centosphp重裝

1. 如何在centos上安裝php

.1 安裝Apahce, PHP, MySQL以及php連接mysql庫組件。 #yum -y install httpd php mysql mysql-server php-mysql 2. 安裝apache擴展 #yum -y install httpd-manual mod_ssl mod_perl mod_auth_mysql 3. 安裝php的擴展 #yum -y install php-gd php-xml php-mbstring php-ldap php-pear php-xmlrpc 4. 安裝MySQL的擴展 #yum -y install mysql-connector-odbc mysql-devel libdbi-dbd-mysql

遇到類似的問題，你可以去後盾人平台看看的哦，裡面的東西不錯應該能幫你解決一些不明白的問題(❁´◡`❁)*

2. centOS怎樣強制卸載PHP以及自定義安裝PHP

查看php版本命令：
#php -v
這個命令是刪除不幹凈的
#yum remove php
因為使用這個命令以後再用
#php -v
還是會看到有版本信息的。。。。。
必須強制刪除
#rpm -qa|grep php
提示如下
#php-pdo-5.1.6-27.el5_5.3
#php-mysql-5.1.6-27.el5_5.3
#php-xml-5.1.6-27.el5_5.3
#php-cli-5.1.6-27.el5_5.3
#php-common-5.1.6-27.el5_5.3
#php-gd-5.1.6-27.el5_5.3
注意卸載要先卸載沒有依賴的
pdo是mysql的依賴項；common是gd的依賴項；
例如：# rpm -e php-pdo-5.1.6-27.el5_5.3
error: Failed dependencies:
php-pdo is needed by (installed) php-mysql-5.1.6-27.el5_5.3.i386
所以正確的卸載順序是：
# rpm -e php-mysql-5.1.6-27.el5_5.3
# rpm -e php-pdo-5.1.6-27.el5_5.3
# rpm -e php-xml-5.1.6-27.el5_5.3
# rpm -e php-cli-5.1.6-27.el5_5.3
# rpm -e php-gd-5.1.6-27.el5_5.3
# rpm -e php-common-5.1.6-27.el5_5.3
再用# php -v
查看版本信息已經沒有提示
安裝最新的PHP
wget
tar xzvf php-5.3.6.tar.gz
cd php-5.3.6
./configure --prefix=/usr/local/php如果你還不明白的話，你可以在後盾人看看教材視頻，多看看幾遍，慢慢的不就會了，如果嫌棄麻煩，你可以直接去後盾網問問那些專家講師，他們很樂意幫你的，希望能幫到你，給個採納吧謝謝，

3. centos 如何檢測php安裝

需要准備的材料分別是：電腦、centos主機，linux連接工具。

1、首先連接上centos主機，進入等待輸入指令的linux命令行狀態。

4. centos6.5怎麼安裝php5.5

1.******已安裝Nginx******
ps -aux | grep nginx
netstat -anptu | grep 80

2.清除系統中php痕跡：
yum remove php
rm -rvf /etc/php
rm -rvf /etc/php.ini
rm -f /usr/bin/php

3.安裝php所需軟體包：
tar zxvf autoconf-2.68.tar.gz -C /usr/src
cd /usr/src/autoconf-2.68/
./configure && make && make install
tar zxvf libiconv-1.14.tar.gz -C /usr/src
cd /usr/src/libiconv-1.14/
./configure && make && make install
tar zxvf libmcrypt-2.5.8.tar.gz -C /usr/src
cd /usr/src/libmcrypt-2.5.8/
./configure && make && make install
ldconfig
cd libltdl/
./configure --enable-ltdl-install
make && make install
export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH
tar zxvf mhash-0.9.9.9.tar.gz -C /usr/src
cd /usr/src/mhash-0.9.9.9/
./configure && make && make install
tar zxvf mcrypt-2.6.8.tar.gz -C /usr/src
cd /usr/src/mcrypt-2.6.8/
./configure && make && make install

