MySQL5.7源码编译安装+主从搭建

1. 源码包需求 将源码包加入到/usr/local/package下
   源码包下载链接：
   https://pan.baidu.com/s/1bBfG6z9TlErw5y58eGe8Hw 密码：wlld
   cmake-3.5.0.tar.gz
   mysql-5.7.17.tar.gz
   boost_1_59_0.tar.gz

2. yum安装依赖包
   yum -y install gcc gcc-c++ make cmake ncurses ncurses-devel man ncurses libxml2 libxml2-devel openssl-devel bison bison-devel

3. 解压boost, 5.7需要boost
   cd /usr/local/package/
   tar zxvf boost_1_59_0.tar.gz
   mv boost_1_59_0 ../

4. 解压cmake, 并安装
   cd /usr/local/package/
   tar -zxvf cmake-3.5.0.tar.gz && cd cmake-3.5.0/
   ./configure --prefix=/usr/local/cmake
   gmake && make install

5. 使用cmake编译安装mysql
   cd /usr/local/package/
   tar -zxvf mysql-5.7.17.tar.gz && cd mysql-5.7.17/
   /usr/local/cmake/bin/cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DWITH_BOOST=/usr/local/boost_1_59_0 -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci
   make && make install

配置mysql

cp /etc/my.cnf /etc/my.cnf.bak
rm -rf /etc/my.cnf

mysql初始化

cd /usr/local/mysql
useradd -r mysql
chown -R mysql .
chgrp -R mysql .

创建数据目录

mkdir -p /usr/local/mysql/data/
bin/mysqld --initialize-insecure --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data
bin/mysql_ssl_rsa_setup --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data
chown -R root .
chown -R mysql data/

复制配置文件

cp support-files/my-default.cnf /etc/my.cnf

使用service管理

cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld

将mysql目录加入到环境变量

vi /etc/profile
{
PATH=/usr/local/mysql/bin:/usr/local/mysql/lib:$PATH
}
source /etc/profile

修改配置文件

vi /etc/my.cnf
{
datadir = /usr/local/mysql/data
}

service mysqld start
ps aux | grep mysqld
mysql -uroot -p

修改root密码

grant all on . to 'root'@'%' identified by 'GfsdX1F8pYL@1s';
set password = password('GfsdX1F8pYL@1s');

mysql主从搭建(https://www.jianshu.com/p/b8422c2fa80e)

主: 192.168.2.22
从: 192.168.2.23
1 修改主库和从库配置文件
主库
$ vim /etc/my.cnf

# 启用二进制日志
log-bin=mysql-bin
# 服务器唯一ID
server-id=22

从库:
$ vim /etc/my.cnf

# 启用二进制日志，可不配
log-bin=mysql-bin
# 服务器唯一ID
server-id=23

重启

service mysqld restart;

在主库建一个专用来备份的 MySQL 账户

grant replication slave,reload,super on *.* to 'repl'@'%' identified by 'repl';
flush privileges;
show master status;

mysql> show master status;
+------------------+----------+--------------+------------------+-------------------+
| File             | Position | Binlog_Do_DB | Binlog_Ignore_DB | Executed_Gtid_Set |
+------------------+----------+--------------+------------------+-------------------+
| mysql-bin.000001 |      154 |              |                  |                   |
+------------------+----------+--------------+------------------+-------------------+

更改从库配置; 指定主库复制地址, 复制用户, 密码, 二进制文件名称以及位置

change master to master_host='192.168.2.22',master_user='repl',master_password='repl',master_log_file='mysql-bin.000001',master_log_pos=154;

开启复制

start slave;

查看状态

show slave status\G

以下两项成功,即完成搭建

Slave_IO_Running: Connecting
Slave_SQL_Running: Yes

在主库执行DDL, 查看从库复制状态, 观察有没有报错
