拓扑图
二、MySQL初始化安装过程
1、时间同步
[[email protected] ~]# ntpdate s2c.time.edu.cn [[email protected] ~]# ntpdate s2c.time.edu.cn 可根据需要在每个节点上定义crontab任务 [[email protected] ~]# which ntpdate /sbin/ntpdate [[email protected] ~]# echo "*/5 * * * * /sbin/ntpdate s2c.time.edu.cn &> /dev/null" >> /var/spool/cron/root [[email protected] ~]# crontab -l */5 * * * * /sbin/ntpdate s2c.time.edu.cn &> /dev/null
2、主机名称要与uname -n保持一致，并通过/etc/hosts解析
master [[email protected] ~]# hostname master.network.com [[email protected] ~]# uname -n master.network.com [[email protected] ~]# sed -i ‘[email protected]\(HOSTNAME=\).*@\[email protected]‘ /etc/sysconfig/network slave [[email protected] ~]# hostname slave.network.com [[email protected] ~]# uname -n slave.network.com [[email protected] ~]# sed -i ‘[email protected]\(HOSTNAME=\).*@\[email protected]‘ /etc/sysconfig/network master添加hosts解析 [[email protected] ~]# vim /etc/hosts [[email protected] ~]# cat /etc/hosts # Do not remove the following line, or various programs # that require network functionality will fail. 127.0.0.1 CentOS5.8 CentOS5 localhost.localdomain localhost ::1 localhost6.localdomain6 localhost6 172.16.1.101 master.network.com master 172.16.1.105 slave.network.com slave 拷贝此hosts文件至slave [[email protected] ~]# scp /etc/hosts slave:/etc/ [email protected]‘s password: hosts 100% 233 0.2KB/s 00:00
3、关闭iptables和selinux
master [[email protected] ~]# service iptables stop [[email protected] ~]# vim /etc/sysconfig/selinux [[email protected] ~]# cat /etc/sysconfig/selinux # This file controls the state of SELinux on the system. # SELINUX= can take one of these three values: # enforcing - SELinux security policy is enforced. # permissive - SELinux prints warnings instead of enforcing. # disabled - SELinux is fully disabled. #SELINUX=permissive SELINUX=disabled # SELINUXTYPE= type of policy in use. Possible values are: # targeted - Only targeted network daemons are protected. # strict - Full SELinux protection. SELINUXTYPE=targeted slave [[email protected] ~]# service iptables stop [[email protected] ~]# vim /etc/sysconfig/selinux [[email protected] ~]# cat /etc/sysconfig/selinux # This file controls the state of SELinux on the system. # SELINUX= can take one of these three values: # enforcing - SELinux security policy is enforced. # permissive - SELinux prints warnings instead of enforcing. # disabled - SELinux is fully disabled. #SELINUX=permissive SELINUX=disabled # SELINUXTYPE= type of policy in use. Possible values are: # targeted - Only targeted network daemons are protected. # strict - Full SELinux protection. SELINUXTYPE=targeted
4、Master安装并配置MySQL
数据目录底层最好是个逻辑卷，我这里就不再演示逻辑卷的创建了，我的博文中有，此处没有使用逻辑卷 准备数据目录并添加mysql用户 [[email protected] ~]# mkdir -pv /mydata/data mkdir: created directory `/mydata‘ mkdir: created directory `/mydata/data‘ [[email protected] ~]# groupadd -g 3306 mysql [[email protected] ~]# useradd -u 3306 -g mysql -M -s /sbin/nologin -d /mydata/data/ mysql [[email protected] ~]# chown -R mysql.mysql /mydata/data/ 解压并初始化mysql [[email protected] ~]# cd /tmp/ [[email protected] tmp]# tar xf mysql-5.6.26-linux-glibc2.5-x86_64.tar.gz -C /usr/local/ [[email protected] tmp]# cd /usr/local/ [[email protected] local]# ln -sv mysql-5.6.26-linux-glibc2.5-x86_64 mysql create symbolic link `mysql‘ to `mysql-5.6.26-linux-glibc2.5-x86_64‘ [[email protected] local]# cd mysql [[email protected] mysql]# chown -R root.mysql ./* [[email protected] mysql]# ll total 232 drwxr-xr-x 2 root mysql 4096 Jan 16 12:48 bin -rw-r--r-- 1 root mysql 17987 Jul 15 2015 COPYING drwxr-xr-x 3 root mysql 4096 Jan 16 12:49 data drwxr-xr-x 2 root mysql 4096 Jan 16 12:49 docs drwxr-xr-x 3 root mysql 4096 Jan 16 12:48 include -rw-r--r-- 1 root mysql 104897 Jul 15 2015 INSTALL-BINARY drwxr-xr-x 3 root mysql 4096 Jan 16 12:49 lib drwxr-xr-x 4 root mysql 4096 Jan 16 12:49 man drwxr-xr-x 10 root mysql 4096 Jan 16 12:49 mysql-test -rw-r--r-- 1 root mysql 2496 Jul 15 2015 README drwxr-xr-x 2 root mysql 4096 Jan 16 12:49 scripts drwxr-xr-x 28 root mysql 4096 Jan 16 12:49 share drwxr-xr-x 4 root mysql 4096 Jan 16 12:49 sql-bench drwxr-xr-x 2 root mysql 4096 Jan 16 12:49 support-files [[email protected] mysql]# scripts/mysql_install_db --user=mysql --datadir=/mydata/data/ Installing MySQL system tables...2016-01-16 12:57:52 0 [Warning] ‘THREAD_CONCURRENCY‘ is deprecated and will be removed in a future release. 2016-01-16 12:57:52 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated.

