This article is the download address of the built mariadb-10.0.17 version: https://downloads.mariadb.org/interstitial/mariadb-10.0.17/source/mariadb-10.0.17.tar.gz/from/http%3A//ftp.hosteurope.de/mirror/archive.mariadb.org/?serve
Master:192.168.1.166
Slave:192.168.1.165
1. Create an ordinary mysql account, set the directory where the database stores data, and set permissions
[root@zsxyweb3] # groupadd-r mysql
[root@zsxyweb3~] # useradd-r-g mysql-s / sbin/nologin mysql
[root@zsxyweb3~] # mkdir-p / data/mydata
[root@zsxyweb3~] # chown-R mysql:mysql / data
two。 Install the database dependency package
[root@zsxyweb3~] # yum install-y gcc gcc-c++ make cmake ncurses ncurses libxml2 libxml2-developenssl-devel bison bison-devel ncurses-devel
3. Upload mariadb package, decompress, compile and install.
[root@zsxyweb3 ~] # tar zxvf mariadb-10.0.17.tar.gz
[root@zsxyweb3 mariadb-10.0.17] # cmake-DCMAKE_INSTALL_PREFIX=/app/mysql-DMYSQL_DATADIR=/data/mydata-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=/tmp/mysql.sock-DDEFAULT_CHARSET=utf8-DDEFAULT_COLLATION=utf8_general_ci
[root@zsxyweb3 mariadb-10.0.17] # make&& make install
4. Copy the database startup script to the / etc/init.d/mysqld directory and modify the / etc/my.cnf configuration file.
[root@zsxyweb3mariadb-10.0.17] # cd / app/mysql/
[root@zsxyweb3mysql] # cp support-files/mysql.server / etc/rc.d/init.d/mysqld
[root@zsxyweb3mysql] # chmod + x / etc/rc.d/init.d/mysqld
[root@zsxyweb3mysql] # cp support-files/my-large.cnf / etc/my.cnf
5. Initialize the database, start the database
[root@zsxyweb3mysql] # scripts/mysql_install_db-user=mysql-datadir=/app/mysql/data
[root@zsxyweb3mysql] # mkdir log
[root@zsxyweb3mysql] # service mysqld start
6. System variables of the database
[root@zsxyweb3 mysql] # vim/etc/profile.d/mysqld.sh
Export PATH=$PATH:/usr/local/mysql/bin
[root@zsxyweb3 mysql] # source/etc/profile.d/mysqld.sh
[root@zsxyweb3 mysql] # mysql
