centOS6.6 源码安装mysql-5.7.19多实例

首先去官网下载mysql-5.7.19.tar.gz和mysql-boost-5.7.19.tar.gz

如图


将文件上传到linux服务器

说明：这里有两个源码包，自5.7版本之后就需要boost这个源码包，文章中所涉及的文件夹目录请根据自己的需要创建或修改

1.解压文件

[root@xin mysql]# tar  -zxf mysql-boost-5.7.19.tar.gz

[root@xin mysql]# tar  -zxf mysql-5.7.19.tar.gz

解压完成后当前目录下会出现 mysql-5.7-19文件夹

2.安装编译源码所需要的包和依赖

[root@xin mysql]# yum install -y cmake make gcc gcc-c++ ncurses-devel

3.安装完成之后执行编译命令

[root@xin mysql-5.7.19]# cmake -DCMAKE_INSTALL_PREFIX=/usr/mysql -DMYSQL_DATADIR=/usr/mysql/mysql_data/ -DDOWNLOAD_BOOST=1 -DWITH_BOOST=/usr/mysql/mysql-5.7.19/boost/boost_1_59_0

可根据需要，修改或新增参数

4.执行编译安装命令

[root@xin mysql-5.7.19]# make && make install

此命令执行时间较长，请耐心等待（若对mysql没有什么特殊的配置要求，可以选择二进制安装方式）

5.初始化数据库

创建my.cnf配置文件

[root@xin 3306]# vim my.cnf

[client]

添加mysql系统用户

[root@xin mysql-5.7.19]# useradd mysql–M -r -s /sbin/nologin 

添加操作文件权限
[root@xin mysql-5.7.19]# chmod 766 /usr/mysql/mysql_data/3306/mysql.err 

创建MySQL启动文件

[root@xin 3306]# vim mysql

#!/bin/sh  

port=3306  

mysql_user="root"  

mysql_pwd="weixin123456"  

cmd_path="/usr/mysql/bin"  

mysql_sock="/usr/mysql/mysql_data/${port}/mysql.sock"  

  

#startup function  

function_start_mysql()  

{  

    if [ ! -e "$mysql_sock" ];then  

      printf "Starting MySQL...\n"  

      /bin/sh ${cmd_path}/mysqld_safe --defaults-file=/usr/mysql/mysql_data/${port}/my.cnf 2>&1 > /dev/null &  

    else  

      printf "MySQL is running...\n"  

      exit  

    fi  

}  

#stop function  

function_stop_mysql()  

{  

    if [ ! -e "$mysql_sock" ];then  

       printf "MySQL is stopped...\n"  

       exit  

    else  

       printf "Stoping MySQL...\n"  

       ${cmd_path}/mysqladmin -u ${mysql_user} -p${mysql_pwd} -S /usr/mysql/mysql_data/${port}/mysql.sock shutdown  

   fi  

}  

#restart function  

function_restart_mysql()  

{  

    printf "Restarting MySQL...\n"  

    function_stop_mysql  

    sleep 2  

    function_start_mysql  

}  

case $1 in  

start)  

    function_start_mysql  

;;  

stop)  

    function_stop_mysql  

;;  

restart)  

    function_restart_mysql  

;;  

*)  

    printf "Usage: /usr/mysql/mysql_data/${port}/mysql {start|stop|restart}\n"  

esac  

添加操作文件权限

[root@xin 3306]# chmod 755 /usr/mysql/mysql_data/3306/mysql

添加文件夹的操作权限

[root@xin 3306]# chown –R mysql:mysql /usr/mysql

执行初始化命令，记录临时密码

[root@xin 3306]# /usr/mysql/bin/mysqld --initialize  --basedir=/usr/mysql --datadir=/usr/mysql/mysql_data/3306/data  --user=mysql

启动实例

[root@xin 3306]# /usr/mysql/mysql_data/3306/mysql start

查看是否已启动

[root@localhost ~]# netstat -lntp | grep mysql  

tcp        0      0 0.0.0.0:3307            0.0.0.0:*               LISTEN      4480/mysqld 

登陆实例

[root@localhost ~]#  cd  /usr/mysql  //切换到mysql的安装目录

[root@xin mysql]#  ./bin/mysql -u root -p -S ./mysql_data/3306/mysql.sock

Enter password:

重新设置密码

mysql> SET PASSWORD = PASSWORD('your_password');  

Query OK, 0 rows affected (0.03 sec) 

开启远程访问

mysql> grant all privileges on *.* to 'root'@'%' identified by 'weixin123456' with grant option;  
Query OK, 0 rows affected (0.03 sec) 

mysql> flush privileges;  

Query OK, 0 rows affected (0.03 sec)

开放防火墙端口

 [root@xin mysql]#  vi   /etc/sysconfig/iptables

编辑iptables文件，添加开放端口

-A INPUT -m state --state NEW -m tcp -p tcp --dport 3306 -j ACCEPT

重启防火墙

 [root@xin mysql]#  service iptables restart

至此端口为3306的mysql实例已经创建完了，若要创建3307、3308等，重复5步骤即可