4.載入php動態模塊：
ln -s /usr/local/lib/libmcrypt.la /usr/lib64/libmcrypt.la
ln -s /usr/local/lib/libmcrypt.so /usr/lib64/libmcrypt.so
ln -s /usr/local/lib/libmcrypt.so.4 /usr/lib64/libmcrypt.so.4
ln -s /usr/local/lib/libmcrypt.so.4.4.8
/usr/lib64/libmcrypt.so.4.4.8
ln -s /usr/local/lib/libmhash.a /usr/lib64/libmhash.a
ln -s /usr/local/lib/libmhash.la /usr/lib64/libmhash.la
ln -s /usr/local/lib/libmhash.so /usr/lib64/libmhash.so
ln -s /usr/local/lib/libmhash.so.2 /usr/lib64/libmhash.so.2
ln -s /usr/local/lib/libmhash.so.2.0.1
/usr/lib64/libmhash.so.2.0.1
cp -R /usr/lib64/libpng.* /usr/lib/
cp -R /usr/lib64/libjpeg.* /usr/lib/
echo "/lib" >> /etc/ld.so.conf
echo "/usr/lib" >> /etc/ld.so.conf
echo "/usr/lib64" >> /etc/ld.so.conf
echo "/usr/local/lib" >> /etc/ld.so.conf
echo "* soft nproc 65535" >> /etc/security/limits.conf
echo "* hard nproc 65535" >> /etc/security/limits.conf
echo "* soft nofile 65535" >> /etc/security/limits.conf
echo "* hard nofile 65535" >> /etc/security/limits.conf
echo "fs.file-max=65535" >> /etc/sysctl.conf

ldconfig

5.解壓、配置、編譯、安裝php：
tar zxvf php-5.5.25.tar.gz -C /usr/src
cd /usr/src/php-5.5.25/
./configure --prefix=/usr/local/php \
--with-config-file-path=/usr/local/php/etc \

10.創建目錄並修改許可權，重啟nginx服務：
mkdir -p /home/php/log
mkdir -p /home/php/pid
chown -R www:www /home/php/log
chown -R www:www /home/php/pid
service nginx restart

11.添加php-fpm系統服務：
chmod +x /etc/init.d/php-fpm
chkconfig --add php-fpm
chkconfig --level 2345 php-fpm on
chkconfig --list | grep php-fpm

12.啟動php-fpm服務：
service php-fpm start
ps -aux | grep php-fpm
netstat -anptu | grep 9000

13.配置php測試頁：
vim /home/www/html/phpinfo.php

5. 阿里雲默認centos7上怎麼安裝php

首先更新系統軟體</str>
$ yum update
安裝nginx</str></str>
1.安裝nginx源
$ yum localinstall http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm2.安裝nginx
$ yum install nginx
3.啟動nginx
$ service nginx start
Redirecting to /bin/systemctl start nginx.service4.訪問http://你的ip/
如果成功安裝會出來nginx默認的歡迎界面
安裝MySQL5.7.*
</str>
1.安裝mysql源</str>
$ yum localinstall http://dev.mysql.com/get/mysql57-community-release-el7-7.noarch.rpm2.安裝mysql
$ yum install mysql-community-server
確認一下mysql的版本，有時可能會提示mysql5.63.安裝mysql的開發包，以後會有用
$ yum install mysql-community-devel
4.啟動mysql
$ service mysqld start
Redirecting to /bin/systemctl start mysqld.service5.查看mysql啟動狀態
$ service mysqld status
出現pid
證明啟動成功
6.獲取mysql默認生成的密碼
$ grep 'temporary password' /var/log/mysqld.log2015-12-05T05:41:09.104758Z 1 [Note] A temporary password is generated for root@localhost: %G1Rgns!dD!v</str>
加粗的就是生成的密碼
7.換成自己的密碼
$ mysql -uroot -p
Enter password:輸入上面的密碼
成功輸入後進入一下步，這里你估計會輸入 好幾次才進去8. 更換密碼
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPass4!';這個密碼一定要足夠復雜，不然會不讓你改，提示密碼不合法;9.退出mysql;
mysql> quit;
10.用新密碼再登錄，試一下新密碼
$ mysql -uroot -p
Enter password:輸入你的新密碼
11.確認密碼正確後，退出mysql;
mysql> quit;
編譯安裝php7.0.0
</str>
</str>
1.下載php7源碼包</str>
$ cd /root & wget -O php7.tar.gz http://cn2.php.net/get/php-7.0.1.tar.gz/from/this/mirror2.解壓源碼包</str>
$ tar -xvf php7.tar.gz
3.</str>
$ cd php-7.0.1
4.安裝php依賴包</str>
</str>
$ yum install libxml2 libxml2-devel openssl openssl-devel bzip2 bzip2-devel libcurl libcurl-devel libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel gmp gmp-devel libmcrypt libmcrypt-devel readline readline-devel libxslt libxslt-devel5.編譯配置，這一步我們會遇到很多configure error，我們一一解決，基本都是相關軟體開發包沒有安裝導致</str>

6. centos7 已有php怎麼安裝

檢查是否以前安裝過php ，將其刪除
yum remove php* php-common
rpm 安裝 Php7 相應的 yum源
rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm

