# 一、Mysql
|
||
|
||
#### 1、编译安装mysql5.7
|
||
|
||
1、清理安装环境：
|
||
|
||
```shell
|
||
# yum erase mariadb mariadb-server mariadb-libs mariadb-devel -y
|
||
# userdel -r mysql
|
||
# rm -rf /etc/my*
|
||
# rm -rf /var/lib/mysql
|
||
```
|
||
|
||
2、创建mysql用户
|
||
|
||
```shell
|
||
[root@mysql-server ~]# useradd -r mysql -M -s /sbin/nologin
|
||
-M 不创建用户的家目录
|
||
```
|
||
|
||
3、从官网下载tar包
|
||
|
||
wget https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-boost-5.7.27.tar.gz
|
||
|
||
4、安装编译工具
|
||
|
||
```shell
|
||
# yum -y install ncurses ncurses-devel openssl-devel bison gcc gcc-c++ make
|
||
cmake:
|
||
# yum -y install cmake
|
||
```
|
||
|
||
5、创建mysql目录
|
||
|
||
```shell
|
||
[root@mysql-server ~]# mkdir -p /usr/local/{data,mysql,log}
|
||
```
|
||
|
||
6、解压
|
||
|
||
```shell
|
||
[root@mysql-server ~]# tar xzvf mysql-boost-5.7.27.tar.gz -C /usr/local/
|
||
```
|
||
|
||
7、编译安装
|
||
|
||
```shell
|
||
cd 解压的mysql目录
|
||
[root@mysql-server ~]# cd /usr/local/mysql-5.7.27/
|
||
[root@mysql-server mysql-5.7.27]# cmake . \
|
||
-DWITH_BOOST=boost/boost_1_59_0/ \
|
||
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
|
||
-DSYSCONFDIR=/etc \
|
||
-DMYSQL_DATADIR=/usr/local/mysql/data \
|
||
-DINSTALL_MANDIR=/usr/share/man \
|
||
-DMYSQL_TCP_PORT=3306 \
|
||
-DMYSQL_UNIX_ADDR=/tmp/mysql.sock \
|
||
-DDEFAULT_CHARSET=utf8 \
|
||
-DEXTRA_CHARSETS=all \
|
||
-DDEFAULT_COLLATION=utf8_general_ci \
|
||
-DWITH_READLINE=1 \
|
||
-DWITH_SSL=system \
|
||
-DWITH_EMBEDDED_SERVER=1 \
|
||
-DENABLED_LOCAL_INFILE=1 \
|
||
-DWITH_INNOBASE_STORAGE_ENGINE=1
|
||
|
||
参数详解:
|
||
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \ 安装目录
|
||
-DSYSCONFDIR=/etc \ 配置文件存放 （默认可以不安装配置文件）
|
||
-DMYSQL_DATADIR=/usr/local/mysql/data \ 数据目录 错误日志文件也会在这个目录
|
||
-DINSTALL_MANDIR=/usr/share/man \ 帮助文档
|
||
-DMYSQL_TCP_PORT=3306 \ 默认端口
|
||
-DMYSQL_UNIX_ADDR=/tmp/mysql.sock \ sock文件位置，用来做网络通信的，客户端连接服务器的时候用
|
||
-DDEFAULT_CHARSET=utf8 \ 默认字符集。字符集的支持，可以调
|
||
-DEXTRA_CHARSETS=all \ 扩展的字符集支持所有的
|
||
-DDEFAULT_COLLATION=utf8_general_ci \ 支持的
|
||
-DWITH_READLINE=1 \ 上下翻历史命令
|
||
-DWITH_SSL=system \ 使用私钥和证书登陆（公钥） 可以加密。 适用与长连接。坏处：速度慢
|
||
-DWITH_EMBEDDED_SERVER=1 \ 嵌入式数据库
|
||
-DENABLED_LOCAL_INFILE=1 \ 从本地倒入数据，不是备份和恢复。
|
||
-DWITH_INNOBASE_STORAGE_ENGINE=1 默认的存储引擎，支持外键
|
||
```
|
||
|
||
|
||
|
||
```shell
|
||
[root@mysql-server mysql-5.7.27]# make -j4 && make install
|
||
如果安装出错，想重新安装：
|
||
不用重新解压，只需要删除安装目录中的缓存文件CMakeCache.txt
|
||
```
|
||
|
||
|
||
|
||
**需要很长时间！**大约半小时
|
||
|
||
8、初始化
|
||
|
||
```shell
|
||
[root@mysql-server mysql-5.7.27]# cd /usr/local/mysql
|
||
[root@mysql-server mysql]# chown -R mysql.mysql .
|
||
[root@mysql-server mysql]# ./bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data ---初始化完成之后，一定要记住提示最后的密码用于登陆或者修改密码
|
||
```
|
||
|
||
|
||
|
||
初始化,只需要初始化一次
|
||
|
||
```shell
|
||
[root@mysql-server ~]# vim /etc/my.cnf ---如果打开文件有内容将文件中所有内容注释掉，在添加如下内容
|
||
[mysqld]
|
||
basedir=/usr/local/mysql #指定安装目录
|
||
datadir=/usr/local/mysql/data #指定数据存放目录
|
||
```
|
||
|
||
|
||
|
||
9、启动mysql
|
||
|
||
```shell
|
||
[root@mysql-server ~]# cd /usr/local/mysql
|
||
[root@mysql-server mysql]# ./bin/mysqld_safe --user=mysql &
|
||
|
||
启动之后再按一下回车！即可后台运行
|
||
```
|
||
|
||
|
||
|
||
10、登录mysql
