mysql多实例部署; 1.修改my.cnf [mysql] [mysqld_multi] mysqld = /usr/local/mysql/bin/mysqld_safe mysqladmin = /usr/local/mysql/bin/mysqladmin user = password = [mysqld1] #explicit_defaults_for_timestamp=true port = 3306 skip-name-resolve server_id=1 datadir=/data/master max_connections=3000 slow-query-log=on ##开启慢查询 slow-query-log-file=/var/log/mysql1/mysql-slow-queries.log long_query_time=3 ##开启二进制文件 log-bin=/data/master_binlog/mysql1_bin.log log-bin-index=/data/master_binlog/binlog.index binlog-do-db=ibuy innodb_buffer_pool_size=2G #缓存 innodb_log_file_size = 512M innodb_log_files_in_group = 3 innodb_additional_mem_pool_size = 64M socket=/var/lib/mysql/mysql3306.sock pid-file=/data/master/mysql.pid #query_cache_size = 128M #查询缓存，合适查操作比较多的数据库 symbolic-links=0 sql_mode=STRICT_TRANS_TABLES,NO_ENGINE_SUBSTITUTION log-error=/var/log/mysql1/mysqld.log user=mysql [mysqld2] port=3307 server_id=2 explicit_defaults_for_timestamp=true skip-name-resolve datadir=/data/slave max_connections=3000 slow-query-log=on ##开启慢查询 slow-query-log-file=/var/log/mysql2/mysql-slow-queries.log long_query_time=3 log-bin=/data/slave_binlog/mysql_bin.log ##开启二进制文件 log-bin-index=/data/slave_binlog/binlog.index binlog-do-db=ibuy innodb_buffer_pool_size=3G #缓存 innodb_log_file_size = 512M innodb_log_files_in_group = 3 innodb_additional_mem_pool_size = 64M socket=/var/lib/mysql/mysql3307.sock pid-file=/data/slave/mysql.pid #query_cache_size =512M #查询缓存，合适查操作比较多的数据库 symbolic-links=0 sql_mode=STRICT_TRANS_TABLES,NO_ENGINE_SUBSTITUTION log-error=/var/log/mysql2/mysqld.log user=mysql [mysqld_safe] #max_allowed_packet=20480 #log-error=/var/log/mysql/mysqld.log #pid-file=/var/run/mysqld/mysqld.pid 2.创建数据目录 mkdir -p /data/master mkdir -p /data/slave mkdir -p /data/master_binlog mkdir -p /data/slave_binlog mkdir /var/log/mysql1 mkdir /var/log/mysql2 chown mysql.mysql /data/master -R chown mysql.mysql /data/slave -R chmod 777 /var/log/mysql1 chmod 777 /var/log/mysql2 chmod 777 /var/lib/mysql 3.初始化DB /usr/local/mysql/scripts/mysql_install_db --datadir=/data/master /usr/local/mysql/scripts/mysql_install_db --datadir=/data/slave 4. 安装工具 cp /usr/local/mysql/bin/my_print_defaults /usr/bin/ 5.修改环境变量 #vim /etc/profile PATH=$PATH:/usr/local/mysql/bin export PATH 1.mysql启动 mysqld_multi start 1 启动实例1 mysqld_multi start 1-2 启动实例1,2 2.命令行登陆 mysql -u your_user -p your_password -P3307 -S /tmp/mysql3307.sock 由于涉及权限问题，mysqld_multi不能控制关闭mysql多实例，自己写了个关闭脚本 #!/bin/bash user="" password="" read -p "Please input mysqld ID 1-2:" ID if [ "$ID" == "1" ]; then #read -p "Please input mysqld port number 3306-3307:" port /usr/local/mysql/bin/mysqladmin -u$user -p$password -S /var/lib/mysql/mysql3306.sock shutdown && echo "close mysqld master successful" elif [ "$ID" == "2" ]; then /usr/local/mysql/bin/mysqladmin -u$user -p$password -S /var/lib/mysql/mysql3307.sock shutdown && echo "close mysqld slave successful" else echo "Please input mysqld ID 1-2:" fi （编辑：云计算网_宿迁站长网） 【声明】本站内容均来自网络，其相关言论仅代表作者个人观点，不代表本站立场。若无意侵犯到您的权利，请及时与联系站长删除相关内容! |
