篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了MySQL5.6多实例安装相关的知识,希望对你有一定的参考价值。

Linux:centos 6.8 

mysql:5.6.23

一、安装多实例前准备

因为我的是新机器所以有好多软件没有,可能会导致之后编译出错

1.安装依赖包

[[email protected] ~]# yum install -y git gcc gcc-c++ ncurses-devel bison

2.mysql安装包

这里下载安装包时要注意了,不要选跟你的Linux系统不同的位数(64 and 32)。

二、安装mysql

1.解压安装包

[[email protected] ~]# tar xf mysql-5.6.23.tar.gz[[email protected] ~]# mv mysql-5.6.23 mysql                 ##改名[[email protected] ~]# mv mysql /usr/local/                  ##移动到指定位置

2.创建用户

[[email protected] ~]# useradd user                          ##创建用户[[email protected] ~]# chown -R mysql.mysql /data            ##更改属主属组

3.进行编译安装

[[email protected] ~]# cd /usr/local/mysql/
[[email protected] mysql]# cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql-5.6 \        ## MySQL安装路径
-DMYSQL_DATADIR=/usr/local/mysql-5.6/data \                                         ## MySQL数据存放路径-DMYSQL_UNIX_ADDR=/usr/local/mysql-5.6/tmp/mysql.sock \                             ## MySQL socke路径-DDEFAULT_CHARSET=utf8 \                                                            ## MySQL 字符集-DDEFAULT_COLLATION=utf8_general_ci \-DENABLED_LOCAL_INFILE=ON \-DWITH_INNOBASE_STORAGE_ENGINE=1 \-DWITH_FEDERATED_STORAGE_ENGINE=1 \-DWITH-BLACKHOLE_STORAGE_ENGINE=1 \-DWITHOUT_EXAMPLE_STORAGE_ENGINE=1 \-DWITHOUT_PARTITION_STORAGE_ENGING=1 \-DWITH_FAST_MUTEXES=1 \-DWITH_ZLIB=bundled \-DENABLED_LOCAL_INFIL=1 \-DWITH_READLINE=1 \-DWITH_EMBEDDED_SERVER=1 \[[email protected] mysql]# echo $?                          ##查看命令是否执行正确
0                                                       ##回复‘0’表示成功,回复非‘0’表示执行错误

[[email protected] mysql]# make && make install
[[email protected] mysql]# echo $?                          ##在不确定是要使用这个检查
0

4.创建MySQL多实例的数据文件目录(3306,3307)

[[email protected] mysql]# mkdir -p /data/{3306,3307}/data       ##因为是双实例[[email protected] mysql]# tree /data/data├── 3306            <- 3306实例的目录
│   └── data        <- 3306实例的数据文件目录├── 3307            <- 3307实例的目录
│   └── data        <- 3307实例的数据文件目录

5.创建数据库(3306,3307)配置文件

  • 3306 配置文件

6.配置MySQL命令 全局路径

[[email protected] ~]# echo "export PATH=/usr/local/mysql/bin:$PATH" >> /etc/profile[[email protected] ~]# source /etc/profile

7.初始化数据库

[[email protected] ~]# cd /usr/local/mysql/scripts/[[email protected] scripts]# ./mysql_install_db --basedir=/usr/local/mysql --datadir=/data/3306/data/ --user=mysql[[email protected] scripts]# echo $?0[[email protected] scripts]# ./mysql_install_db --basedir=/usr/local/mysql --datadir=/data/3307/data/ --user=mysql[[email protected] scripts]# echo $?0

8.多实例服务 启动和停止命令

启动命令

[[email protected] ~]# /usr/local/mysql/bin/mysqld_safe --defaults-file=/data/3306/my.cnf 2>&1 [[email protected] ~]# /usr/local/mysql/bin/mysqld_safe --defaults-file=/data/3307/my.cnf 2>&1 >

停止命令

[[email protected] ~]# /usr/local/mysql/bin/mysqladmin -uroot -p -S /data/3306/mysql.sock shutdown
[[email protected] ~]# /usr/local/mysql/bin/mysqladmin -uroot -p -S /data/3307/mysql.sock shutdown

查看服务启动状态

[[email protected] ~]# netstat -anpt|grep mysqltcp        0      0 :::3306                     :::*                        LISTEN      20886/mysqld        
tcp        0      0 :::3307                     :::*                        LISTEN      20045/mysqld

三、进入MySQL

1.进入MySQL(3306,3307)数据库

[[email protected] ~]# mysql -uroot -p -S /data/3306/mysql.sockmysql> show variables like ‘port‘;
+---------------+-------+| Variable_name | Value |
+---------------+-------+| port          | 3306  |
+---------------+-------+[[email protected] ~]# mysql -uroot -p -S /data/3307/mysql.sockmysql> show variables like ‘port‘;
+---------------+-------+| Variable_name | Value |
+---------------+-------+| port          | 3307  |
+---------------+-------+

2.更改root密码

mysql> update mysql.user set password=passwort(‘newpass‘) where user=‘root‘;
mysql> flush privileges

四、编写启动脚本

3306启动脚本

[[email protected] ~]# vim /data/3306/mysql#!/bin/bash# initport=3306mysql_user="root"mysql_pwd=""CmdPath="/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 $1 instart)    function_start_mysql
    ;;
restart)    function_restart_mysql
    ;;
stop)    function_stop_mysql
    ;;
*)    echo "/data/${port}/mysql {start|restart|stop}"
    ;;esac

3307启动脚本

#!/bin/bash# initport=3307mysql_user="root"mysql_pwd=""CmdPath="/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 $1 instart)    function_start_mysql
    ;;
restart)    function_restart_mysql
    ;;
stop)    function_stop_mysql
    ;;
*)    echo "/data/${port}/mysql {start|restart|stop}"
    ;;esac
