一、前提

由於我安裝了幾次，我就不再講述報錯了，有點打腦殼！！！提前把相關依賴和報錯就地解決。

1、所需原始碼包

mysql-8.0.19.tar.gz 
boost_1_70_0.tar.gz		//安裝mysql-8所需要的boost版本
rpcsvc-proto-1.4.tar.gz		//後面出錯所需要的原始碼包

mysql-8.0.19下載地址：http://mirrors.sohu.com/mysql/
boost_1_70_0下載地址：https://dl.bintray.com/boostorg/release/1.70.0/source/
rpcsvc-proto-1.4下載地址：https://github.com/thkukuk/rpcsvc-proto/releases/download/v1.4/

2、解決依賴

[14:41:21 root@wangzhike ~]#yum install -y cmake ncurses-devel

3、存放位置

軟體原始碼包存放位置：/usr/local/src
原始碼包編譯安裝位置：/usr/local/軟體名字

二、編譯安裝mysql-8.0.19

1、上傳原始碼包

boost_1_70_0.tar.gz		
mysql-8.0.19.tar.gz		
rpcsvc-proto-1.4.tar.gz

2、解決rpcsvc-proto-1.4

1）、解壓

[17:05:14 root@wangzhike software]#tar -zxf rpcsvc-proto-1.4.tar.gz -C /usr/local/src/

2）、一步安裝

[17:09:48 root@wangzhike rpcsvc-proto-1.4]#./configure && make && make install

3、解決boost_1_70_0

[17:13:48 root@wangzhike~]# mkdir -p /usr/local/boost
[17:14:05 root@wangzhike~]# cd /usr/local/src
[17:15:02 root@wangzhike src]#cp /software/boost_1_70_0.tar.gz /usr/local/boost/
[17:26:22 root@wangzhike boost]#tar xf boost_1_70_0.tar.gz
////只上傳到/usr/local/src/存放目錄，解壓到當前boost目錄

4、建立mysql使用者及組

[17:27:46 root@wangzhike ~]#groupadd mysql
[17:28:10 root@wangzhike ~]#useradd -g mysql mysql -s /bin/false
####建立使用者mysql並加入到mysql組，不允許mysql使用者直接登入系統
[17:28:11 root@wangzhike ~]#mkdir -p /data/mysql 
####建立MySQL資料庫存放目錄
[17:29:13 root@wangzhike ~]#chown -R mysql:mysql /data/mysql 
####設定MySQL資料庫存放目錄許可權
[17:29:31 root@wangzhike ~]#mkdir -p /usr/local/mysql 
####建立MySQL安裝目錄

5、安裝mysql-8.0.19

1）、解壓

[17:43:24 root@wangzhike software]#tar -zxf mysql-8.0.19.tar.gz -C /usr/local/src/
[17:43:47 root@wangzhike software]#cd /usr/local/src/
[17:43:53 root@wangzhike src]#cd mysql-8.0.19/

2）、安裝

[17:47:01 root@wangzhike mysql-8.0.19]#cmake . \
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DINSTALL_DATADIR=/data/mysql -DMYSQL_USER=mysql \
-DMYSQL_UNIX_ADDR=/tmp/mysqld.sock -DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DWITH_EMBEDDED_SERVER=1 \
-DFORCE_INSOURCE_BUILD=1 \
-DWITH_MYISAM_STORAGE_ENGINE=1 \
-DENABLED_LOCAL_INFILE=1 \
-DEXTRA_CHARSETS=all \
-DWITH_BOOST=/usr/local/boost

若出現以下則沒毛病

CMake Warning: Manually-specified variables were not used by the
project:

EXTRA_CHARSETS
INSTALL_DATADIR
MYSQL_USER
WITH_EMBEDDED_SERVER

– Build files have been written to: /usr/local/src/mysql-8.0.19

若出現以下關於rpc.h的錯誤
Could not find rpc/rpc.h in /usr/include or /usr/include/tirpc

解決方法：

[17:45:47 root@wangzhike mysql-8.0.19]#find / -name rpc.h
/usr/local/src/mysql-8.0.19/extra/libevent/include/event2/rpc.h
/usr/local/src/mysql-8.0.19/plugin/group_replication/libmysqlgcs/src/bindings/xcom/xcom/windeps/sunrpc/rpc/rpc.h

####並將/usr/local/src/mysql-8.0.19/plugin/group_replication/libmysqlgcs/src/bindings/xcom/xcom/windeps/sunrpc/目錄下的rpc/rpc.h拷貝到/usr/include/

如下

[17:52:57 root@wangzhike mysql-8.0.19]#cp -a /usr/local/src/mysql-8.0.19/plugin/group_replication/libmysqlgcs/src/bindings/xcom/xcom/windeps/sunrpc/rpc /usr/include/

3）、make && install

[17:55:20 root@wangzhike mysql-8.0.19]#make -j 3 && install
//過程超長且記憶體不足的會報錯

等待等待等待

若報以下錯則表示記憶體不足需要建立分割槽

+: fatal error: Killed signal terminated program cc1plus
compilation terminated.
make[2]: *** [sql/CMakeFiles/sql_gis.dir/build.make:154: sql/CMakeFiles/sql_gis.dir/gis/distance_functor.cc.o] Error 1
make[2]: *** Waiting for unfinished jobs....
make[1]: *** [CMakeFiles/Makefile2:11144: sql/CMakeFiles/sql_gis.dir/all] Error 2
make: *** [Makefile:163: all] Error 2

