了mysql或者旧版本mariadb
rpm -qa | grep mysql
删除rm -rf /etc/my.cnf
2、安装依赖包
# yum install -y libevent
# yum groupinstall -y Development Tools
# yum install -y ncurses-devel openssl-devel openssl
3、创建数据库用户及组
#groupadd mysql
#useradd mysql -s /sbin/nologin -g mysql -M mysql
4、创建数据库数据存放目录及赋予权限
#mkdir /appliction/mydata -p
#chown mysql.mysql /appliction/mydata -R
一、编译安装开始
1、解压
#cmake . -DCMAKE_INSTALL_PREFIX=/appliction/mysql \ //安装目录
-DMYSQL_DATADIR=/appliction/mydata \ //数据库存放目录
-DWITH_INNOBASE_STORAGE_ENGINE=1 \ //支持数据库innobase引擎
-DWITH_ARCHIVE_STORAGE_ENGINE=1 \ //支持数据库archive引擎
-DWITH_BLACKHOLE_STORAGE_ENGINE=1 \ //支持数据库blackhole存储引擎
-DWITH_READLINE=1 \
-DWITH_SSL=system \
-DWITH_ZLIB=system \
-DWITH_LIBWRAP=0 \
-DMYSQL_UNIX_ADDR=/tmp/mysql.sock \
-DDEFAULT_CHARSET=utf8 \ //字符集utf8
-DDEFAULT_COLLATION=utf8_general_ci \ //校验字符
-DENABLED_LOCAL_INFILE=1 //允许本地导入数据
#make -j4
#make install
2、配置MariaDB
#cd /appliction/mysql
#scripts/mysql_install_db --user=mysql --datadir=/appliction/mydata
#ls /appliction/mydata (此目录原是空目录)
total 110616
16 -rw-rw----. 1 mysql mysql 16384 Mar 27 16:17 aria_log.00000001

49152 -rw-rw----. 1 mysql mysql 50331648 Mar 27 16:17 ib_logfile0
49152 -rw-rw----. 1 mysql mysql 50331648 Mar 27 16:17 ib_logfile1
4 drwx------. 2 mysql root 4096 Mar 27 16:17 mysql
0 drwx------. 2 mysql mysql 20 Mar 27 16:17 performance_schema
0 drwx------. 2 mysql root 6 Mar 27 16:17 test
3、删除my.cnf
# rm -rf /etc/my.cnf
# rm -rf /etc/my.cnf.d
4、复制配置文档
#cd /appliction/mysql/support-files/
#cp my-large.cnf /etc/my.cnf
4、创建启动脚本
# cd /appliction/mysql/support-files/
# cp mysql.server /etc/rc.d/init.d/mysqld
5、配置环境变量,方便直接输入mysql
# cat /etc/profile.d/mysql.sh
MYSQL_HOME=/appliction/mysql
export PATH=$MYSQL_HOME/bin:$PATH
#source /etc/profile.d/mysql.sh
6、启动数据库
# /etc/rc.d/init.d/mysqld start
Reloading systemd: [ OK ]
Starting mysqld (via systemctl): [ OK ]
7、登陆数据库,不需要密码
# mysql
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 4
Server version: 10.1.22-MariaDB Source distribution
Copyright (c) 2000, 2016, Oracle, MariaDB Corporation Ab and others.
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
MariaDB [(none)]>
8、初始化数据库,此方式可以禁用空密码登陆，按照提示输入你需要的Y或者N
# mysql_secure_installation
NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!
In order to log into MariaDB to secure it, we'll need the current
password for the root user. If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.
#输入当前root账号数据库密码,现在为空
Enter current password for root (enter for none):
OK, successfully used password, moving on...
Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.
#设置root密码
Set root password? [Y/n] y
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.
#是否移除匿名用户
Remove anonymous users? [Y/n] y
Normally, root should only be allowed to connect from 'localhost'. This
ensures that someone cannot guess at the root password from the network.
#是否禁止root用户远程登陆
Disallow root login remotely? [Y/n] y
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.
#是否移除test数据库
Remove test database and access to it? [Y/n] y
- Dropping test database...
- Removing privileges on test database...
Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.
#是否现在重新加载授权信息
Reload privilege tables now? [Y/n] Y
Cleaning up...
All done! If you've completed all of the above steps, your MariaDB
installation should now be secure.
Thanks for using MariaDB!
9、设置mysql本地方式免密码登陆
# egrep -v "^$|#" /etc/my.cnf （增加了红色部分）
[client]
port= 3306
socket= /tmp/mysql.sock
[mysqld]
skip-external-locking
key_buffer_size = 256M
max_allowed_packet = 1M
table_open_cache = 256
sort_buffer_size = 1M
read_buffer_size = 1M
read_rnd_buffer_size = 4M
myisam_sort_buffer_size = 64M
thread_cache_size = 8
query_cache_size= 16M
thread_concurrency = 8
log-bin=mysql-bin
binlog_format=mixed
server-id= 1
[mysqldump]
quick
max_allowed_packet = 16M
[mysql]
no-auto-rehash
user = root
password = 123456
host = 127.0.0.1
[myisamchk]
key_buffer_size = 128M
sort_buffer_size = 128M
read_buffer = 2M
write_buffer = 2M
[mysqlhotcopy]
interactive-timeout
注意事项：
若是重新安装需要make clean 及 rm CMAKECache.txt
