安装依赖

(1)cmake是新版MySQL的编译工具

sudo yum install gcc gcc-c++ pcre pcre-devel openssl openssl-devel

sudo yum install zlib zlib-devel cmake ncurses ncurses-devel bison bison-devel

如下的几个依赖在CentOS7中需要安装,CentOS6不需要

sudo yum install perl perl-devel autoconf

安装boost

如果安装的MySQL5.7及以上的版本，在编译安装之前需要安装boost,因为高版本mysql需要boots库的安装才可以正常运行。否则会报CMake Error at cmake/boost.cmake:81 错误

1. 切换到/usr/local目录，然后在这个目录下下载boost
   
   MySQL5.7.24要求boost的版本是1.59，更高版本的不适用MySQL5.7.24

   wget http://www.sourceforge.net/projects/boost/files/boost/1.59.0/boost_1_59_0.tar.gz
   

2. 解压并改名

   tar zxvf boost_1_59_0.tar.gz
   
   mv boost_1_59_0 boost
   

3. 在预编译安装MySQL时要加上-DWITH_BOOST=/usr/local/boost

编译安装MySQL

# 添加MySQL用户

useradd -s /sbin/nologin -M mysql

# 下载MySQL

wget https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.24.tar.gz

# 解压MySQL

tar zxvf mysql-5.7.24.tar.gz

# 进到MySQL目录

cd mysql-5.7.24

# 预编译

cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql-5.7.24 \

-DWITH_BOOST=/usr/local/boost \

-DMYSQL_UNIX_ADDR=/usr/local/mysql-5.7.24/tmp/mysql.sock \

-DMYSQL_DATADIR=/usr/local/mysql-5.7.24/data \

-DDEFAULT_CHARSET=utf8mb4 \

-DDEFAULT_COLLATION=utf8mb4_general_ci \

-DWITH_EXTRA_CHARSETS=all \

-DWITH_MYISAM_STORAGE_ENGINE=1 \

-DWITH_INNOBASE_STORAGE_ENGINE=1 \

-DWITH_MEMORY_STORAGE_ENGINE=1 \

-DWITH_READLINE=1 \

-DWITH_INNODB_MEMCACHED=1 \

-DWITH_DEBUG=OFF \

-DWITH_ZLIB=bundled \

-DENABLED_LOCAL_INFILE=1 \

-DENABLED_PROFILING=ON \

-DMYSQL_MAINTAINER_MODE=OFF \

-DMYSQL_TCP_PORT=3306

# 编译&安装

make && make install

配置

# 创建软连接

cd /usr/local

ln -s mysql-5.7.24 mysql

# 添加到环境变量

vim /etc/profile

export PATH=/usr/local/mysql/bin:$PATH

export PATH=/usr/local/mysql/bin:/usr/local/mysql/lib:$PATH

source /etc/profile

cd /usr/local/mysql-5.7.24

mkdir -p /usr/local/mysql-5.7.24/{data,tmp,logs,pids}

chown mysql.mysql /usr/local/mysql-5.7.24/data

chown mysql.mysql /usr/local/mysql-5.7.24/tmp

chown mysql.mysql /usr/local/mysql-5.7.24/logs

chown mysql.mysql /usr/local/mysql-5.7.24/pids

# 修改/etc/my.cnf文件，编辑配置文件如下

[mysqld]

character-set-server=utf8mb4

collation-server=utf8mb4_general_ci

datadir=/usr/local/mysql/data

socket=/usr/local/mysql/tmp/mysql.sock

[mysqld_safe]

log-error=/usr/local/mysql/logs/mysqld.log

pid-file=/usr/local/mysql/pids/mysqld.pid

[client]

default-character-set=utf8mb4

# 创建mysqld.log 和 mysqld.pid文件

touch /usr/local/mysql/logs/mysqld.log

touch /usr/local/mysql/pids/mysqld.pid

chown mysql.mysql -R /usr/local/mysql/logs/

chown mysql.mysql -R /usr/local/mysql/pids/

# 加入守护进程

cd /usr/local/mysql

cp support-files/mysql.server /etc/init.d/mysqld

chmod a+x /etc/init.d/mysqld

chkconfig --add mysqld

chkconfig mysqld on

# 初始化数据库， –initialize 表示默认生成一个安全的密码，–initialize-insecure 表示不生成密码

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

# 启动MySQL

service mysqld start

这里给一张/etc/my.cnf的配置图示

登录MySQL，修改密码

mysql -u root -p #第一次登陆不需要密码，回车即可

set password for root@localhost = password('root');  #修改密码
