2019-06-19 编译安装MySQL5.7.20步骤

环境：已安装好系统版本CentOS7.4，虚拟机内存4G+8核i7 CPU
1.安装准备
源码包下载以及解压：

cd /tmp
wget https://downloads.mysql.com/archives/get/file/mysql-boost-5.7.20.tar.gz
tar xf mysql-boost-5.7.20.tar.gz
cd mysql-boost-5.7.20/ && mkdir debug && cd debug

安装mysql编译相关插件&&创建data目录

yum install bison cmake libaio-devel ncurses-devel -y
mkdir /data/mysql -p

2.编译安装mysql

 cmake .. -DBUILD_CONFIG=mysql_release \
-DINSTALL_LAYOUT=STANDALONE \ 
-DCMAKE_BUILD_TYPE=RelWithDebInfo \ 
-DENABLE_DTRACE=OFF \
-DWITH_EMBEDDED_SERVER=1 \
-DWITH_INNODB_MEMCACHED=ON \ 
-DWITH_SSL=bundled \
-DWITH_ZLIB=system \ 
-DWITH_PAM=ON \ 
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \ 
-DINSTALL_PLUGINDIR="/usr/local/mysql/lib/plugin" \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci \
-DWITH_EDITLINE=bundled -DFEATURE_SET=community \ 
-DWITH_DEBUG=off -DWITH_BOOST=../boost/boost_1_59_0 \ 
-DSYSCONFDIR=/etc -DMYSQL_DATADIR=/data/mysql \ 
-DMYSQL_UNIX_ADDR=/tmp/mysql.sock \
-DENABLED_LOCAL_INFILE=ON

看到 -- Configuring done -- Generating done代表编译完成且没有错误
注意：忽略警告，出现警告没有影响。
下面正式开始make编译（这里可以打开30个线程提高速度）以及安装mysql文件

make -j12 && make install
[100%] Built target mysql_client_test_embedded
-- Installing: /usr/local/mysql/support-files/mysql.server

看到以上信息证明编译和安装完成并且没有错误出现。
3.创建配置文件

cat >>/etc/mysql.cnf<<-EOF
[mysqld]
user=mysql
basedir=/usr/local/mysql
datadir=/data/mysql
server_id=1
port=3306
socket=/tmp/mysql.sock
[mysql]
socket=/tmp/mysql.sock
prompt=mysql [\\d]>
EOF

4.创建数据库

groupadd mysql;useradd  -M -g mysql mysql -s /sbin/nologin
chown -R mysql.mysql  /usr/local/mysql  /data/mysql
echo "export PATH=$PATH:/usr/local/mysql/bin" >>/etc/profile
source /etc/profile
mysqld --initialize-insecure --user=mysql --basedir=/usr/local/mysql  --datadir=/data/mysql

5.启动mysqld服务

cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
/etc/init.d/mysqld start
ss -tnl|grep 3306
LISTEN     0      80          :::3306                    :::*    

有以上信息出现证明本次安装完成
备注：设置systemctl方式启动，需要自己编制target文件并修改设置

cat >>/etc/systemd/system/mysqld.service<<-EOF
[Unit]

Documentation=man:mysqld(8)

WantedBy=multi-user.target
[Service]

Group=mysql
ExecStart=/usr/local/mysql/bin/mysqld --defaults-file=/etc/my.cnf
LimitNOFILE=5000
EOF
