MySQL5.7主从编译安装配置
mysql5.7

1、依赖安装

yum install -y  gcc gcc-c++ cmake ncurses ncurses-devel bison
yum install -y krb5 krb5-devel libidn libidn-devel openssl openssl-devel -y



2、创建用户
useradd -s /sbin/nologin mysql
mkdir -p /data/mysql/data
chown -R mysql:mysql /data/mysql

3、解压包
tar -zxvf mysql-boost-5.7.28.tar.gz

4、编译安装
cd mysql-boost-5.7.28

cmake -DWITH_BOOST=boost -DCMAKE_INSTALL_PREFIX=/data/mysql -DMYSQL_DATADIR=/data/mysql/data -DWITH_MYISAM_STORAGE_ENGINE=1 -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_FEDERATED_STORAGE_ENGINE=1 -DWITH_BLACKHOLE_STORAGE_ENGINE=1 -DWITH_EXAMPLE_STORAGE_ENGINE=1 -DWITH_PARTITION_STORAGE_ENGINE=1 -DWITH_MEMORY_STORAGE_ENGINE=1 -DWITH_READLINE=1 -DENABLED_LOCAL_INFILE=1 -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DEXTRA_CHARSETS=gbk,gb2312,utf8,ascii -DMYSQL_USER=mysql -DWITH_ZLIB=bundled -DWITH_READLINE=1 -DWITH_FAST_MUTEXES=1 -DWITH_EMBEDDED_SERVER=1 -DWITH_DEBUG=0 -DWITH_SSL=system

make &&  make install

5、创建配置文件/etc/my.cnf
5.1、主MySQL配置
[client]
port        = 3306
socket      = /tmp/mysql.sock

[mysqld]
port        = 3306
socket      = /tmp/mysql.sock
user = mysql



basedir = /data/mysql
datadir = /data/mysql/data
pid-file = /data/mysql/mysql.pid

log_error = /data/mysql/mysql-error.log
slow_query_log = 1
long_query_time = 1
slow_query_log_file = /data/mysql/mysql-slow.log



skip-external-locking
key_buffer_size = 32M
max_allowed_packet = 1024M
table_open_cache = 128
sort_buffer_size = 768K
net_buffer_length = 8K
read_buffer_size = 768K
read_rnd_buffer_size = 512K
myisam_sort_buffer_size = 8M
thread_cache_size = 16
query_cache_size = 16M
tmp_table_size = 32M
performance_schema_max_table_instances = 1000

explicit_defaults_for_timestamp = true
#skip-networking
max_connections = 500
max_connect_errors = 100
open_files_limit = 65535

log_bin=mysql-bin
binlog_format=mixed
server_id   = 232
expire_logs_days = 10
early-plugin-load = ""

default_storage_engine = InnoDB
innodb_file_per_table = 1
innodb_buffer_pool_size = 128M
innodb_log_file_size = 32M
innodb_log_buffer_size = 8M
innodb_flush_log_at_trx_commit = 1
innodb_lock_wait_timeout = 50

character_set_server=utf8
init_connect='SET NAMES utf8'
# mysql master slave
# 标识
server-id = 1
#此参数表示启用binlog并指定日志文件路径
log_bin=master-bin
#此参数指定二进制索引文件路径
log_bin_index=master-bin.index

#配置记录binlog日志的数据库,有binlog日志的数据库会被同步,多个数据库用逗号隔开
binlog_do_db=binlog_db

binlog_format = ROW
# 忽略不被同步
binlog_ignore_db=information_schema
binlog_ignore_db=performation_schema
binlog_ignore_db=sys
binlog_ignore_db=mysql

[mysqldump]
quick
max_allowed_packet = 16M

[mysql]
no-auto-rehash

[myisamchk]
key_buffer_size = 32M
sort_buffer_size = 768K
read_buffer = 2M
write_buffer = 2M

5.2、从配置
[client]
port        = 3306
socket      = /tmp/mysql.sock

[mysqld]
port        = 3306
socket      = /tmp/mysql.sock
user = mysql



basedir = /data/mysql
datadir = /data/mysql/data
pid-file = /data/mysql/mysql.pid

log_error = /data/mysql/mysql-error.log
slow_query_log = 1
long_query_time = 1
slow_query_log_file = /data/mysql/mysql-slow.log



skip-external-locking
key_buffer_size = 32M
max_allowed_packet = 1024M
table_open_cache = 128
sort_buffer_size = 768K
net_buffer_length = 8K
read_buffer_size = 768K
read_rnd_buffer_size = 512K
myisam_sort_buffer_size = 8M
thread_cache_size = 16
query_cache_size = 16M
tmp_table_size = 32M
performance_schema_max_table_instances = 1000

explicit_defaults_for_timestamp = true
#skip-networking
max_connections = 500
max_connect_errors = 100
open_files_limit = 65535

log_bin=mysql-bin
binlog_format=mixed
server_id   = 232
expire_logs_days = 10
early-plugin-load = ""

default_storage_engine = InnoDB
innodb_file_per_table = 1
innodb_buffer_pool_size = 128M
innodb_log_file_size = 32M
innodb_log_buffer_size = 8M
innodb_flush_log_at_trx_commit = 1
innodb_lock_wait_timeout = 50

character_set_server=utf8
init_connect='SET NAMES utf8'

# mysql master slave
# 标识
server-id = 2
#启动中继日志服务并设置地址,中继日志就是存储主库过来的binlog日志
relay-log = slave-relay-bin
#中继日志二进制文件索引地址
relay-log-index = slave-relay-bin.index

[mysqldump]
quick
max_allowed_packet = 16M

[mysql]
no-auto-rehash

[myisamchk]
key_buffer_size = 32M
sort_buffer_size = 768K
read_buffer = 2M
write_buffer = 2M

6、初始化数据库(主从都需要配置,默认root密码为空,根据实际需求修改root密码)
./mysqld --initialize-insecure --user=mysql --basedir=/data/mysql --datadir=/data/mysql/data

7、在主库创建授权远程连接用户
mysql>CREATE USER 'rep1'@'%' IDENTIFIED BY '123456'; Query OK, 0 rows affected (0.01 sec)
mysql>GRANT REPLICATION SLAVE, REPLICATION CLIENT ON *.* TO 'rep1'@'%'; Query OK, 0 rows affected (0.00 sec)

mysql> show master status;
+-------------------+----------+--------------+--------------------------------------------------+-------------------+
| File              | Position | Binlog_Do_DB | Binlog_Ignore_DB                                 | Executed_Gtid_Set |
+-------------------+----------+--------------+--------------------------------------------------+-------------------+
| master-bin.000001 |      398 | binlog_db    | information_schema,performation_schema,sys,mysql |                   |
+-------------------+----------+--------------+--------------------------------------------------+-------------------+
1 row in set (0.00 sec)



8、从库连接mysql主数据库,登陆到从库上执行
mysql> change master to master_host='主库ip地址', master_port=3306, master_user='repl', master_password='123456', master_log_file='master-bin.000001', master_log_pos=398;

mysql> start slave;



mysql> show slave status\G;
