当前服务器已经安装了 MySQL ,现在为 Mariadb 的安装:

   # 解压文件   # tar zxvf mariadb-10.2.8-linux-x86_64.tar.gz   # mv mariadb-10.2.8-linux-x86_64 /usr/local/mariadb   # cd /usr/local/mariadb   # groupadd --system mariadb   # useradd -c "MariaDB Server" -d /usr/local/mariadb -g mariadb --system mariadb   # mkdir {logs,tmp,tokudb_data}   # chown -R mariadb:mariadb .         # 设置配置文件   # cp support-files/my-small.cnf ./my.cnf   # chown -R mariadb:mariadb my.cnf   # vim /etc/mariadb/my.cnf
   # vim /etc/mariadb/my.cnf      [client]   #password	= your_password   port		= 53307   socket		= /tmp/mariadb53307.sock      [mysql]   prompt = "MariaDB:\u@\h > "   default-character-set = 'utf8'   auto-rehash = FALSE   local-infile = 1   max-allowed-packet = 64M   secure-auth = TRUE      [mysqld]   user = mariadb   server-id	= 3153307   port		= 53307   socket		= /tmp/mariadb53307.sock   basedir		= /usr/local/mariadb   datadir         = /usr/local/mariadb/data   log-error	= /usr/local/mariadb/mariadb-err.log   tmpdir          = /usr/local/mariadb/tmp      log-bin = /usr/local/mariadb/logs/mariadb-bin   binlog-format = ROW   expire-logs-days = 15   max-binlog-size = 1024M   sync-binlog = 1   log-slave-updates      skip-name-resolve   lower_case_table_names = 1   event_scheduler = 1   character-set-server = 'utf8'   collation-server = 'utf8_general_ci'   default-storage-engine = 'InnoDB'   transaction-isolation = READ-COMMITTED   skip-external-locking   key_buffer_size = 64M   max_allowed_packet = 32M      innodb-flush-log-at-trx-commit = 1   innodb-buffer-pool-size = 2G   innodb-buffer-pool-instances = 2   innodb-file-per-table = 1      general_log_file = general.log   log-warnings = 2   log_error = error.log   slow-query-log = 1   slow_query_log_file = slow.log   long-query-time = 1   

 

   # 设置服务启动文件   # cp support-files/mysql.server /etc/init.d/mariadb   # chmod +x /etc/init.d/mariadb      # 修改服务器启动文件   # vim /etc/init.d/mariadb
   # 更改以下几处地方(前三处即可)   # vim /etc/init.d/mariadb         #1.指定 basedir 及 datadir 路径,添加配置文件变量 conf,修改3处   basedir=/usr/local/mariadb   datadir=/usr/local/mariadb/data   conf=$basedir/my.cnf         #2.在 start 启动服务处添加 “ --defaults-file="$conf" ”:   ……………………   $bindir/mysqld_safe --defaults-file="$conf" --datadir="$datadir" --pid-file="$mysqld_pid_file_path" "$@" &   ……………………         #3.在函数 wait_for_ready () 处添加 “ --defaults-file="$conf" ”:   ……………………   if $bindir/mysqladmin --defaults-file="$conf" ping >/dev/null 2>&1; then   ……………………         #4. "/usr/local/mysql" 替换为 "/usr/local/mariadb" :%s//usr/local/mysql//usr/local/mariadb/g
   # 初始化   # scripts/mysql_install_db --defaults-file=/usr/local/mariadb/my.cnf --user=mariadb         ------------------------------------------------------------------------------   Installing MariaDB/MySQL system tables in '/usr/local/mariadb/data' ...   OK      To start mysqld at boot time you have to copy   support-files/mysql.server to the right place for your system      PLEASE REMEMBER TO SET A PASSWORD FOR THE MariaDB root USER !   To do so, start the server, then issue the following commands:      './bin/mysqladmin' -u root password 'new-password'   './bin/mysqladmin' -u root -h 127.0.0.1   127.0.0.1 password 'new-password'      Alternatively you can run:   './bin/mysql_secure_installation'      which will also give you the option of removing the test   databases and anonymous user created by default.  This is   strongly recommended for production servers.      See the MariaDB Knowledgebase at http://mariadb.com/kb or the   MySQL manual for more instructions.      You can start the MariaDB daemon with:   cd '.' ; ./bin/mysqld_safe --datadir='/usr/local/mariadb/data'      You can test the MariaDB daemon with mysql-test-run.pl   cd './mysql-test' ; perl mysql-test-run.pl      Please report any problems at http://mariadb.org/jira      The latest information about MariaDB is available at http://mariadb.org/.   You can find additional information about the MySQL part at:   http://dev.mysql.com   Consider joining MariaDB's strong and vibrant community:   https://mariadb.org/get-involved/

 

   # 启动服务及设置开机启动   # /etc/init.d/mariadb start   # cd /etc/init.d   # chkconfig --add mariadb    # chkconfig --levels 3 mariadb on      # systemctl status mariadb.service            # 安装前面初始化的日志提示,首先设置root密码,如设置密码为 "mariadb"   # cd /usr/local/mariadb   # ./bin/mysqladmin -uroot -hlocalhost.localdomain -P53307 password 'mariadb'         # 登录 mariadb 实例   # mysql -uroot -hlocalhost.localdomain -P53307 -p
