CentOS6.5 上部署 MySQL5.7.17 二进制安装以及多实例配置

1、建用户、下载、解压

groupadd mysql
useradd -r -g mysql mysql
wget http://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.17-linux-glibc2.5-x86_64.tar.gz
tar xvf mysql-5.7.17-linux-glibc2.5-x86_64.tar.gz -C /usr/local/ 
ln -sv /usr/local/mysql-5.7.17-linux-glibc2.5-x86_64 /usr/local/mysql

2、输出环境变量、帮助

/etc/profile
export PATH=$PATH:/usr/local/mysql/bin
source /etc/profile
vim /etc/man.config
MANPATH /usr/local/mysql/man

3、创建数据目录、授权、初始化mysql mysql5.7.7及以上做了很多改变，5.7.7以前安装方法和以前差不多，初始化也保留了mysql_install_db，5.7.7以后则去掉了该脚本，使用了-initialize 或者 --initialize-insecure 参数作为初始化。

  mysql5.7.14版本初始化时候已经抛弃了defaults-file参数文件，所以在初始化时候指定配置文件会出错，同时必须保证datadir为空。

mkdir /data/mysql
chown mysql.mysql /data/mysql
[root@leo mysql]# mysqld --verbose --help |more 查看更多初始化参数
[root@leo mysql]# /usr/local/mysql/bin/mysqld --initialize-insecure --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql
2016-12-21T09:37:13.532770Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details).
2016-12-21T09:37:16.364569Z 0 [Warning] InnoDB: New log files created, LSN=45790
2016-12-21T09:37:16.881727Z 0 [Warning] InnoDB: Creating foreign key constraint system tables.
2016-12-21T09:37:17.115686Z 0 [Warning] No existing UUID has been found, so we assume that this is the first time that this server has been started. Generating a new UUID: 0fbca93f-c761-11e6-9409-000c299a8601.
2016-12-21T09:37:17.220886Z 0 [Warning] Gtid table is not ready to be used. Table 'mysql.gtid_executed' cannot be opened.
2016-12-21T09:37:17.284087Z 1 [Warning] root@localhost is created with an empty password ! Please consider switching off the --initialize-insecure option.

初始化成功了。这里说明下，初始化参数我使用了--initialize-insecure，这样不会设置初始化root密码，如果是 --initialize的话，会随机生成一个密码：

4、设置加密连接

[root@leo mysql]# /usr/local/mysql/bin/mysql_ssl_rsa_setup 
Generating a 2048 bit RSA private key
..........................................................+++
.......+++
writing new private key to 'ca-key.pem'
-----
Generating a 2048 bit RSA private key
...........+++
...........................................+++
writing new private key to 'server-key.pem'
-----
Generating a 2048 bit RSA private key
............................................+++
.............................................................+++
writing new private key to 'client-key.pem'
-----

5、复制配置文件和启动脚本

[root@leo mysql]# cp /usr/local/mysql/support-files/my-default.cnf /etc/my.cnf
[root@leo mysql]# cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld

6、配置如下

[root@leo mysql]# cat /etc/my.cnf 
# For advice on how to change settings please see
# http://dev.mysql.com/doc/refman/5.7/en/server-configuration-defaults.html
# *** DO NOT EDIT THIS FILE. It's a template which will be copied to the
# *** default location during install, and will be replaced if you
# *** upgrade to a newer version of MySQL.
[mysqld]
# Remove leading # and set to the amount of RAM for the most important data
# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
# innodb_buffer_pool_size = 128M
# Remove leading # to turn on a very important data integrity option: logging
# changes to the binary log between backups.
# log_bin
# These are commonly set, remove the # and set as required.
basedir=/usr/local/mysql
datadir=/data/mysql
port=3306
server_id=1
socket=/data/mysql/mysql.sock
symbolic-links=0
character_set_server=utf8
# Remove leading # to set options mainly useful for reporting servers.
# The server defaults are faster for transactions and fast SELECTs.
# Adjust sizes as needed, experiment to find the optimal values.
# join_buffer_size = 128M
# sort_buffer_size = 2M
# read_rnd_buffer_size = 2M 
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES 
[client]
socket=/data/mysql/mysql.sock

