本文主要给大家介绍mysql5.7编译安装流程简析，希望可以给大家补充和更新些知识，如有其它问题需要了解的可以持续在行业资讯里面关注我的更新文章的。

mysql5.7编译安装过程

mkdir -p /data/{mysql,conf}

下载mysql5.7源码包

cd /usr/local/src
wget https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.22.tar.gz
tar xf mysql-5.7.22.tar.gz

下载boost

wget http://www.sourceforge.net/projects/boost/files/boost/1.59.0/boost_1_59_0.tar.gz
tar -zxvf boost_1_59_0.tar.gz -C /usr/local
mv /usr/local/boost_1_59_0 /usr/local/boost

#安装
yum -y groupinstall "Development tools"

yum -y install wget iproute iotop mtr perf telnet dstat iftop vim cmake gcc gcc-c++ bison ncurses ncurses-devel

yum -y install  libxml2 libxml2-devel openssl-devel bzip2 bzip2-devel libcurl-devel libjpeg libjpeg-devel libpng-devel libicu-devel libmcrypt-devel freetype-devel libtidy libtidy-devel ImageMagick-devel mhash mhash-devel pcre-devel libzip postgresql-devel

groupadd -g 306 mysql
useradd -g mysql -u 306 -s /sbin/nologin -M mysql
mkdir /data/mysql -pv
chown -R mysql.mysql /data/mysql
cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_DATADIR=/data/mysql -DWITH_BOOST=/usr/local/boost -DSYSCONFDIR=/etc -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_PARTITION_STORAGE_ENGINE=1 -DWITH_FEDERATED_STORAGE_ENGINE=1 -DWITH_BLACKHOLE_STORAGE_ENGINE=1 -DWITH_MYISAM_STORAGE_ENGINE=1 -DENABLED_LOCAL_INFILE=1 -DENABLE_DTRACE=0 -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DWITH_EMBEDDED_SERVER=1

make && make install

#设置权限
chown -R mysql:mysql /data/mysql

添加配置文件

vim /etc/my.cnf
[mysqld]
port=3306
basedir=/usr/local/mysql
datadir=/data/mysql
character-set-server=utf8
default-storage-engine=InnoDB
max_connections=5120

query_cache_size=0
tmp_table_size=18M
log-error = /data/mysql/mysql-error.log

thread_cache_size=8
myisam_max_sort_file_size=64G
myisam_sort_buffer_size=35M
key_buffer_size=25M
read_buffer_size=64K
read_rnd_buffer_size=256K
sort_buffer_size=256K

innodb_flush_log_at_trx_commit=1
innodb_log_buffer_size=1M
innodb_buffer_pool_size=47M
innodb_log_file_size=24M
innodb_thread_concurrency=8

初始化mysql

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

添加MySQL环境变量

echo "export PATH=/usr/local/mysql/bin:$PATH" >> /etc/profile
source /etc/profile

导出头文件

ln -sv /usr/local/mysql/include /usr/include/mysqld

导出库文件

echo "/usr/local/mysql/lib" > /etc/ld.so.conf.d/mysql.conf
ldconfig

添加启动脚本

cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
chmod +x /etc/init.d/mysqld
chkconfig --add mysqld

启动服务,启动服务之后可以直接无码密码登录,如果无法登录继续下面两步

/etc/init.d/mysqld start

找到mysql5.7的初始密码

grep "temporary password" /data/mysql/mysql-error.log
2018-09-25T06:30:28.930040Z 1 [Note] A temporary password is generated for root@localhost: Ui4/OupkjroO

修改密码

mysql -uroot -pUi4/OupkjroO
mysql>alter user root@localhost identified by 'yourpassword';
