12.1 LNMP架构介绍 12.2 MySQL安装 12.3/12.4 PHP安装 12.5 Nginx介绍

Nginx设计的初衷是提供一种快速、高效、多并发的Web服务软件。在静态页面的处理上，Nginx较Apache更胜一筹；但是在动态页面的处理上，Nginx并不比Apache有优势。

[root@lizhipenglinux01 src]# ps aux|grep mysql                                                       检查mysql服务有没有启动，如果有请停止服务，service mysql stop
root 5035 0.0 0.0 112676 980 pts/0 R+ 18:22 0:00 grep --color=auto mysql

[root@lizhipenglinux01 src]# rm -rf /usr/local/mysql
[root@lizhipenglinux01 src]# rm -rf /etc/init.d/mysqld                                                 删除启动脚本

[root@lizhipenglinux01 src]# vim /etc/my.cnf                                                              配置暂时保留

[root@lizhipenglinux01 src]# pwd                                                                                进入目录
/usr/local/src
[root@lizhipenglinux01 src]# wget ....^C                                                                    wget下载包
[root@lizhipenglinux01 src]# tar zxvf mysql-5.6.36-linux-glibc2.5-x86_64.tar.gz        解压

[root@lizhipenglinux01 src]# mv mysql-5.6.36-linux-glibc2.5-x86_64 /usr/local/        更改名字，确保没有出现mysql
apache2/ apr/ bin/ games/ lib/ libexec/ php/ sbin/ src/
apache2.4/ apr-util/ etc/ include/ lib64/ mariadb/ php7/ share/
[root@lizhipenglinux01 src]# mv mysql-5.6.36-linux-glibc2.5-x86_64 /usr/local/mysql       更改名字，确保没有出现mysql
[root@lizhipenglinux01 src]# ls /usr/local/mysql/
bin COPYING data docs include lib man mysql-test README scripts share sql-bench support-files

[root@lizhipenglinux01 mysql]# ls /data/                                                                 创建目录，之前已经创建了
mariadb mysql wwwroot
[root@lizhipenglinux01 mysql]# id mysql                                                                 创建用户mysql，之前已经创建了
uid=1008(mysql) gid=1008(mysql) 组=1008(mysql)

[root@lizhipenglinux01 mysql]# ls
bin COPYING data docs include lib man mysql-test README scripts share sql-bench support-files
[root@lizhipenglinux01 mysql]# rm -rf /data/mysql/*                                                 把mysql里面的东西清空掉

[root@lizhipenglinux01 mysql]# ./scripts/mysql_install_db --user=mysql --datadir=/data/mysql

[root@lizhipenglinux01 mysql]# echo $?
0

编辑配置文件

[root@lizhipenglinux01 mysql]# cp support-files/mysql.server /etc/init.d/mysqld                          拷贝启动脚本

[root@lizhipenglinux01 mysql]# vim /etc/init.d/mysqld

[root@lizhipenglinux01 mysql]# chkconfig --add mysqld             mysqld加入到服务列表
[root@lizhipenglinux01 mysql]# chkconfig mysqld on                  开机自启
[root@lizhipenglinux01 mysql]# service mysql stop
Redirecting to /bin/systemctl stop mysql.service
[root@lizhipenglinux01 mysql]# service mysqld stop
Shutting down MySQL.. SUCCESS!
[root@lizhipenglinux01 mysql]# service mysqld start
Starting MySQL. SUCCESS!

 

[root@lizhipenglinux01 src]# cd php-5.6.30/
[root@lizhipenglinux01 php-5.6.30]# pwd
/usr/local/src/php-5.6.30
[root@lizhipenglinux01 php-5.6.30]# make clean                      之前编译过的文件全部删掉
find . -name \*.gcno -o -name \*.gcda | xargs rm -f
find . -name \*.lo -o -name \*.o | xargs rm -f
find . -name \*.la -o -name \*.a | xargs rm -f
find . -name \*.so | xargs rm -f
find . -name .libs -a -type d|xargs rm -rf
rm -f libphp5.la sapi/cli/php sapi/cgi/php-cgi libphp5.la modules/* libs/*             删完以后处于刚刚解压的状态，之后编译针对Nginx的PHP