如果出現下面錯誤
yum -y install epel-release

4
yum install php70w

7. centos下安裝php

yum install -y php
## 這個只安裝PHP
## 建議安裝運行庫及MySQL的支持
yum install -y php php-devel php-mysql
## 如果你的系統是CentOS 5.6那麼上面這條命令安裝的是PHP 5.1,要安裝 PHP 5.3則執行下面的命令:
yum install -y php53 php53-devel php53-mysql

8. Centos7怎麼做安裝PHP7最新版

直接下載PHP7.0.2的安裝包解壓，編譯，安裝:
下載php7,並解壓
$ cd /usr/src/
$ wget
#解壓
$ tar -xzxvf php-7.0.2.tar.gz
$ cd php-7.0.2
解壓完後先不要編譯，請檢查是否安裝了gcc ,沒有的話執行yum install gcc
檢查是否安裝了libxml2 ,沒有的話執行yum install libxml2
檢查是否安裝了libxml2-devel,沒有的話執行yum install libxml2-devel
註：因為改為用nginx了，所以編譯參數中的--with-apxs2=/usr/bin/apxs去掉了，如果要配置apache用，安裝PHP前，請先安裝apache。

9. 阿里雲上的centos 7.2怎麼yum安裝php 5.6

因之前通過網易的 centos 鏡像，將阿里雲的 centos 升級到最新版了，乘自己的項目尚未開始正式開發，遂將所有的相應環境都升級到最高。
查看 centos 版本：
[root@iZ23d ~]# cat /etc/centos-release
CentOS Linux release 7.2.1511 (Core)
1、刪除之前的 php 版本：
[root@iZ23d ~]# yum remove php* php-common
Loaded plugins: langpacks
Repository base is listed more than once in the configuration
Repository updates is listed more than once in the configuration
Repository extras is listed more than once in the configuration
Repository centosplus is listed more than once in the configuration
No Match for argument: php-5.4.16
No Match for argument: php-5.4.16.tar.gz
No Match for argument: php-7.0.1RC1
No Match for argument: php-7.0.1RC1.tar.gz
No Match for argument: phpMyAdmin-4.4.0.tar.gz
No Match for argument: php-common
No Packages marked for removal
2、rpm 安裝 Php7 相應的 yum源：
[root@iZ23d ~]# rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
Retrieving https://mirror.webtatic.com/yum/el7/webtatic-release.rpm

Preparing... ################################# [100%]
package webtatic-release-7-3.noarch is already installed
3、 直接yum安裝php7：
[root@iZ23d ~]# yum install php70w
Loaded plugins: langpacks
Repository base is listed more than once in the configuration
Repository updates is listed more than once in the configuration
Repository extras is listed more than once in the configuration

4、檢查 php 版本：
[root@iZ23d ~]# php -v
PHP 7.0.0 (cli) (built: Dec 2 2015 20:42:32) ( NTS )
Copyright (c) 1997-2015 The PHP Group

[root@iZ23d2e6hoqZ ~]#
以上顯示安裝成功！
5、重啟 Apache，查看 phpinfo :
[root@iZ23d ~]# systemctl restart httpd.service
檢查phpinfo:

以上顯示 php7 安裝成功！

10. CentOS怎樣強制卸載PHP以及自定義安裝PHP

查看php版本命令：

#php -v

這個命令是刪除不幹凈的

#yum remove php

因為使用這個命令以後再用

#php -v

還是會看到有版本信息的。。。。。

必須強制刪除

#rpm -qa|grep php

提示如下

#php-pdo-5.1.6-27.el5_5.3
#php-mysql-5.1.6-27.el5_5.3
#php-xml-5.1.6-27.el5_5.3
#php-cli-5.1.6-27.el5_5.3
#php-common-5.1.6-27.el5_5.3
#php-gd-5.1.6-27.el5_5.3

注意卸載要先卸載沒有依賴的

pdo是mysql的依賴項；common是gd的依賴項；
例如：# rpm -e php-pdo-5.1.6-27.el5_5.3
error: Failed dependencies:
php-pdo is needed by (installed) php-mysql-5.1.6-27.el5_5.3.i386

所以正確的卸載順序是：
# rpm -e php-mysql-5.1.6-27.el5_5.3
# rpm -e php-pdo-5.1.6-27.el5_5.3
# rpm -e php-xml-5.1.6-27.el5_5.3
# rpm -e php-cli-5.1.6-27.el5_5.3
# rpm -e php-gd-5.1.6-27.el5_5.3
# rpm -e php-common-5.1.6-27.el5_5.3

再用# php -v

查看版本信息已經沒有提示

安裝最新的PHP

wget
tar xzvf php-5.3.6.tar.gz

cd php-5.3.6

./configure --prefix=/usr/local/php