7、启动、并查看日志

[root@leo ~]# /etc/init.d/mysqld start
Starting MySQL.Logging to '/data/mysql/leo.err'.
.                             [确定]

8、登录测试

多实例配置部分

1、复制多实例启动脚本

[root@leo ~]# cp /usr/local/mysql/support-files/mysqld_multi.server /etc/init.d/mysqld_multi

2、初始化数据库目录并修改多实例配置文件

mkdir /data/mysql2
mkdir /data/mysql3
chown mysql.mysql /data/mysql2
chown mysql.mysql /data/mysql3
[root@leo ~]# /usr/local/mysql/bin/mysqld --initialize-insecure --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql2

3、启动多实例测试并查看日志

[root@leo ~]# /etc/init.d/mysqld_multi start
[root@leo ~]# /etc/init.d/mysqld_multi report
Reporting MySQL servers
MySQL server from group: mysqld1 is running
MySQL server from group: mysqld2 is running

[root@leo ~]# netstat -antlp |grep :330*

tcp    0   0 :::3306           :::*            LISTEN   55764/mysqld

4、连接测试

[root@leo ~]# mysql -uroot -h127.0.0.1 -P3308 -p

[root@leo ~]# mysqladmin -uroot -p -S /data/mysql3/mysql.sock shutdown #关闭实例

5、附带脚本多实例管理脚本

stop关闭MySQL实例，注意此处是需要一个具有shutdown权限的用户，且密码并被是加密的，也不可以交互式输入密码，Linux又具有history功能，所以为了数据库的安全，还是不要用mysqld_multi stop的方式关闭数据库了吧

[root@leo ~]# cat /etc/init.d/mysqld_multi
#!/bin/sh
#

# This script assumes that my.cnf file exists either in /etc/my.cnf or
# /root/.my.cnf and has groups [mysqld_multi] and [mysqldN]. See the
# mysqld_multi documentation for detailed instructions.

if test -x $bindir/mysqld_multi
then
 mysqld_multi="$bindir/mysqld_multi";
else
 echo "Can't execute $bindir/mysqld_multi from dir $basedir";
 exit;
fi
case "$1" in
  'start' )
    "$mysqld_multi" --defaults-extra-file=$conf start $2
    ;;
  'stop' )
    "$mysqld_multi" --defaults-extra-file=$conf stop $2 --user=root --password=redhat
    ;;
  'report' )
    "$mysqld_multi" --defaults-extra-file=$conf report $2
    ;;
  'restart' )
    "$mysqld_multi" --defaults-extra-file=$conf stop $2 --user=root --password=redhat
    "$mysqld_multi" --defaults-extra-file=$conf start $2
    ;;
  *)
    echo "Usage: $0 {start|stop|report|restart}" >&2
    ;;
esac

6、多实例测试启停

[root@leo ~]# /etc/init.d/mysqld_multi stop
[root@leo ~]# /etc/init.d/mysqld_multi report

mysqld_multi启动会查找my.cnf文件中的[mysqldN]组，N为mysqld_multi后携带的整数值。 mysqld_multi的固定选项可在配置文件my.cnf中进行配置，在[mysqld_multi]组下配置（如果没有该组，可自行建立）。 mysqld_multi使用方式如下： mysqld_multi [options] {start|stop|reload|report} [GNR[,GNR] ...]

以上所述是小编给大家介绍的CentOS6.5 上部署 MySQL5.7.17 二进制安装以及多实例配置，希望对大家有所帮助，如果大家有任何疑问请给我留言，小编会及时回复大家的。在此也非常感谢大家对网站的支持！
