mysql5.7最新版安装

mysql version：RHEL6.4_x64 /centos6.5
linux version: mysql5.7.2-m12

mysql安装方式分为源代码安装和软件包安装；软件包安装简单，源代码安装定制性强。由于软件包安装简单，这里不再赘述。已源代码安装为主


2.1 安装兼容性软件包
yum -y install cmake ncurses-devel gcc gcc-c++ autoconf automake zlib libxml libgcrypt libtool
2.2 安装前的准备
同步服务器时钟（硬件时钟要与本地服务器时间一致）
(1)hwclock --hctosys
(2)ntpdate pool.ntp.org
  clock -w
创建mysql用户和组
useradd -r -s /sbin/nologin mysql
创建mysql数据目录,并修改权限
mkdir /data/mysql -p
chown -R mysql:mysql /data/mysql
chmod 755 -R /data/mysql
上传/下载mysql源码包
cd /usr/lobal/src


解压源代码包
tar -zxvf mysql-5.7.2-m12.tar.gz


2.3配置编译mysql
cd mysql-5.7.2-m12
cmake \
-DCMAKE_BUILD_TYPE:STRING=Release \
-DCMAKE_INSTALL_PREFIX:PATH=/usr/local/mysql \
-DCOMMUNITY_BUILD:BOOL=ON \
-DENABLED_PROFILING:BOOL=ON \
-DENABLE_DEBUG_SYNC:BOOL=OFF \
-DINSTALL_LAYOUT:STRING=STANDALONE \
-DMYSQL_DATADIR:PATH=/data/mysql \
-DMYSQL_MAINTAINER_MODE:BOOL=OFF \
-DWITH_EMBEDDED_SERVER:BOOL=ON \
-DWITH_EXTRA_CHARSETS:STRING=all \
-DWITH_SSL:STRING=bundled \
-DWITH_UNIT_TESTS:BOOL=OFF \
-DWITH_ZLIB:STRING=bundled \
-DENABLE_DTRACE=OFF


make && make install
（时间比较长）


2.4安装mysql
chown -R mysql:mysql /usr/local/mysql
chmod -R 755 /usr/local/mysql
chown -R mysql:mysql /var/lib/mysql
chmod -R 755 /var/lib/mysql
ln -s /usr/local/mysql/lib/libmysqlclient.so.18 /usr/lib/.


vim /etc/my.cnf
[mysqld]
datadir=/data/mysql
socket=/var/lib/mysql/mysql.sock
user=mysql
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0


[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/lib/mysql/mysqld.pid


[client]
socket=/var/lib/mysql/mysql.sock


./scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql
2.5配置文件
添加启动项
cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
vim /etc/init.d/mysqld
basedir=/usr/local/mysql
datadir=/data/mysql
chmod +x /etc/init.d/mysqld
chkconfig --add mysqld
chkconfig mysqld on
vim /root/.bash_profile
PATH=$PATH:$HOME/bin:/usr/local/mysql/bin


source ~/.bash_profile


2.6 启动数据库，初始化mysql密码
service mysqld start
mysqladmin -u root password mysql


2.7测试数据是否成功
mysql -u root –pmysql
select version();               #查看版本
status                       #还是查看版本
