Deploy MySQL Multi-instance

1. Compile and install CMake

# tar zxf cmake-3.5.2.tar.gz#./configure# Gmake # Gmake Install

3. Compile and install MySQL

#useradd mysql-s/sbin/nologin-m # yum install ncurses-devel-y# yum install libaio-devel-y# tar xvf mysql-5.5.49.tar.g z# CD mysql-5.5.49

4. Create a multi-instance data Catalog

Take two instances as an example

# mkdir-p/data/{3306,3307}/data# tree/data//data/|--3306| '--data '--3307 '--data

5. Set the first instance configuration file

# vi /data/3306/my.cnf[client]port = 3306socket = /data/3306/mysql.sock[mysql] no-auto-rehash[mysqld]user = mysqlport = 3306socket = /data/3306/ mysql.sockbasedir = /usr/local/mysqldatadir = /data/3306/dataopen_files_limit =  1024back_log = 600max_connections = 800max_connect_errors = 3000table_cache  = 614external-locking = FALSEmax_allowed_packet =8Msort_buffer_size =  1mjoin_buffer_size = 1mthread_cache_size = 100thread_concurrency = 2query_cache_ size = 2mquery_cache_limit = 1mquery_cache_min_res_unit = 2kthread_stack =  192ktmp_table_size = 2mmax_heap_table_size = 2mlong_query_time = 1pid-file  = /data/3306/mysql.pidlog-bin = /data/3306/mysql-binrelay-log = /data/3306/ relay-binrelay-log-info-file = /data/3306/relay-log.infobinlog_cache_size = 1mmax_binlog_cache_size = 1mmax_binlog_size  = 2Mexpire_logs_days = 7key_buffer_size = 16Mread_buffer_size =  1mread_rnd_buffer_size = 1mbulk_insert_buffer_size = 1mlower_case_table_names =  1skip-name-resolveslave-skip-errors = 1032,1062replicate-ignore-db=mysqlserver-id =  1innodb_additional_mem_pool_size = 4minnodb_buffer_pool_size = 32minnodb_data_file_path  = ibdata1:128M:autoextendinnodb_file_io_threads = 4innodb_thread_concurrency =  8innodb_flush_log_at_trx_commit = 2innodb_log_buffer_size = 2minnodb_log_file_size =  4minnodb_log_files_in_group = 3innodb_max_dirty_pages_pct = 90innodb_lock_wait_ timeout = 120innodb_file_per_table = 0[mysqldump]quickmax_allowed_packet = 2m[ mysqld_safe]log-error=/data/3306/mYsql_3306.errpid-file=/data/3306/mysqld.pid 

6. Set the startup text

vi /data/3306/mysqld#!/bin/shport=3306mysql_user= "root" mysql_pwd= "cmdpath="/application/usr/local/mysql/ Bin "mysql_sock="/data/${port}/mysql.sock "#startup  functionfunction_start_mysql () {  if [  ! -e  "$mysql _sock"  ];then    printf  "starting mysql...\n"     /bin/sh ${cmdpath}/mysqld_safe --defaults-file=/data/${port}/my.cnf 2 >&1 > /dev/null &  else    printf  "mysql  is running...\n "    exit  fi} #stop  functionfunction_stop_mysql () {   if [ ! -e  "$mysql _sock"  ];then     printf  " mysql is stopped...\n "     exit  else      printf  "stoping mysql...\n"      ${cmdpath}/mysqladmin -u ${ Mysql_user} -p${mysql_PWD} -S /DATA/${PORT}/MYSQL.SOCK SHUTDOWN   FI} #restart  functionfunction_ Restart_mysql () {  printf  "restarting mysql...\n"   function_stop_mysql   sleep 2  function_start_mysql}case $1 instart)   function_start_mysql;; Stop)   function_stop_mysql;; Restart)   function_restart_mysql;; *)   printf  "usage: /data/${port}/mysql {start|stop|restart}\n" esac# chown - R mysql.mysql /data/# chmod +x mysqld

7. Initializing the database

#/usr/local/mysql/scripts/mysql_install_db--basedir=/usr/local/mysql/--datadir=/data/3306/data/--user=mysql

8. Start the database

#/data/3306/mysqld Start

9. Log in to the database

# mysql-s/data/3306/mysql.sock

10. Configure a second instance

# cp/data/3306/my.cnf/data/3307/my.cnf# Cp/data/3306/mysqld/data/3307/mysqld//server-id changed to 2server-id = Sed-i ' s#33 06#3307#g '/data/3307/my.cnf# sed-i ' s#3306#3307#g '/data/3307/mysqld# chown-r mysql.mysql/data/#/usr/local/mysql/ scripts/mysql_install_db--basedir=/usr/local/mysql/--datadir=/data/3307/data/--user=mysql#/data/3307/mysqld start# mysql-s/data/3307/mysql.sock
