centos部署mysql CentOS6.5 上部署 MySQL5.7.17 二进制安装以及多实例配置
雁南飞丶 人气:01、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

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 2016-12-21T16:36:00.886650Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated.

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 MySQL server from group: mysqld3 is running [root@leo ~]# netstat -antlp |grep :330* tcp 0 0 :::3307 :::* LISTEN 55762/mysqld tcp 0 0 :::3308 :::* LISTEN 55765/mysqld tcp 0 0 :::3306 :::* LISTEN 55764/mysqld
4、连接测试
[root@leo ~]# mysql -uroot -h127.0.0.1 -P3308 -p Enter password: Welcome to the MySQL monitor. Commands end with ; or \g.

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 # # A simple startup script for mysqld_multi by Tim Smith and Jani Tolonen. # This script assumes that my.cnf file exists either in /etc/my.cnf or # /root/.my.cnf and has groups [mysqld_multi] and [mysqldN].

6、多实例测试启停
[root@leo ~]# /etc/init.d/mysqld_multi stop [root@leo ~]# /etc/init.d/mysqld_multi report Reporting MySQL servers MySQL server from group: mysqld1 is not running MySQL server from group: mysqld2 is not running MySQL server from group: mysqld3 is not running [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 MySQL server from group: mysqld3 is running [root@leo ~]# netstat -antlp |grep :330* #查看监听端口 tcp 0 0 :::3307 :::* LISTEN 74667/mysqld tcp 0 0 :::3308 :::* LISTEN 74666/mysqld tcp 0 0 :::3306 :::* LISTEN 74665/mysqld [root@leo ~]# mysql -uroot -predhat -P3307 -h127.0.0.1 #登录3307 测试 mysql: [Warning] Using a password on the command line interface can be insecure.

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] ...]