To do so, start the server, then issue the following commands: ./bin/mysqladmin -u root password ‘new-password‘ ./bin/mysqladmin -u root -h master.network.com password ‘new-password‘ Alternatively you can run: ./bin/mysql_secure_installation which will also give you the option of removing the test databases and anonymous user created by default. This is strongly recommended for production servers. See the manual for more instructions. You can start the MySQL daemon with: cd . ; ./bin/mysqld_safe & You can test the MySQL daemon with mysql-test-run.pl cd mysql-test ; perl mysql-test-run.pl Please report any problems at http://bugs.mysql.com/ The latest information about MySQL is available on the web at http://www.mysql.com Support MySQL by buying support/licenses at http://shop.mysql.com WARNING: Found existing config file ./my.cnf on the system.

三、基于GTID的主从模式配置过程
1、编辑master的配置文件
编辑配置文件，就在当前目录下(/usr/local/mysql) [[email protected] mysql]# vim my.cnf [mysqld] binlog-format=ROW log-bin=master-bin log-slave-updates=true gtid-mode=on enforce-gtid-consistency=true master-info-repository=TABLE relay-log-info-repository=TABLE sync-master-info=1 slave-parallel-workers=2 binlog-checksum=CRC32 master-verify-checksum=1 slave-sql-verify-checksum=1 binlog-rows-query-log_events=1 server-id=1 report-port=3306 port=3306 datadir=/mydata/data innodb_file_per_table = ON socket=/tmp/mysql.sock report-host=172.16.1.101 启动服务并查看gtid是否生效 [[email protected] mysql]# service mysqld start Starting MySQL......... [ OK ] [[email protected] mysql]# mysql Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 2 Server version: 5.6.26-log MySQL Community Server (GPL) Type ‘help;‘ or ‘\h‘ for help. Type ‘\c‘ to clear the buffer. mysql> SHOW GLOBAL VARIABLES LIKE ‘%gtid%‘; +---------------------------------+-------+ | Variable_name | Value | +---------------------------------+-------+ | binlog_gtid_simple_recovery | OFF | | enforce_gtid_consistency | ON | | gtid_executed | | | gtid_mode | ON | | gtid_owned | | | gtid_purged | | | simplified_binlog_gtid_recovery | OFF | +---------------------------------+-------+ 7 rows in set (0.00 sec) 查看master的uuid mysql> SHOW GLOBAL VARIABLES LIKE ‘%uuid%‘; +---------------+--------------------------------------+ | Variable_name | Value | +---------------+--------------------------------------+ | server_uuid | dfc512d8-bc12-11e5-97ec-000c29fe8238 | +---------------+--------------------------------------+ 1 row in set (0.00 sec)
2、编辑slave的配置文件
编辑配置文件，就在当前目录下(/usr/local/mysql) [[email protected] mysql]# vim my.cnf [mysqld] binlog-format=ROW log-slave-updates=true gtid-mode=on enforce-gtid-consistency=true master-info-repository=TABLE relay-log-info-repository=TABLE sync-master-info=1 slave-parallel-workers=2 binlog-checksum=CRC32 master-verify-checksum=1 slave-sql-verify-checksum=1 binlog-rows-query-log_events=1 server-id=11 report-port=3306 port=3306 log-bin=mysql-bin.log datadir=/mydata/data socket=/tmp/mysql.sock report-host=172.16.1.105 启动服务并查看gtid是否生效 [[email protected] mysql]# service mysqld start Starting MySQL..... [ OK ] [[email protected] mysql]# mysql Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 1 Server version: 5.6.26-log MySQL Community Server (GPL) Type ‘help;‘ or ‘\h‘ for help. Type ‘\c‘ to clear the buffer. mysql> SHOW GLOBAL VARIABLES LIKE ‘%gtid%‘; +---------------------------------+-------+ | Variable_name | Value | +---------------------------------+-------+ | binlog_gtid_simple_recovery | OFF | | enforce_gtid_consistency | ON | | gtid_executed | | | gtid_mode | ON | | gtid_owned | | | gtid_purged | | | simplified_binlog_gtid_recovery | OFF | +---------------------------------+-------+ 7 rows in set (0.00 sec) mysql> SHOW GLOBAL VARIABLES LIKE ‘%uuid%‘; +---------------+--------------------------------------+ | Variable_name | Value | +---------------+--------------------------------------+ | server_uuid | ec8230c2-bc18-11e5-9813-000c296634d1 | +---------------+--------------------------------------+ 1 row in set (0.09 sec)
3、master建立复制账号
