-------------------------------------------------------------------------------- /README.md: -------------------------------------------------------------------------------- 1 | # 基于MySQL 5.7多源复制+Keepalived搭建高可用 2 | 3 | ##说明 4 | 本内容来源于[知数堂](http://zhishuedu.com) 公开课 : 《MySQL 5.7 高可用新玩法》--吴炳锡 5 | 相关视频推荐：https://ke.qq.com/course/172600 6 | 7 | 8 | ##基本环境准备 9 | 使用Centos 6.X 64位系统 10 | MySQL 使用 MySQL-5.7.17-x86_64 版本，去官方下载mysql-5.7.17-linux-glibc2.5-x86_64.tar.gz 版本 11 | 12 | 13 | 14 | | 机器名 | 操作系统 | IP | 15 | | --- | --- | --- | 16 | | node1 | centos-6.8 | 192.168.11.100 | 17 | | node2 | centos-6.8 | 192.168.11.101 | 18 | | node3 | centos-6.8 | 192.168.11.102 | 19 | 20 | 对应的VIP： 192.168.11.110 21 | 22 | **特别提示:** 23 | 关闭iptables 24 | chkconfig --del iptables 25 | /etc/init.d/iptables stop 26 | 27 | 关闭:selinux 28 | setenforce 0 29 | vim /etc/sysconfig/selinux 30 | SELINUX=permissive 更改为： SELINUX=disabled 31 | 32 | ###下载MySQL ： 33 | 34 | ``` 35 | mkdir /data/Soft 36 | cd /data/Soft 37 | wget https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.17-linux-glibc2.5-x86_64.tar.gz 38 | ``` 39 | 40 | ###MySQL部署约定 41 | 二进制文件放置： /opt/mysql/ 下面对应的目录 42 | 数据文件全部放置到 /data/mysql/ 下面对应的目录 43 | 原始二进制文件下载到/data/Soft/ 44 | 45 | ##MySQL基本安装 46 | 以下安装步骤需要在node1, node2, node3上分别执行。 47 | 48 | 49 | 1. mkdir /opt/mysql 50 | 2. cd /opt/mysql 51 | 3. tar zxvf /data/Soft/mysql-5.7.17-linux-glibc2.5-x86_64.tar.gz 52 | 4. ln -s /opt/mysql/mysql-5.7.17-linux-glibc2.5-x86_64 /usr/local/mysql 53 | 5. mkdir /data/mysql/mysql3309/{data,logs,tmp} -p 54 | 6. groupadd mysql 55 | 7. useradd -g mysql -s /sbin/nologin -d /usr/local/mysql -M mysql 56 | 8. chown -R mysql:mysql /data/mysql/ 57 | 9. chown -R mysql:mysql /usr/local/mysql 58 | 10. cd /usr/local/mysql/ 59 | 11. ./bin/mysqld --defaults-file=/data/mysql/mysql3309/my3309.cnf --initialize 60 | 12. cat /data/mysql/mysql3309/data/error.log |grep password 61 | 13. /usr/local/mysql/bin/mysqld --defaults-file=/data/mysql/mysql3309/my3309.cnf & 62 | 14. echo "export PATH=$PATH:/usr/local/mysql/bin" >>/etc/profile 63 | 15. source /etc/profile 64 | 16. mysql -S /tmp/mysql3309.sock -p #输才查到密码进入MySQL 65 | 17. mysql>alter user user() identified by 'wubxwubx' 66 | 18. mysql>grant replication slave on *.* to 'repl'@'%' identified by 'repl4slave'; 67 | 19. mysql>grant all privilegs on *.* to 'wubx'@'%' identified by 'wubxwubx' # 一会测试使用的帐号 68 | 20. mysql>reset master 69 | 70 | 71 | 每个节点按上面进行,遇到初始化和启动故障请认真阅读/data/mysql/mysql3309/data/error.log 信息。 my3309.cnf 可以从相应的目录下载或是加入QQ群： 579036588 下载，有问题入裙讨论。 72 | 73 | ##搭建主从结构 74 | 75 | **node1上执行： ** 76 | 77 | 78 | mysql -S /tmp/mysql3309.sock -pwubxwubx 79 | 80 | mysql>change master to

115 | node1， node2， node3 上分别执行： 116 | **安装keepalived** 117 | ``` 118 | yum install keepalivled 119 | ``` 120 | **安装python依赖模块：** 121 | 122 | ``` 123 | yum install MySQL-python.x86_64 124 | yum install python2-filelock.noarch 125 | ``` 126 | 127 | ##keepalived配置 128 | 配置文件放置在： /etc/keepalived/keepalived.conf 129 | 内容如下： 130 | 131 | ``` 132 | vrrp_script vs_mysql_82 { 133 | script "/etc/keepalived/checkMySQL.py -h 127.0.0.1 -P 3309" 134 | interval 15 135 | } 136 | vrrp_instance VI_82 { 137 | state backup 138 | nopreempt 139 | interface eth1 140 | virtual_router_id 82 141 | priority 100 142 | advert_int 5 143 | authentication { 144 | auth_type PASS 145 | auth_pass 1111 146 | } 147 | track_script { 148 | vs_mysql_82 149 | } 150 | notify /etc/keepalived/notify.py 151 | virtual_ipaddress { 152 | 192.168.11.110 153 | } 154 | } 155 | ``` 156 | 157 | ##Keepalived启动 158 | node1, node2, node3分别执行： 159 | ``` 160 | /etc/init.d/keepalived start 161 | 162 | ``` 163 | 观查每个系统上的/var/log/messages 内容输出 164 | 165 | ##测试用例 166 | 在其它机器上使用： 167 | 168 | ``` 169 | mysql -h 192.168.11.110 -P 3309 -uwubx -pwubxwubx -e "select @@hostname" 170 | ``` 171 | 172 | 自已触发一下切换看看能不能完成自动化的切换。 173 | ## 关注知数堂公从号 第一时间参加技术交流 174 | ![知数堂公众号](https://github.com/zhishutech/mysqlha-keepalived-3node/blob/master/zst/zst-wxcode.jpg?raw=true) 175 | 176 |
