内核升级
[root@localhost ~]# uname -a ##旧版
Linux localhost.localdomain 2.6.32-279.el6.i686 #1 SMP Fri Jun 22 10:59:55 UTC 2012 i686 i686 i386 GNU/Linux
[root@localhost ~]# rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org
[root@localhost ~]# rpm -ivh http://www.elrepo.org/elrepo-release-6-5.el6.elrepo.noarch.rpm
[root@localhost ~]# yum --enablerepo=elrepo-kernel install kernel-lt -y ##此步会有点慢
[root@localhost ~]# vim /etc/grub.conf default=1 改为 default=0 ##设置默认以3.10核心启动,默认是按照旧的核心启动
[root@localhost ~]# reboot
[root@localhost ~]# uname -a ##升级后的版本
CentOS 6.x 安装 php7.0
一:检查当前是否有安装php
rpm -qa|grep php
如果有安装PHP,那么请先删除这些安装包:
yum remove php*
2.安装php源
Centos 5 安装php源:
rpm -ivh http://mirror.webtatic.com/yum/el5/latest.rpm
CentOs 6 安装php源:
rpm -ivh http://mirror.webtatic.com/yum/el6/latest.rpm
CentOs 7 安装php源和epel扩展源:
rpm -ivh https://mirror.webtatic.com/yum/el7/epel-release.rpm
rpm -ivh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
3.现在开始安装php
安装php5.5的基本安装包:
yum install php55w php55w-gd php55w-mbstring php55w-mysql php55w-fpm
安装php5.6的基本安装包:
yum install php56w php55w-gd php56w-mbstring php56w-mysql php56w-fpm
安装php7.0的基本安装包:
yum install php70w php70w-gd php70w-mbstring php70w-mysql php70w-fpm
删除PHP:
#rpm -qa|grep php
删除依赖:
#rpm -e php-pdo-5.1.6-27.el5_5.3
二:nginx的yum在线安装
添加源
wget http://nginx.org/packages/centos/6/noarch/RPMS/nginx-release-centos-6-0.el6.ngx.noarch.rpm
安装源库
chmod +x nginx-release-centos-6-0.el6.ngx.noarch.rpm
rpm -i nginx-release-centos-6-0.el6.ngx.noarch.rpm
安装nginx
yum -y install nginx
安装完成后的默认配置文件路径
默认nginx配置文件: /etc/nginx/nginx.conf 【nginx主要的配置文件】
默认nginx的ssl配置文件: /etc/nginx/conf.d/ssl.conf 【配置SSL证书的,也可以并入到nginx.conf文件里】
默认nginx的虚拟主机配置文件: /etc/nginx/conf.d/virtual.conf 【如同Apache的虚拟主机配置,也可以并入到nginx.conf文件里】
默认的web_root文件夹路径: /usr/share/nginx/html 【web目录夹,放置Magento主程序】
配置iptables
iptables -I INPUT 5 -p tcp --dport 80 -j ACCEPT
(这个步骤,我之前机器上已经装过apache所以就忽略了)
安装后的目录:
配置目录:
/etc/nginx/
项目目录:
/usr/share/nginx/html/
安装Composer
CentOS下Composer的安装和使用
1. 下载composer.phar
curl -sS https://getcomposer.org/installer | php
2.把composer.phar移动到环境下让其变成可执行
mv composer.phar /usr/local/bin/composer
3.测试

安装MySQL
Step1: 检测系统是否自带安装mysql
# yum list installed | grep mysql
Step2: 删除系统自带的mysql及其依赖命令:
要删除干净mysql
# yum -y remove mysql-libs.x86_64
Step3: 给CentOS添加rpm源,并且选择较新的源命令:
# wget dev.mysql.com/get/mysql-community-release-el6-5.noarch.rpm
# yum localinstall mysql-community-release-el6-5.noarch.rpm
# yum repolist all | grep mysql
# yum-config-manager --disable mysql55-community
# yum-config-manager --disable mysql56-community
# yum-config-manager --enable mysql57-community-dmr
# yum repolist enabled | grep mysql
Step4:安装mysql 服务器命令:
# yum install mysql-community-server
Step5: 启动mysql命令:
# service mysqld start
Step6: 查看mysql是否自启动,并且设置开启自启动命令:
# chkconfig --list | grep mysqld
# chkconfig mysqld on
Step7: mysql安全设置命令:
# mysql_secure_instalation
修改mysql初始密码:
IK290yd7Dx2
方法一:
# /etc/init.d/mysqld stop
# mysqld_safe --user=mysql --skip-grant-tables --skip-networking &
# mysql -u root mysql
mysql> UPDATE user SET Password=PASSWORD('newpassword') where USER='root';
mysql> FLUSH PRIVILEGES;
mysql> quit
注:5.7 版本的 Password 字段已经改名为 authentication_string; 所以密码语句需要修改为:
UPDATE user SET authentication_string=PASSWORD('new') where USER='root';
赋权限
ALTER USER 'root'@'localhost' IDENTIFIED BY '45UIkdW230..';
grant all privileges on *.* to 'root'@'%' identified by '45UIkdW230..' with grant option;
grant all privileges on *.* to 'root'@'%' identified by '45UIkdW230..';
45UIkdW230
修改mysql时间:
rm -rf /etc/localtime
cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
-select now()

安装Redis
IK290yd7Dx2
vi /etc/redis.conf
# find # requirepass foobared
#replace it with your password
requirepass somePassword
redis 127.0.0.1:6379[1]> config set requirepass my_redis
OK
redis 127.0.0.1:6379[1]> config get requirepass
1) "requirepass"
2) "my_redis"
不重启Redis设置密码:
在配置文件中配置requirepass的密码(当redis重启时密码依然有效)。
redis 127.0.0.1:6379> config set requirepass test123
查询密码:
redis 127.0.0.1:6379> config get requirepass
(error) ERR operation not permitted
密码验证:
redis 127.0.0.1:6379> auth test123
OK
HTTPS 设置
在使用git进行代码更新时,出现认证错误,起初认为是账户和密码输入错误,可是经过再三尝试,终于确定是git版本太低问题,因此将git升级到2.x版本。以下是升级步骤。
[root@test ~]# git --version
git version 1.7.1
1、安装依赖
[root@test ~]# yum install curl-devel expat-devel gettext-devel openssl-devel zlib-devel
[root@test ~]# yum install -y perl-ExtUtils-MakeMaker package
2、卸载系统原有git
[root@test ~]# rpm -e git
3、下载git源码包
[root@test ~]# wget https://www.kernel.org/pub/software/scm/git/git-2.0.0.tar.gz
4、安装git
[root@test ~]# tar xf git-2.0.0.tar.gz
[root@test tools]# cd git-2.0.0
[root@test git-2.0.0]# ./configure
[root@test git-2.0.0]# make
[root@test git-2.0.0]# make install
[root@test git-2.0.0]# cd
5、验证
[root@test ~]# git --version
git version 2.0.0
项目配置:
etm-m-link-check 8013
etc-m-warn-report 8012
etc-m-com 8010