建立分割槽：

[19:58:37 root@wangzhike mysql-8.0.19]#dd if=/dev/zero of=/swapfile bs=1k count=2048000
2048000+0 records in
2048000+0 records out
2097152000 bytes (2.1 GB,2.0 GiB) copied,6.07651 s,345 MB/s
####獲取要增加的2G的SWAP檔案塊
[20:10:02 root@wangzhike mysql-8.0.19]#mkswap /swapfile
mkswap: /swapfile: insecure permissions 0644,0600 suggested.
Setting up swapspace version 1,size = 2 GiB (2097147904 bytes)
no label,UUID=18a4bbb3-75d1-411b-ac0c-c87c63547509
####建立SWAP檔案
[20:10:07 root@wangzhike mysql-8.0.19]#swapon /swapfile
swapon: /swapfile: insecure permissions 0644,0600 suggested.
####啟用SWAP檔案
[20:10:12 root@wangzhike mysql-8.0.19]#swapon -s
Filename        Type   Size Used Priority
/dev/sda2        partition  2144252 137300 -2
/swapfile        file   2047996 0  -3
#####檢視SWAP資訊是否正確
[20:10:19 root@wangzhike mysql-8.0.19]#echo "/var/swapfile swap swap defaults 0 0" >> /etc/fstab
####新增到fstab檔案中讓系統引導時自動啟動

在重新執行make -j 3 && make install ，出現以下畫面則沒有報錯

```bash

三、初始化mysql資料庫

1、修改mysql目錄許可權

[20:37:59 root@wangzhike mysql-8.0.19]#chown -R mysql:mysql /usr/local/mysql
[20:42:07 root@wangzhike mysql-8.0.19]#chmod -R 755 /usr/local/mysql

2、初始化mysql

[20:45:07 root@wangzhike ~]#cd /usr/local/mysql/
[20:46:43 root@wangzhike mysql]#./bin/mysqld --initialize --user=mysql --datadir=/usr/local/mysql/data --character-set-server=utf8
2020-04-14T12:47:13.718724Z 0 [System] [MY-013169] [Server] /usr/local/mysql/bin/mysqld (mysqld 8.0.19) initializing of server in progress as process 9893
2020-04-14T12:47:13.719367Z 0 [Warning] [MY-013242] [Server] --character-set-server: 'utf8' is currently an alias for the character set UTF8MB3,but will be an alias for UTF8MB4 in a future release. Please consider using UTF8MB4 in order to be unambiguous.
2020-04-14T12:47:14.855541Z 5 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: rUG-.8kdw<1f
####生成mysql系統資料庫。

3、修改配置檔案
mysql 8.0.x預設沒有配置檔案，我們自己建立一個。

[20:49:41 root@wangzhike mysql]#vi /usr/local/mysql/my.cnf
新增以下內容：
[client]
port=3306
socket=/tmp/mysql.sock
[mysqld]
port=3306
user = mysql
socket=/tmp/mysql.sock
tmpdir = /tmp
key_buffer_size=16M
max_allowed_packet=128M
default_authentication_plugin=mysql_native_password
open_files_limit = 60000
explicit_defaults_for_timestamp
server-id = 1
character-set-server = utf8
federated
max_connections = 1000
max_connect_errors = 100000
interactive_timeout = 86400
wait_timeout = 86400
sync_binlog=0
back_log=100
default-storage-engine = InnoDB
log_slave_updates = 1
[mysqldump]
quick
[client]
password="123456"
[mysqld-8.0]
sql_mode=TRADITIONAL
[mysqladmin]
force
[mysqld]
key_buffer_size=16M
service mysqld restart

：wq！儲存退出
注意，service mysqld restart 這一句一定寫上，預設密碼為123456

其他操作

[20:53:05 root@wangzhike mysql]#ln -s /usr/local/mysql/my.cnf /etc/my.cnf
#新增到/etc目錄的軟連線
[20:53:12 root@wangzhike mysql]#cd
[20:53:13 root@wangzhike ~]#cp /usr/local/mysql/support-files/mysql.server /etc/rc.d/init.d/mysqld
#把Mysql加入系統啟動
[20:53:21 root@wangzhike ~]#chmod 755 /etc/init.d/mysqld
#增加執行許可權
[20:53:28 root@wangzhike ~]#chkconfig mysqld on
#加入開機啟動

4、編輯檔案

[20:53:39 root@wangzhike ~]#vi /etc/rc.d/init.d/mysqld

####找到basedir=並修改為/usr/local/mysql
####找到datadir=並修改為/data/mysql

basedir=/usr/local/mysql		#MySQL程式安裝路徑
datadir=/data/mysql				#MySQl資料庫存放目錄

5、開機啟動成功

[20:54:32 root@wangzhike ~]#service mysqld start
Starting MySQL.Logging to '/data/mysql/wangzhike.err'.
. SUCCESS!		#啟動成功

6、新增變數

[20:54:44 root@wangzhike ~]#vi /etc/profile

在最後一行新增export PATH=$PATH:/usr/local/mysql/bin

[20:55:37 root@wangzhike ~]#source /etc/profile			#使配置立刻生效

7、新增軟連線

[20:55:44 root@wangzhike ~]#ln -s /usr/local/mysql/lib/mysql /usr/lib/mysql
[20:55:57 root@wangzhike ~]#ln -s /usr/local/mysql/include/mysql /usr/include/mysql
####以上為把myslq的庫檔案連結到系統預設的位置

[20:56:02 root@wangzhike ~]#mkdir /var/lib/mysql
[20:56:14 root@wangzhike ~]#ln -s /tmp/mysql.sock /var/lib/mysql/mysql.sock

8、啟動mysql

[21:40:14 root@wangzhike ~]#mysql -uroot -p123456
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 9
