lamp环境搭建之编译安装mysql

Posted 2021-01-15 风风羊

mysql 编译安装
1，在网站上下载： wget http://dev.mysql.com/get/Downloads/MySQL-5.6/mysql-5.6.15.tar.gz

2，安装cmake yum安装即可。（“CMake”这个名字是“cross platform make”的缩写,）

3，cmake使用报错：
-- The CXX compiler identification is unknown
CMake Error: your CXX compiler: "CMAKE_CXX_COMPILER-NOTFOUND" was not found.
Please set CMAKE_CXX_COMPILER to a valid compiler path or name.

解决：报错大致都是缺少依赖包，安装这些就差不多了
yum install -y git gcc gcc-c++ ncurses-devel bison

4，再次执行cmake命令
cmake
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql
-DMYSQL_DATADIR=/usr/local/mysql/data
-DSYSCONFDIR=/etc
-DWITH_MYISAM_STORAGE_ENGINE=1
-DWITH_INNOBASE_STORAGE_ENGINE=1
-DWITH_MEMORY_STORAGE_ENGINE=1
-DWITH_READLINE=1
-DMYSQL_UNIX_ADDR=/var/lib/mysql/mysql.sock
-DMYSQL_TCP_PORT=3306
-DENABLED_LOCAL_INFILE=1
-DWITH_PARTITION_STORAGE_ENGINE=1
-DEXTRA_CHARSETS=all
-DDEFAULT_CHARSET=utf8
-DDEFAULT_COLLATION=utf8_general_ci

5，make && make install

6，报错 make[2]: *** [sql/CMakeFiles/sql.dir/mysqld.cc.o] Error 1
make[1]: *** [sql/CMakeFiles/sql.dir/all] Error 2
make: *** [all] Error 2

解决：make clean
rm CMakeCache.txt

7，创建mysql用户和用户组，更改mysql 目录的默认用户
groupadd mysql
useradd mysql -g mysql -s /sbin/nologin
chown -R mysql:mysql /usr/local/mysql

8，复制配置文件到/etc 目录下
cp /usr/local/mysql/support-files/my-default.cnf /etc/my.cnf

9，添加到环境变量中
echo ‘export PATH=/usr/local/mysql/bin:$PATH‘ >> /etc/profile
source /etc/profile

10，添加进启动项
cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld

11，初始化mysql数据库报错：
FATAL ERROR: Could not find ./bin/my_print_defaults
解决：在/bin 目录下看能否找到 这个文件，如果有，就到安装目录以相对路劲执行。
如下：./scripts/mysql_install_db --defaults-file=/etc/my.cnf --user=mysql

12，PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:

./bin/mysqladmin -u root password ‘new-password‘ #更改mysql的root密码
./bin/mysqladmin -u root -h tao-ffy.ffy.com password ‘new-pass
