今天给小伙伴们介绍一下Mysql5.7源码安装，在安装过程中还是碰到了一些问题，下面介绍安装步骤时，会告诉大家问题在哪儿，怎么解决的，废话不多说，下面就可以说说安装全过程

1.创建用户

groupadd mysql

useradd -d /home/mysql -g mysql mysql

echo "mysql123" | passwd --stdin mysql

2.修改limit参数值

echo "* soft nofile 65536" >> /etc/security/limits.conf

echo "* hard nofile 65536" >> /etc/security/limits.conf

3.安装依赖包

yum install -y cmake gcc gcc-c++ ncurses-devel bison zlib libxml openssl openssl-devel

4.创建目录

mkdir -p /u02/mysql

mkdir -p /u02/conf

mkdir -p /u02/data/3308

mkdir -p /u02/log/3308/iblog

mkdir -p /u02/log/3308/binlog

mkdir -p /u02/run/3308

mkdir -p /u02/tmp/3308

chown -R mysql:mysql /u02

chmod -R 755 /u02

5.下载源码包

wget http://cdn.mysql.com/Downloads/MySQL-5.7/mysql-5.7.26.tar.gz

6.源码编译安装

cmake \

-DCMAKE_INSTALL_PREFIX=/u02/mysql \

-DMYSQL_DATADIR=/u02/data/3308 \

-DDEFAULT_CHARSET=utf8 \

-DDEFAULT_COLLATION=utf8_general_ci \

-DEXTRA_CHARSETS=all \

-DWITH_SSL=yes \

-DWITH_EMBEDDED_SERVER=1 \

-DENABLED_LOCAL_INFILE=1 \

-DWITH_MYISAM_STORAGE_ENGINE=1 \

-DWITH_INNOBASE_STORAGE_ENGINE=1 \

-DWITH_ARCHIVE_STORAGE_ENGINE=1 \

-DWITH_BLACKHOLE_STORAGE_ENGINE=1 \

-DWITH_FEDERATED_STORAGE_ENGINE=1 \

-DWITH_PARTITION_STORAGE_ENGINE=1 \

-DMYSQL_UNIX_ADDR=/u02/run/3308/mysql.sock \

-DMYSQL_TCP_PORT=3308 \

-DDOWNLOAD_BOOST=1 \

-DWITH_BOOST=/usr/local/boost \

-DSYSCONFDIR=/etc \

-DWITH_READLINE=on

这里对每个编译参数都解释一下其作用

##安装目录

DCMAKE_INSTALL_PREFIX=/u02/mysql

##数据存放目录

DMYSQL_DATADIR=/u02/data/3308

##默认数据库字符集

DDEFAULT_CHARSET=utf8

##新建数据库默认字符集

DDEFAULT_COLLATION=utf8_general_ci

##安装所有扩展字符集

DEXTRA_CHARSETS=all

##支持 SSL

DWITH_SSL=yes

##是否建立了嵌入式服务器

DWITH_EMBEDDED_SERVER=1 \

##是否允许本地文件导入

DENABLED_LOCAL_INFILE=1 \

##存储引擎

DWITH_MYISAM_STORAGE_ENGINE=1 \

DWITH_INNOBASE_STORAGE_ENGINE=1 \

DWITH_ARCHIVE_STORAGE_ENGINE=1 \

DWITH_BLACKHOLE_STORAGE_ENGINE=1 \

DWITH_FEDERATED_STORAGE_ENGINE=1 \

DWITH_PARTITION_STORAGE_ENGINE=1 \

##sock文件路径

DMYSQL_UNIX_ADDR=/u02/run/3308/mysql.sock

##数据库访问端口

DMYSQL_TCP_PORT=3308 \

##MySQL5.7.5必须要开启Boost库

DDOWNLOAD_BOOST=1 \

##Boost库文件存放路径

DWITH_BOOST=/usr/local/boost \

##mysql配置文件目录

DSYSCONFDIR=/etc \

##启用readline库支持

DWITH_READLINE=on

在这里要提醒一下，因为安装的mysql版本是5.7，如果安装的服务器不能联网，需要提前下载Boost库包，如果不下载，编译是无法通过的，下载方法如下所示

http://sourceforge.net/projects/boost/files/boost/1.59.0/boost_1_59_0.tar.gz

下载完成，放到编译参数指定的目录位置即可，DWITH_BOOST=/usr/local/boost,然后开始进行make和make install

7.设置配置参数，这里提供的参数已经包含配置主从复制的参数，按照下面的参数启动数据库，非常简单就可以搭建好主从复制

cd /u02/conf

vi my3308.cnf

8.初始化多实例数据库

切换到mysql用户

su - mysql

# 初始化数据库实例

/u02/mysql/bin/mysqld --defaults-file=/u02/conf/my3308.cnf --initialize --user=mysql

# 使用独立参数启动实例

/u02/mysql/bin/mysqld_safe --defaults-file=/u02/conf/my3308.cnf &

# 登陆3308实例

/u02/mysql/bin/mysql --socket=/u02/run/3308/mysql.sock

修改root密码

ALTER USER 'root'@'localhost' IDENTIFIED BY 'root';

flush privileges;

# 关闭实例

/u02/mysql/bin/mysqladmin --socket=/u02/run/3308/mysql.sock shutdown &

到这里Mysql5.7源码安装就结束了
