CentOS7编译安装MySQL5.7.24

目录

• 安装依赖
• 安装boost
• 编译安装MySQL
• 配置
• 登录MySQL，修改密码

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
