Centos7 mysql-community-5.7.11编译安装

安装环境

[root@localhost ~]# cat /etc/centos-release
CentOS Linux release 7.0.1406 (Core)

0x01 准备工作

1、到mysql官网下载mysql-community-5.7.11-1.el7.src.rpm源码包

rpm -ih mysql-community-5.7.11-1.el7.src.rpm会在用户目录下生成一个rpmbuild，从SOURCES文件夹内可以获得源码mysql-5.7.11.tar.gz，解压进入源码目录准备安装

2、因为mysql需要使用cmake编译，直接从yum从光盘的源中找到cmake

[root@localhost ~]# yum info cmake

名称 ：cmake
架构 ：x86_64
版本 ：2.8.11
发布 ：4.el7
大小 ：6.7 M

3、准备开发环境yum groupinstall Additional Development，yum groupinstall Development tools之前的版本是Development tools和Development Libraries两个软件包组，我这里没有安装，因为只需要gcc和gcc-c++

0x03 安装过程（gcc / boost_1_59_0 / CURSES_LIBRARY ）

[root@localhost ~]# cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_DATADIR=/mymnt/sqldata -DSYSCONFDIR=/etc -DWITH_MYISAM_STORAGE_ENGINE=1 -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_ARCHIVE_STORAGE_ENGINE=1  -DWITH_MEMORY_STORAGE_ENGINE=1 -DWITH_READLINE=1  -DMYSQL_UNIX_ADDR=/var/run/mysql/mysql.sock -DWITH-LIBWRAP=0 -DENABLE_DOWNLOADS=1 -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci

这是没有安装gcc和gcc-c++

[root@localhost mysql-5.7.11]# yum install gcc gcc-c++

再cmake一次

-- MySQL 5.7.11
-- Packaging as: mysql-5.7.11-Linux-x86_64
-- Looked for boost/version.hpp in and
-- BOOST_INCLUDE_DIR BOOST_INCLUDE_DIR-NOTFOUND
-- LOCAL_BOOST_DIR
-- LOCAL_BOOST_ZIP
-- Could not find (the correct version of) boost.
-- MySQL currently requires boost_1_59_0

CMake Error at cmake/boost.cmake:81 (MESSAGE):
You can download it with -DDOWNLOAD_BOOST=1 -DWITH_BOOST=<directory>

This CMake script will look for boost in <directory>. If it is not there,
it will download and unpack it (in that directory) for you.

If you are inside a firewall, you may need to use an http proxy:

export http_proxy=http://example.com:80

Call Stack (most recent call first):
cmake/boost.cmake:238 (COULD_NOT_FIND_BOOST)
CMakeLists.txt:443 (INCLUDE)

-- Configuring incomplete, errors occurred!

这个就已经说明了You can download it with -DDOWNLOAD_BOOST=1 -DWITH_BOOST=<directory>，Boost库是一个经过千锤百炼、可移植、提供源代码的C++库,作为标准库的后备,是C++标准化进程的发动机之一。

先从boost官网下载这个库boost_1_59_0.tar.gz

解压后把目录添加到-DWITH_BOOST编译选项中

继续编译报错如下

-- Could NOT find Curses (missing: CURSES_LIBRARY CURSES_INCLUDE_PATH)
CMake Error at cmake/readline.cmake:64 (MESSAGE):
Curses library not found. Please install appropriate package,

remove CMakeCache.txt and rerun cmake.On Debian/Ubuntu, package name is libncurses5-dev, on Redhat and derivates it is ncurses-devel.

cmake/readline.cmake:107 (FIND_CURSES)
cmake/readline.cmake:181 (MYSQL_USE_BUNDLED_EDITLINE)
CMakeLists.txt:471 (MYSQL_CHECK_EDITLINE)

这个错误是说明缺少Curses库yum install ncurses-devel，需要注意的是每次编译错误都要移除CMakeCache.txt，最后出现 Build files have been written 即成功

