Mysql的源码编译安装

1.下载mysql安装包，下载完成后上传到linux里面（我一般放在/usr/local/src)（下载地址：https://dev.mysql.com/downloads/mysql/）

 

2.安装编译所需的常用组件和依赖包

yum -y install gcc gcc-c++ ncurses ncurses-devel bison libgcrypt perl make cmake

注意：在cmake安装mysql的时候需要安装openssl或者openssl-devel，不然会报错 ：yum -y install openssl openssl-devel

3.上传boost1.5.9，个人将其解压在/usr/loacl目录下（后面在cmake编译安装时需要指定boost的路径）

4.创建mysql用户组和用户，用来运行mysql服务器， -g指定用户组, -r创建系统用户

[root@iZ2864f6btwZ src]# groupadd mysql

[root@iZ2864f6btwZ src]# useradd -r -g mysql -s /bin/false-M mysql

5.解压MySQL，进入 mysql-5.7.19 目录

[root@iZ2864f6btwZ src]# tar zxvf mysql-boost-5.7.19.tar.gz 

[root@iZ2864f6btwZ src]# cd mysql-5.7.19/

6.在进入mysql的源码包的路径下后执行以下语句：

cmake . -DWITH_BOOST=/usr/local/boost -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -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

每个参数的含义解释：百度，哈哈哈哈，实在太多了

 

 7.完成后再次执行：make && make install

8.新建文件夹

mkdir -p /data/{3306,3307}/data 

此处注意：本人部署多实例，实际情况按照个人选择

9. 将mysql下的命令加入到系统

vim /etc/profile
export PATH=/usr/local/mysql/bin:$PATH
source /etc/profile

10.初始化数据库
mysqld --defaults-file=/data/3306/my.cnf --initialize-insecure --user=mysql

mysqld --defaults-file=/data/3306/my.cnf --user=mysql &

11.登录修改密码（mysql'修改密码一共有三种方式）
mysql -uroot -S /data/3306/mysql.sock

SET PASSWORD=PASSWORD('123456');

12.Mysql的关闭
注意：一定要用mysqladmin关闭
mysqladmin -u root -p -S /data/3306/mysql.sock shutdown
