centos7中编译安装mysql5.7

1.准备软件包并安装依赖
cmake：2.8.12 点击下载
boost：boost_1_59_0 http://www.boost.org/users/download/#history
mysql：mysql-5.7.18 https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.18.tar.gz

cmake安装，boost解压移动到/usr/local/boost

yum -y install gcc gcc-c++ ncurses ncurses-devel 

2.创建mysql用户及用户组

groupadd -r mysql && useradd -r -g mysql -s /bin/false -M mysql

3.创建mysql安装目录，并授权
mkdir /data/modules/mysql5.7
mkdir /data/modules/mysql5.7/data
chown -R mysql:mysql /data/modules/mysql5.7
chown -R mysql:mysql /data/modules/mysql5.7/data

4.解压mysql安装包，开始安装到指定目录

cmake -DCMAKE_INSTALL_PREFIX=/data/modules/mysql5.7 -DMYSQL_DATADIR=/data/modules/mysql5.7/data -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DMYSQL_TCP_PORT=3306 -DMYSQL_USER=mysql -DWITH_MYISAM_STORAGE_ENGINE=1 -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_ARCHIVE_STORAGE_ENGINE=1 -DWITH_BLACKHOLE_STORAGE_ENGINE=1 -DWITH_MEMORY_STORAGE_ENGINE=1 -DDOWNLOAD_BOOST=1 -DWITH_BOOST=/usr/local/boost  -DMYSQL_USER=mysql

查看选项

cmake . -LAH # all params with help text 
ccmake . # interactive display

出错需要重新编译时需执行

make clean 
rm -f CMakeCache.txt

5.设置MySQL的配置文件my.cnf

mv /etc/my.cnf /etc/my.cnf.bak 
vi /etc/my.cnf 

配置如下：

[mysqld] 
basedir = /data/modules/mysql5.7
datadir = /data/modules/mysql5.7/data
log-error = /data/modules/mysql5.7/data/error.log 
port = 3306
socket=/data/modules/mysql5.7/data/mysql.sock

[mysqld_safe] 
pid-file=/data/modules/mysql5.7/data/mysqld.pid

6.初始化MySQL自身的数据库

mysqld --initialize-insecure --user=mysql --basedir=/data/modules/mysql5.7 --datadir=/data/modules/mysql5.7/data

ls -lrt /data/modules/mysql5.7/data/   //命令查看是否生成了MySQL自身的数据库文件

7.启动MySQL服务

mkdir /var/log/mysql/error.log

mysqld_safe --user=mysql --datadir=/data/modules/mysql5.7/data --log-error=/var/log/mysql/error.log

mysql_secure_installation
(ln -s /data/modules/mysql5.7/data/mysql.sock /tmp/mysql.sock)
mysqladmin -uroot password 123456 –socket=/data/modules/mysql5.7/data/mysql.sock(/tmp/mysql.sock)

8.开机运行

cp /data/modules/mysql5.7/support-files/mysql.server /etc/init.d/mysqld 
chmod +x /etc/init.d/mysqld 
chkconfig --add mysqld
chkconfig mysqld on