CMake Warning:
Manually-specified variables were not used by the project:

DOWNLOAD_BOOST
WITH-LIBWRAP
WITH_MEMORY_STORAGE_ENGINE
WITH_READLINE

-- Build files have been written to: /root/mysql-5.7.11

使用make大约两个小时的样子编译完成，到百分之五十几的时候停留的时间比较长。

make install

出现一堆安装信息即完成安装

0x04 安装后目录创建

socket=/var/run/mysql/mysql.sock
basedir = /usr/local/mysql
datadir = /mymnt/sqldata
socket=/var/run/mysql/mysql.sock
log-error = /var/log/mysql/error.log
pid-file = /var/log/mysql/mysql.pid

如配置文件关于目录相关的部分，我们需要创建/var/run/mysql ,  /mymnt/sqldata  ,  /var/log

创建mysql用户和组，将数据目录  /mymnt/sqldata 和安装目录/var/run/mysql的属主（组）更改成mysql

 

[root@localhost mysql]# groupadd -r mysql
[root@localhost mysql]# useradd -r -g mysql -s /sbin/nologin mysql

[root@localhost mysql]# mkdir /var/run/mysql
[root@localhost mysql]# mkdir /var/log/mysql
[root@localhost mysql]# chown mysql:mysql /var/run/mysql/
[root@localhost mysql]# chown mysql:mysql /var/log/mysql/
[root@localhost mysql]# chown mysql:mysql /mymnt/sqldata/
[root@localhost mysql]# chown -R mysql:mysql /usr/local/mysql

 

0x05 初始化

1、mysql-5.7版本的my.cnf文件在support-files/下并没有模板文件，自行添加配置文件

2、将安装目录下support-files/mysql.server 启动脚本复制到 /etc/init.d/mysqld，以便实现开机启动。也可以[root@localhost mysql]# ./support-files/mysql.server start 临时启动

未启动时执行mysql命令会报错如下：

[root@localhost mysql]# mysql
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysql/mysql.sock' (2)

3、添加环境变量以便使用初始化命令 export PATH=/usr/local/mysql/bin:$PATH

4、初始化

mysqld --initialize-insecure --user=mysql --basedir=/usr/local/mysql --datadir=/mymnt/sqldata

0x06 其他

1、mysqld_safe

　　mysqld 和 mysqld_safe都可以启动mysql。直接运行mysqld程序来启动MySQL服务的方法很少见，mysqld_safe脚本会在启动MySQL服务器后继续监控其运行情况，并在其死机时重新启动它。

        我们可以发现这是一个shell脚本，在Unix和NetWare中推荐使用mysqld_safe来启动mysqld服务器。mysqld_safe增加了一些安全特性，例如当出现错误时重启服务器并向错误日志文件写入运行时间信息。

[root@localhost mysql]# file bin/mysqld
bin/mysqld: ELF 64-bit LSB executable, x86-64, version 1 (GNU/Linux), dynamically linked (uses shared libs), for GNU/Linux 2.6.32, BuildID[sha1]=0x772828c9d330090391cd89dbe699f041a378944d, not stripped
[root@localhost mysql]# file bin/mysqld_safe
bin/mysqld_safe: POSIX shell script, ASCII text executable

2、mysql_secure_installation

MySQL安全配置向导，运行mysql_secure_installation会执行几个设置：
  a)为root用户设置密码
  b)删除匿名账号
  c)取消root用户远程登录
  d)删除test库和对test库的访问权限
  e)刷新授权表使修改生效
通过这几项的设置能够提高mysql库的安全。建议生产环境中mysql安装这完成后一定要运行一次mysql_secure_installation

3、为了方便其他程序调用（如php），将MySQL数据库的动态链接库目录添加至系统链接库，echo "/usr/local/mysql/lib" > /etc/ld.so.conf.d/mysql.conf

0x07 附：my.cnf示例
