编译安装mysql56
编译
# linux下用cmake编译安装mysql-5.6.35
# 安装cmake
sudo pacman -S cmake
wget http://dev.mysql.com/get/Downloads/MySQL-5.6/mysql-5.6.35.tar.gz
tar zxvf mysql-5.6.35.tar.gz
cd mysql-5.6.35
# 创建数据存放目录
mkdir -p /vhs/mysql/mysql56
# 创建用户及用户组并指定之上的目录，用户及用户组
sudo useradd -M mysql -s /sbin/nologin
sudo chown -R mysql.mysql /vhs/mysql/mysql56

-DCMAKE_INSTALL_PREFIX=dir_name 设置mysql安装目录
-DMYSQL_UNIX_ADDR=file_name 设置监听套接字路径，这必须是一个绝对路径名。默认为/tmp/mysql.sock
-DDEFAULT_CHARSET=charset_name 设置服务器的字符集。缺省情况下，MySQL使用latin1的（CP1252西欧）字符集。cmake/character_sets.cmake文件包含允许的字符集名称列表。
-DDEFAULT_COLLATION=collation_name 设置服务器的排序规则。
-DWITH_INNOBASE_STORAGE_ENGINE=1
-DWITH_ARCHIVE_STORAGE_ENGINE=1
-DWITH_BLACKHOLE_STORAGE_ENGINE=1
-DWITH_PERFSCHEMA_STORAGE_ENGINE=1
存储引擎选项：MyISAM，MERGE，MEMORY，和CSV引擎是默认编译到服务器中，并不需要明确地安装。
静态编译一个存储引擎到服务器，使用-DWITH_engine_STORAGE_ENGINE= 1
可用的存储引擎值有：ARCHIVE, BLACKHOLE, EXAMPLE, FEDERATED, INNOBASE (InnoDB), PARTITION (partitioning support), 和PERFSCHEMA (Performance Schema)
-DMYSQL_DATADIR=dir_name 设置mysql数据库文件目录
-DMYSQL_TCP_PORT=port_num 设置mysql服务器监听端口，默认为3306
-DENABLE_DOWNLOADS=bool 是否要下载可选的文件。例如，启用此选项（设置为1），cmake将下载谷歌所使用的测试套件运行单元测试。

配置
# 初始化权限
# 进入/vhs/mysql/mysql56/
sudo scripts/mysql_install_db --user=mysql --basedir=/vhs/mysql/mysql56/ --datadir=/vhs/mysql/mysql56/
# 修改my.cnf,如下面
nano my.cnf
# 创建
sudo mkdir /vhs/mysql/mysql56/tmp
