上一篇已经说过部署的初衷,如有不清楚的,可以看下上篇的前言或在评论区留言给我。

此篇主要介绍安装mysql的方法,php会要用到mysql连接数据库

准备:

mysql官网:mysql.com

源码目录:/usr/local/src

mysql官方提供官方库、源码、二进制包三种安装方式。此文会分别介绍官方库、源码包的安装方式,对于二进制包,下载后可直接使用。

此文介绍mysql 5.6 社区版,在下载时不要选择错了

安装:

使用官方库安装:

1 配置mysql.repo

vim /etc/yum.repos.d/mysql.repo # Enable to use MySQL 5.6 [mysql56-community] name=MySQL 5.6 Community Server baseurl=http://repo.mysql.com/yum/mysql-5.6-community/el/6/$basearch/ enabled=1 gpgcheck=1

2 创建mysql_pubkey.asc

可参考http://dev.mysql.com/doc/refman/5.6/en/checking-gpg-signature.html

vim mysql_pubkey.asc-----BEGIN PGP PUBLIC KEY BLOCK----- Version: GnuPG v1.4.9 (SunOS) mQGiBD4+owwRBAC14GIfUfCyEDSIePvEW3SAFUdJBtoQHH/nJKZyQT7h9bPlUWC3

3 导入mysql公钥

gpg --import mysql_pubkey.asc

4 验证签名

gpg --keyserver keys.gnupg.net --recv-keys 5072E1F5

5 安装mysql

如遇超时,可以先yum makecache下

yum install mysql-community-server

6 启动mysql服务

service mysqld start

7 确认安装

可以设置mysql root口令以及删除空帐号等

mysql_secure_installation

源码安装

安装编译依赖

yum install -y wget ncurses-devel

1 在官方下载mysql源码包

wget http://dev.mysql.com/get/Downloads/MySQL-5.6/mysql-5.6.34.tar.gz

2 解压

tar zxf mysql-5.6.34.tar.gz

3 添加mysql用户组及用户

groupadd mysql useradd -g mysql mysql -s /bin/false

4 创建数据目录,并赋予权限

mkdir -p /data/mysql chown mysql:mysql /data/mysql

5 配置编译参数

cd mysql-5.6.12 cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \ -DMYSQL_UNIX_ADDR=/tmp/mysql.sock \ -DDEFAULT_CHARSET=utf8 \ -DDEFAULT_COLLATION=utf8_general_ci \ -DWITH_EXTRA_CHARSETS:STRING=utf8,gbk \ -DWITH_INNOBASE_STORAGE_ENGINE=1 \ -DWITH_READLINE=1 \ -DENABLED_LOCAL_INFILE=1 \ -DMYSQL_DATADIR=/data/mysql/ \ -DMYSQL_TCP_PORT=3306

6 编译

make make install

7 设置mysql

cd /usr/local/mysql chown -R mysql . chgrp -R mysql . #初始化数据库 scripts/mysql_install_db --user=mysql chown -R root . chown -R mysql data bin/mysqld_safe --user=mysql & #配置服务 cp support-files/mysql.server /etc/init.d/mysqld

可在初始化数据库时附加参数指定配置

scripts/mysql_install_db --user=mysql \          --basedir=/usr/local/mysql \          --datadir=/data/mysql

8 启动mysql服务

service mysql start

9 默认初始化数据库后 root 密码为空,可通过mysql_secure_installation 配置mysql安全

bin/mysql_secure_installation

10 配置防火墙 开启3306端口

iptables -I INPUT -p tcp --dport 3306 -j ACCEPT

注:若没有安装相关依赖,可能会看到类似如下错误。错误的结尾给出了各系统对应的依赖包,安装后需要清除cmake 缓存,直接删除CMakeCache.txt 文件,重新配置编译即可

-- Could NOT find Curses (missing: CURSES_LIBRARY CURSES_INCLUDE_PATH)
CMake Error at cmake/readline.cmake:85 (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.

默认初始化数据库后,需要修改my.cnf配置文件相关配置为实际值
