二进制和源码安装mariadb-10.2.25，
实验：二进制安装mariadb-10.2.25
1）准备用户和家目录文件及权限
getent passwd mysql #查看有无mysql用户
groupadd -r -g 306 mysql #创建组id为306的mysql组
useradd -r -g 306 -u 306 -d /data/mysql mysql #创建mysql的用户指定家目录的路径
mkdir /data/mysql #创建数据库文件夹
chown 306:306 /data/mysql #修改权限
2）准备二进制程序
tar xvf mariadb-10.2.25-linux-x86_64.tar.gz -C /usr/local/
cd /usr/local/
ln -sv mariadb-10.2.25-linux-x86_64 mysql 创建软连接
chown -R root:root mysql/ 将mysql所有文件改成root权限
3） 创建数据库文件
cd /usr/local/mysql/
./scripts/mysql_install_db --datadir=/data/mysql --user=mysql
4）准备配置文件
mkdir /etc/mysql/
cp support-files/my-huge.cnf /etc/mysql/my.cnf 拷贝配置文件并命名为至/etc/mysql/my.cnf
vim /etc/mysql/my.cnf 修改数据库路径
5）准备服务脚本，并启动服务
cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
chkconfig --list 列出当前清单
chkconfig --add mysqld
service mysqld start
#如果有对应的service 文件可以执行下面
cp /usr/local/mysql/support-files/systemd/mariadb.service /usr/lib/systemd/system/ 复制服务脚本到服务目录中
systemctl daemon-reload
systemctl enable --now mariad
6）PATH路径
echo 'PATH=/usr/local/mysql/bin:$PATH' > /etc/profile.d/mysql.sh
. /etc/profile.d/mysql.sh
7）安全初始化
/usr/local/mysql/bin/mysql_secure_installation
实验：源码编译安装mariadb-10.2.25.tar.gz
1）安装相关依赖包
yum -y install gcc gcc-c++ cmake bison bison-devel zlib-devel libcurl-devel
libarchive-devel boost-devel ncurses-devel gnutls-devel libxml2-devel
openssl-devel libevent-devel libaio-devel perl-Data-Dumper
2）准备数据库目录和用户
groupadd -r -g 306 mysql
useradd -r -g 306 -u 306 -d /data/mysql mysql
getent passwd
mkdir /data/mysql
chown 306:306 /data/mysql
3）源码编译安装 MySQL
cd mysql-5.6.51/
cmake . \
-DCMAKE_INSTALL_PREFIX=/apps/mysql \
-DMYSQL_DATADIR=/data/mysql/ \
-DSYSCONFDIR=/etc/ \
-DMYSQL_USER=mysql \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DWITH_ARCHIVE_STORAGE_ENGINE=1 \
-DWITH_BLACKHOLE_STORAGE_ENGINE=1 \
-DWITH_PARTITION_STORAGE_ENGINE=1 \
-DWITHOUT_MROONGA_STORAGE_ENGINE=1 \
-DWITH_DEBUG=0 \
-DWITH_READLINE=1 \
-DWITH_SSL=system \
-DWITH_ZLIB=system \
-DWITH_LIBWRAP=0 \
-DENABLED_LOCAL_INFILE=1 \
-DMYSQL_UNIX_ADDR=/data/mysql/mysql.sock \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci
make -j 2&& make install #虚拟机只有2个cpu
后面的步骤和二进制一样，只是注意安装路径变为/apps/mysql/
并且不需要建立软链接
cd apps/mysql/
scripts/mysql_install_db --datadir=/data/mysql/ --user=mysql
cp /apps/mysql/support-files/my-huge.cnf /etc/mysql/my.cnf
sed -i '/\[mysqld\]/a\datadir=/data/mysql' /etc/mysql/my.cnf\
cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
chkconfig --add mysqld
\cp -f /usr/local/mysql/support-files/mysql.server /usr/lib/systemd/system/
systemctl daemon-reload
echo 'PATH=/usr/local/mysql/bin:$PATH' > /etc/profile.d/mysql.sh
. /etc/profile.d/mysql.sh
systemctl start mysql
