学以致用十六-----Centos7.2编译安装mysql5.6.22

一、系统环境

二、卸载系统自带的mariadb

rpm -qa | grep db

rpm -e --nodeps mariadb-libs-5.5.60

rpm -e --nodeps mariadb-devel-5.5.60

三、安装依赖包

yum -y install wget sqlite-devel xz gcc automake zlib-devel openssl-devel epel-release git lsof

yum -y  install ncurses-devel

yum install -y perl-Module-Build.noarch

四、安装cmake   3.0以上

cmake 3.12.2

./configure

gmake

make install

五、创建用户

useradd  mysql

六、创建mysql需要的目录

mkdir /usr/local/mysql

mkdir /var/lib/mysql

七、安装mysql

cmake -DCMAKE_INSALL_PREFIX=/usr/local/mysql -DMYSQL_DATADIR=/var/lib/mysql -DSYSCONFDIR=/etc

make ; make install

八、设置配置文件

cp /usr/local/mysql/support-files/my-default.cnf  /etc/my.cnf

九、初始化数据库

#cd /usr/local/mysql/scripts
# ./mysql_install_db --basedir=/usr/local/mysql --datadir=/var/lib/mysql

十、配置环境变量

#vi /etc/profile
PATH=/usr/local/mysql/bin:/usr/local/mysql/lib:$PATH
#export PATH
#source /etc/profile

十一、设置mysql用户权限

chown -R mysql:mysql /var/lib/mysql

十二、启动mysql

service mysql start

十三、设置mysql密码

mysql> use mysql
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A
Database changed
mysql> update user set password=PASSWORD('root') where user='root';
Query OK, 4 rows affected (0.03 sec)
Rows matched: 4 Changed: 4 Warnings: 0
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

十四、设置mysql快捷方式

ln -s /usr/local/mysql/bin/mysql /usr/bin

至此mysql 安装完毕。

安装过程中，遇到的错误

a、如果没有安装  ncurses-devel

会报错

cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
> -DMYSQL_DATADIR=/var/lib/mysql -DSYSCONFDIR=/etc
报错啦
-- Could NOT find Curses (missing: CURSES_LIBRARY CURSES_INCLUDE_PATH)
CMake Error at cmake/readline.cmake:85 (MESSAGE):
Curses library not found. Please install appropriate package,
remove CMakeCache.txt and rerun cmake.On Debian/Ubuntu, package name is libncurses5-dev, on Redhat and derivates it is ncurses-devel.

解决方法 ： 根据蓝色色体提示 安装 ncurses-devel
rm -rf CMakeCache.txt
yum install ncurses-devel

b、初始化数据库报错

#cd /usr/local/mysql/scripts
# ./mysql_install_db --basedir=/usr/local/mysql --datadir=/var/lib/mysql
