Nginx: error while loading shared libraries: libpcre.so.1解决

Shell代码

[ew69@localhost conf]# /usr/local/nginx/sbin/nginx

/usr/local/nginx/sbin/nginx: error while loading shared libraries: libpcre.so.1: cannot open shared object file: No such file or directory

确认已经安装PCRE:

Shell代码

[ew69@SCLABHADOOP01 lib]$ cd /lib

[ew69@SCLABHADOOP01 lib]$ ls *pcre*

libpcre.so.0  libpcre.so.0.0.1

[hadoop@SCLABCLUS01 nginx]$ find / -type f -name *libpcre.so.*

添加软链接:

Shell代码

[ew69@SCLABHADOOP01 lib]$ ln -s /lib/libpcre.so.0.0.1 /lib/libpcre.so.1

前面在一般的linux上可以解决此问题.

注: 在有的操作系统上面,安装pcre后,安装的位置为/usr/local/lib/*pcre*

在redhat 64位机器之上有这样的情况.

在redhat 64位机器上, nginx可能读取的pcre文件为/lib64/libpcre.so.1文件.

所以在改用下面的软连接:

Shell代码

[hadoop@SCLABHADOOP01 ~]$ ln -s /usr/local/lib/libpcre.so.1 /lib64/

mysql

修改密码 刷新权限和重启mysql update user set password=password('自己的密码') where user='root'; flush privileges; service mysqld restart;
删除匿名用户
在MySQL刚刚被安装后，存在用户名、密码为空的用户。这使得数据库服务器有无需密码被登录的可能性。为消除隐患，将匿名用户删除。
[root@sample ~]# mysql -u root -p　 ← 通过密码用root登录 Enter password:　 ← 在这里输入密码

CentOS下开启mysql远程连接，远程管理数据库
2012-08-16 08:47:40| 分类： mysql |举报|字号 订阅 当服务器没有运行php、没装phpmyadmin的时候，远程管理mysql就显得有必要了。因为在CentOS下设置的，所以标题加上了CentOS，以下的命令在debian等系统下应该也OK。
mysql -u root -p mysql # 第1个mysql是执行命令，第2个mysql是系统数据名称 在mysql控制台执行:
grant all privileges on *.* to 'root'@'%' identified by '远程登录的密码,可以和本地的不同' with grant option; # root是用户名，%代表任意主机，'123456'指定的登录密码（这个和本地的root密码可以设置不同的，互不影响） flush privileges; # 重载系统权限 exit; 允许3306端口
iptables -I INPUT -p tcp -m state --state NEW -m tcp --dport 3306 -j ACCEPT # 查看规则是否生效 iptables -L -n # 或者: service iptables status
# 此时生产环境是不安全的，远程管理之后应该关闭端口，删除之前添加的规则 iptables -D INPUT -p tcp -m state --state NEW -m tcp --dport 3306 -j ACCEPT PS，上面iptables添加/删除规则都是临时的，如果需要重启后也生效，需要保存修改: service iptables save # 或者: /etc/init.d/iptables save 另外， vi /etc/sysconfig/iptables # 加上下面这行规则也是可以的 -A INPUT -p tcp -m state --state NEW -m tcp --dport 3306 -j ACCEPT
远程管理数据库的软件，win系统下可以使用SQLyog，用了几种远程软件，感觉这个用起来蛮不错的。 webmin root 系统密码
服务器为多网卡,找出到公网的网口.利用-i [port_name]配置允许访问TCP:22和TCP:1521;其他协议及端口默认拒绝. iptables -A INPUT -i eth1 -p tcp --dport 22 -j ACCEPT iptables -A INPUT -i eth1 -p tcp --dport 80 -j ACCEPT iptables -A INPUT -i eth1 -p tcp --dport 10000 -j ACCEPT iptables -A INPUT -i eth1 -j DROP 运行/etc/rc.d/init.d/iptables save保存配置文件到/etc/sysconfig/iptables下
运行service iptables restart确认重启iptables后规则仍有效.
