liunx下安装MySQL

1．安装依赖包：
yum -y install gcc gcc-c++ ncurses ncurses-devel cmake bison
yum install -y perl-Module-Install.noarch
2．上传工具包
cd /opt
3．解压工具包
tar -xvf mysql-5.6.29.tar.gz
4.新建MySQL用户和组
groupadd -r mysql && useradd -r -g mysql -s /sbin/nologin -M mysql
5.新建MySQL数据库目录
mkdir -p /data/mysql
6．修改权限
chown -R mysql /data
7.进入MySQL解压后的工具包
cd mysql-5.6.29
8.编译mysql
cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_DATADIR=/data/mysql \
-DWITH_BOOST=../boost_1_59_0 \
-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=utf8mb4 \
-DDEFAULT_COLLATION=utf8mb4_general_ci \
-DWITH_EMBEDDED_SERVER=1
make -j `grep processor /proc/cpuinfo | wc -l`
make install
9. 安装
make install
10. 设置启动脚本，开机自动启动：
ls -lrt /usr/local/mysql
cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
chmod +x /etc/init.d/mysqld
systemctl enable mysqld

12. 添加环境变量：
echo -e '\n\nexport PATH=/usr/local/mysql/bin:$PATH\n' >> /etc/profile && source /etc/profile
13. 初始化数据库、启动mysqld服务：
mysqld --initialize-insecure --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql
14.cd /usr/local/mysql/scripts/
./mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql/data
15.启动数据库
systemctl start mysqld
mysql

 

service mysqld start
