mysql用yum安裝and編譯安裝

1.下載yum源
wget http://dev.mysql.com/get/mysql57-community-release-el7-8.noarch.rpm
或
wget 'https://dev.mysql.com/get/mysql57-community-release-el7-11.noarch.rpm'
2.安裝mysql源
yum localinstall mysql57-community-release-el7-8.noarch.rpm
3.查看mysql源是否安裝成功
yum repolist enabled | grep "mysql.-community."
4.安裝mysql
yum install mysql-community-server -y
5.關閉放火牆
systemctl stop firewalld
setenforce 0
5.開啓mysql
systemctl start mysqld
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
產看狀態
systemctl status mysqld
啓動mysql,要知道在centos7中，沒有了service命令，都是使用systemctl命令。注意啓動的時候是start mysqld而不是mysql。
查看有哪些版本的mysql:
yum repolist all | grep mysql

已啓動

1.下載安裝包
cd /usr/local/src
wget https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.20.tar.gz
2.下載boost
wget http://sourceforge.net/projects/boost/files/boost/1.59.0/boost_1_59_0.tar.gz
3.下載依賴包
yum install -y cmake bison bison-devel libaio-devel gcc gcc-c++ git ncurses-devel
4.解壓mysql
tar -zxvf mysql-5.7.20.tar.gz
將boost壓縮包移動至mysql
mv boost_1_65_1.tar.gz mysql-5.7.20
5.進入mysql原文件目錄，新建configure做爲編譯目錄，進入該目錄
cd mysql-5.7.20
mkdir configure
cd configure
6.編譯
cmake .. -DBUILD_CONFIG=mysql_release \
-DINSTALL_LAYOUT=STANDALONE \
-DCMAKE_BUILD_TYPE=RelWithDebInfo \
-DENABLE_DTRACE=OFF \
-DWITH_EMBEDDED_SERVER=OFF \
-DWITH_INNODB_MEMCACHED=ON \
-DWITH_SSL=bundled \
-DWITH_ZLIB=system \
-DWITH_PAM=ON \
-DCMAKE_INSTALL_PREFIX=/var/mysql/ \
-DINSTALL_PLUGINDIR="/var/mysql/lib/plugin" \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci \
-DWITH_EDITLINE=bundled \
-DFEATURE_SET=community \
-DCOMPILATION_COMMENT="MySQL Server (GPL)" \
-DWITH_DEBUG=OFF \
-DWITH_BOOST=..
若是編譯錯誤，先刪除CMakeCache。txt後，再從新編譯
rm -rf CMakeCache.txt
若是出現下面的提示就表示成功生成了編譯環境：
-- Configuring done
-- Generating done
7.make
成功編譯
[100%] Building CXX object sql/CMakeFiles/udf_example.dir/udf_example.cc.o
Linking CXX shared module udf_example.so
[100%] Built target udf_example
[100%] Built target my_safe_process
8.make install
9.添加mysql用戶
useradd -s /sbin/nologin mysql
10.新建數據庫文件夾及日誌文件夾，並更改用戶爲mysql
mkdir /mysql_data
mkdir /var/mysql/log
chown -R mysql:mysql /mysql_data/
chown -R mysql:mysql /var/mysql/log
創建文件，進入/var/mysql/log建立
touch error.log
賦權限子目錄及文件
chmod -R 777 /var/mysql/log
11.修改配置文件
vim /etc/my.cnf
將[mysqld]項下的內容替換爲：
[mysqld]
port=3306
datadir=/mysql_data
log_error=/var/mysql/log/error.log
basedir=/var/mysql/
注意：my.cnf文件有如下配置
socket=/var/lib/mysql/mysql.sock
須要手動創建mysql.sock,並賦值讀寫執行權限
chmod -R 777 mysql.sock
12.初始化數據庫
/var/mysql/bin/mysqld --initialize --user=mysql
查看數據文件是否生成:

[root@localhost configure]# ll /mysql_data/
總用量 110620
-rw-r-----. 1 mysql mysql       56 10月  2 19:44 auto.cnf
-rw-r-----. 1 mysql mysql      419 10月  2 19:44 ib_buffer_pool
-rw-r-----. 1 mysql mysql 12582912 10月  2 19:44 ibdata1
-rw-r-----. 1 mysql mysql 50331648 10月  2 19:44 ib_logfile0
-rw-r-----. 1 mysql mysql 50331648 10月  2 19:44 ib_logfile1
drwxr-x---. 2 mysql mysql     4096 10月  2 19:44 mysql
drwxr-x---. 2 mysql mysql     4096 10月  2 19:44 performance_schema
drwxr-x---. 2 mysql mysql    12288 10月  2 19:44 sys

查看日誌文件是否生成：

[root@localhost mysql]# ll /var/mysql/log/
總用量 4
-rw-r-----. 1 mysql mysql 802 10月  2 19:47 error.log

13.
1.從模板文件中複製啓動文件：

cp /var/mysql/support-files/mysql.server /etc/init.d/mysqld

2. 修改啓動文件：

vim /etc/init.d/mysql
找到以下二行：

basedir=
datadir=

修改成：

basedir=/var/mysql/
datadir=/mysql_data

3. 啓動mysql:

   [root@localhost mysql]# /etc/init.d/mysqld start
   Starting MySQL. SUCCESS!
